Porcelain, Rim diam 216mmPestle height 190mmMortar and pestle is a set of 2 simple tools used since the stone age up to the present day to prepare ingredients or substances by crushing and grinding them into a fine paste or powder in the kitchen, laboratory, and pharmacy. The mortar is a bowl, typically made of hard wood, metal, ceramic, or hard stone, such as granite. The pestle is a blunt club-shaped object. The substance to be ground, which may be wet or dry, is placed in the mortar, where the pestle is pounding, pressing and rotating onto the substance, until the desired texture is achieved.Mortars and pestles have been used in cooking since prehistory; they are also frequently associated with the profession of pharmacy due to their historical use in preparing medicines. Mortars and pestles can also be used in chemistry for pulverizing small amounts of chemicals; in arts and cosmetics for pulverizing pigments, binders, and other sub-stances; in ceramics for making grog; in masonry and in other types of construction requiring pulverization of materials. In cooking, mortars and pestle are especially used to crush spices and to make pesto, and certain cocktails, such as the mojito, require the gentle crushing of sug-ar, ice and mint leaves in the glass with a pestle.

Dialysis tubing, also known as Visking tubing, is an artificial semi-perme-able membrane tubing[1] used in separation techniques, that facilitates the flow of tiny molecules in solution based on differential diffusion. In the context of life science research, dialysis tubing is typically used in the sample clean-up and processing of proteins and DNA samples or complex biological samples such as blood or serums. Dialysis tubing is also frequently used as a teaching aid to demonstrate the principles of diffusion, osmosis, Brownian motion and the movement of molecules across a restrictive membrane.

size: 20x20cmPack of 100 sheetsPaper chromatography is an analytical method used to separate coloured chemicals or substances. Erwin Chargaff credits in Weintraub’s history of the man the 1944 article by Consden, Gordon and Martin with sparking his discovery of Chargaff’s rules, an important precursor to Watson and Crick‘s discovery of the double-helix structure of DNA, for which they were awarded the Nobel Prize in Physiology or Medicine in 1962. It is now primarily used as a teaching tool, having been replaced in the laboratory by other chromatography methods such as thin-layer chromatography (TLC).A paper chromatography variant, two-dimensional chromatography involves using two solvents and rotating the paper 90° in between. This is useful for separating complex mixtures of compounds having similar polarity, for example, amino acids. The setup has three components. The mobile phase is a solution that travels up the stationary phase, due to capillary action. The mobile phase is generally a mixture of non-polar organic solvent, while the stationary phase is polar inorganic solvent water. Here paper is used to support the stationary phase, water. Polar water molecules are held inside the void space of the cellulose network of the host paper. The difference between TLC and paper chromatography is that the stationary phase in TLC is a layer of adsorbent (usually silica gel, or aluminium oxide), and the stationary phase in paper chromatography is less absorbent paper.

Practical paper chromatography offers motivational learning opportunities, but relies on standard analytical grade papers or much less satisfactory alternatives such paper towelling.Using, for example, a mixture of CMY inkjet printer inks the card will produce a separation column up to 50mm in length in approximately 5 minutes. A whole class set of 100mm long spills can cost less than a single analytical grade equivalent spillApplications include: basic chromatography separation, forensic techniques, stain diffusion patterning, colour diffusion patterning, records of chemical reactions, fluid syphoning – i.e., how to empty a cup with a bent wick! The material is supplied in packs of 10 20x20cm sheets.Paper chromatographyIt is an analytical method used to separate coloured chemicals or substances.

sPaTulas

In laboratories, spatulas and microspatulas are small stainless steel utensils, used for scraping, transferring, or applying powders and paste-like chemicals or treatments. Many spatula brands are also resistant to acids, bases, heat, and solvents, which make them ideal for use with a wide range of compounds. A common type would be stainless steel spatulas, which are widely used because they are sturdy and affordable.available in:• 125mm• 150mm• 180mm• 200mm• 220mm

WaTch glass

A Watch Glass is a circular concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance and as a cover for a beaker. The latter use is generally applied to prevent dust or other particles enter-ing the beaker; the watch glass does not completely seal the beaker, so gas exchanges still occur. When used as an evaporation surface, it allows closer observation of precipitates or crystallization, and can be placed on a surface of contrasting color to improve the visibility overallavailable in:• φ70mm• φ90mm

