TURN YOUR THEORY INTO REALITY We are specialist suppliers of advanced materials and equipment for innovative research, taking your ideas from lab-scale to production. We custom manufacture to exact specifications, have expertise in sourcing niche products through our trusted network of worldwide suppliers and offer an on-line range of standard stock products including consumables available for immediate despatch.

We offer a wide range of platinum products and accessories for organic and inorganic analysis.

All labware products can be supplied in platinum, platinum-gold, platinum-gold-rhodium and other precious alloys, available upon request.

Platinum crucibles and accessories are manufactured in pure platinum or in alloys with Gold, Rhodium, Iridium, Palladium and other precious metals, available for the below processes and within the following forms:

• XRF analysis• Microanalysis• Burning• Evaporation (where resistance to high temperatures and to chemical attack by acids

and fusion mixtures