Porcelain, Rim diam 216mmPestle height 190mm. Mortar and pestle is a set of 2 simple tools used since the stone age up to the present day to prepare ingredients or substances by crushing and grinding them into a fine paste or powder in the kitchen, laboratory, and pharmacy. The mortar is a bowl, typically made of hard wood, metal, ceramic, or hard stone, such as granite. The pestle is a blunt club-shaped object. The substance to be ground, which may be wet or dry, is placed in the mortar, where the pestle is pounding, pressing and rotating onto the substance, until the desired texture is achieved. Mortars and pestles have been used in cooking since prehistory; they are also frequently associated with the profession of pharmacy due to their historical use in preparing medicines. Mortars and pestles can also be used in chemistry for pulverizing small amounts of chemicals; in arts and cosmetics for pulverizing pigments, binders, and other substances; in ceramics for making grog; in masonry and in other types of construction requiring pulverization of materials. In cooking, mortars and pestle are especially used to crush spices and to make pesto, and certain cocktails, such as the mojito, require the gentle crushing of sugar, ice and mint leaves in the glass with a pestle.

Average results per class or per sample can be submitted to the IYC Global Database.2. Salty Waters – A saline solution (the “salty water” sample) is prepared and a known volume is placed in a Petri dish. The water is allowed to evaporate. The Petri dish is weighed before and after evaporation to find the mass of salt that was dissolved in the water. A natural water sample can also be used, such as sea water. Older learners can find the density and salinity of the sample. These results can be reported to the IYC Global Database.water Purification activities:3. Water Treatment – A dirty water sample is first aerated and then alum is added to coagulate solid matter (using large plastic vials). The water is filtered and the filtrate is treated with a hypochlorite solution to chlorinate it and kill any micro-organisms. This final chlorination step uses chlorine test strips to determine free available chlorine in the water. The minimum number of drops of hypochlorite that leads to 1 – 3 ppm chlorine after ten minutes is reported to the Global Database.4. Solar Still -A coloured saline sample is placed in the lunch box of the kit in the sun. Evaporation of the water occurs. The clear, colourless condensate is collected in a Petri dish to show that desalination using a solar still is one method of purifying water. A Solar Still yield can be reported to the Global Database.

Magnetic stirrer with thermometer stand and teflon stirrer. A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field. The reason is to cause a stir bar immersed in a liquid to spin very quickly, thus stirring it. The rotating field may be created either by a rotating magnet or a set of stationary electromagnets, placed beneath the vessel with the liquid. It is used in chemistry and biology where other forms of stirring, such as motorized stirrers and stirring rods, may not be viable for use.available in two sizes:• 200*120*90mm• 265*185*190mmeasy to use• Stepless speed adjustment 100-2000 rpm• 220V/50Hzoperation:1.Put the machine on worktable, and switch on power2.Turn on the stirring power clockwise and set rotating speed as needs.

Keep it in dry and clean room.A heating element, whose power may range from a few hundred to a few thousand watts, can also be incorporated to the stirrer to allow the reaction flask to be heated and stirred at the same time. The maximum reachable fluid temperature depends on the size of the flask, the quantity of solution to be heated, and the power of the heating element. Because of its small size, a stirring bar is more easily cleaned and sterilized than other stirring devices. They do not require lubricants which could contaminate the reaction vessel and the product. Magnetic stirrers may also include a hot plate or some other means for heating the liquid. A stir bar retriever is a separate magnet on the end of a long stick (usually coated with PTFE) which can be used to remove stir bars from a vessel.

distillation set with BunsenDistillation, or classical distillation, is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids). Dry distillation may involve chemical changes such as destructive distillation or cracking and is not discussed under this article. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components in the mixture. In either case, the process exploits differences in the relative volatility of the mixture’s components. In industrial applications, distillation is a unit operation of practically universal importance, but it is a physical separation process, not a chemical reaction.applicationsThe application of distillation can roughly be divided into four groups: laboratory scale, industrial distillation, distillation of herbs for perfumery and medicinals (herbal distillate), and food processing. The latter two are distinctively different from the former two in that distillation is not used as a true purification method but more to transfer all volatiles from the source materials to the distillate in the processing of beverages and herbs. The main difference between laboratory scale distillation and industrial distillation are that laboratory scale distillation is often performed on a batch basis, whereas industrial distillation often occurs continuously. In batch distillation, the composition of the source material, the vapors of the distilling compounds, and the distillate change during the distillation. In batch distillation, a still is charged (supplied) with a batch of feed mixture, which is then separated into its component fractions, which are collected sequentially from most volatile to less volatile, with the bottoms – remaining least or non-volatile fraction – removed at the end. The still can then be recharged and the process repeated.

These 16ml durable plastic test tubes are perfect for young scientists! Tubes are 125mm tall (with cap), 16mm diameter, with screw on cap (blue colour). A test tube, also known as a culture tube or sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top and closed at the bottom. Plastic Test tubes are usually placed in special-purpose racks.Plastic Test Tubes with cap in chemistryTest tubes intended for general chemical work are usually made of glass, for its relative resistance to heat. Tubes made from expansion-resistant glasses, mostly borosilicate glass. Chemistry tubes are available in a multitude of lengths and widths, typically from 10 to 20 mm wide and 50 to 200 mm long. The top often features a flared lip to aid pouring out the contents. A chemistry test tube typically has a flat bottom, a round bottom, or a conical bottom. Some test tubes are made to accept a ground glass stopper or a screw cap. They are often provided with a small ground glass or white glaze area near the top for labelling with a pencil. Test tubes are widely used by chemists to handle chemicals, especially for qualitative experiments and assays. Their spherical bottom and vertical sides reduce mass loss when pouring, make them easier to wash out, and allow convenient monitoring of the contents. The long, narrow neck of test tube slows down the spreading of gases to the environment. A plastic test tube with a cap is often used for temporary storage of chemical or biological samples.BiosciencesCulture tubes are test tubes used in biology and related sciences for handling and culturing all kinds of live organisms, such as molds, bacteria, seedlings, plant cuttings, etc.. Some racks for culture tubes are designed to hold the tubes in a nearly horizontal position, so as to maximize the surface of the culture medium inside. Plastic Test Tubes with Cap is not suitable for culture. Plastic test tubes are not suitable for boiling in high temperatures.

syrINges PK10

A syringe is a simple reciprocating pump consisting of a plunger (though in modern syringes, it is actually a piston) that fits tightly within a cylindrical tube called a barrel. The plunger can be linearly pulled and pushed along the inside of the tube, allowing the syringe to take in and expel liquid or gas through a discharge orifice at the front (open) end of the tube.Set of 10 pcs.available in :• 2ml• 5ml• 10ml• 20mlEach set includes 10 syringes of the same capacity.

BeaKer Tall form graduaTed

Most also have a small spout (or “beak”) to aid pouring, as shown in the picture. Beakers are available in a wide range of sizes, from one milliliter up to several liters. A beaker is distinguished from a flask by having straight rather than sloping sides. The exception to this definition is a slightly conical-sided beaker called a Philips beaker. The beaker shape in general drinkware is similar. Beakers are commonly made of glass (today usually borosilicate glass). A common use for polypropylene beakers is gamma spectral analysis of liquid and solid samples.construction and useStandard or “low-form” (A) beakers typically have a height about 1.4 times the diameter. The common low form with a spout was devised by John Joseph Griffin and is therefore sometimes called a Griffin beaker. These are the most universal character and are used for various purposes—from preparing solutions and decanting supernatant fluids to holding waste fluids prior to disposal to performing simple reactions. Low form beakers are likely to be used in some way when performing a chemical experiment. “Tall-form” (B) beakers have a height about twice their diameter. These are sometimes called Berzelius beakers and are mostly used for titration. Flat beakers (C) are often called “crystallizers” because most are used to perform crystallization, but they are also often used as a vessel for use in hot-bath heating. These beakers usually do not have a flat scale.The presence of a spout means that the beaker cannot have a lid. However, when in use, beakers may be covered by a watch glass to prevent contamination or loss of the contents, but allowing venting via the spout. Alternatively, a beaker may be covered with another larger beaker that has been inverted, though a watch glass is preferable.Beakers are often graduated, that is, marked on the side with lines indicating the volume contained. These marks are not intended for obtaining a precise measurement of volume (a volumetric flask would be a more appropriate instrument for such a task), but rather an estimation. Most beakers are accurate to within ~10%.

Volumetric flasks are used for precise dilutions and preparation of standard solutions. These flasks are usually pear-shaped, with a flat bottom, and made of glass or plastic. The flask’s mouth is either furnished with a plastic snap/screw cap or fitted with a joint to accommodate a PTFE or glass stopper. The neck of volumetric flasks is elongated and narrow with an etched ring graduation marking. The marking indicates the volume of liquid contained when filled up to that point. The marking is typically calibrated “to contain” (marked “TC” or “IN”) at 20 °C and indicated correspondingly on a label. The flask’s label also indicates the nominal volume, tolerance, precision class, relevant manufacturing standard and the manufacturer’s logo. Volumetric flasks are of various sizes, containing from 1 milliliter to 20 liters of liquid.

measurINg cylINder

A graduated cylinder, also known as measuring cylinder is a common piece of laboratory equipment. It is used to measure the volume of a liq-uid. It has a narrow cylindrical shape. Each marked line on the graduated cylinder represents the amount of liquid that has been measured.available in:• 10 ml• 25 ml• 50 ml• 100 ml• 250 ml• 500 ml• 1000 mlmeasuring:To read the volume accurately, the observation must be at an eye level and read at the bottom of a meniscus. The main reason as to why the reading of the volume is done via meniscus is due to the nature of the liquid in a closed surrounded space. By nature, liquid in the cylinder would be attracted to the wall around it through molecular forces. This forces the liquid surface to develop either a convex or concave shape. That depends on the type of the liquid in the cylinder. Reading the liq-uid at the bottom part of a concave or the top part of the convex liquid is equivalent to reading the liquid at its meniscus. The Measuring Cylin-der is made of glass borosilicate material.

It is the method of choice where economics and sample load do not warrant the use of automated equipment.measure raNgeThe method covers the range from about 0.05 to 1.0 mg NH3-N/L for the colorimetric procedure, from 1.0 to 25 mg/L for the titrimetric procedure, and from 0.05 to 1400 mg/L for the electrode method.summary of methodThe sample is buffered at a pH of 9.5 with a borate buffer in order to decrease hydrolysis of cyanates and organic nitrogen compounds, and is then distilled into a solution of boric acid. The ammonia in the distillate can be determined colorimetrically by nesslerization, titrimetrically with standard sulfuric acid with the use of a mixed indicator, or potentiometrically by the ammonia electrode. The choice between the first two procedures depends on the concentration of the ammonia

distillation set with BunsenDistillation, or classical distillation, is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids). Dry distillation may involve chemical changes such as destructive distillation or cracking and is not discussed under this article. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components in the mixture. In either case, the process exploits differences in the relative volatility of the mixture’s components. In industrial applications, distillation is a unit operation of practically universal importance, but it is a physical separation process, not a chemical reaction.applicationsThe application of distillation can roughly be divided into four groups: laboratory scale, industrial distillation, distillation of herbs for perfumery and medicinals (herbal distillate), and food processing. The latter two are distinctively different from the former two in that distillation is not used as a true purification method but more to transfer all volatiles from the source materials to the distillate in the processing of beverages and herbs. The main difference between laboratory scale distillation and industrial distillation are that laboratory scale distillation is often performed on a batch basis, whereas industrial distillation often occurs continuously. In batch distillation, the composition of the source material, the vapors of the distilling compounds, and the distillate change during the distillation. In batch distillation, a still is charged (supplied) with a batch of feed mixture, which is then separated into its component fractions, which are collected sequentially from most vol-atile to less volatile, with the bottoms – remaining least or non-volatile fraction – removed at the end. The still can then be recharged and the process repeated.

A Watch Glass is a circular concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance and as a cover for a beaker. The latter use is generally applied to prevent dust or other particles entering the beaker; the watch glass does not completely seal the beaker, so gas exchanges still occur. When used as an evaporation surface, it allows closer observation of precipitates or crystallization, and can be placed on a surface of contrasting color to improve the visibility overallavailable in:• diameter φ70mm• diameter φ90mm

Densimeter is an instrument for measuring density, especially of liquids.A Densimeter is a floating glass body with a bulb filled with a metal weight and a cylindrical stem with a scale. The hydrometer is immersed in the sample and the density of the sample can be read directly from the scale: The deeper it sinks, the less dense is the sample. If a hydrometer is immersed in a glass of water, it would sink deeper than it would in a glass of syrup because syrup is denser than water. This method is based on the Archimedes principleavailable in:• 800 – 900 kg/m3 – (0.80-0.90 gr/cm3)• 900 – 1000 kg/m3 – (0.90-1.00gr/cm3)• 1000 – 1100 kg/m3 – (1.00-1.10 gr/cm3)• 1100 – 1200 kg/m3 – (1.10-1.20 gr/cm3)• 1200 – 1300 kg/m3 – (1.20-1.30 gr/cm3)Price per item
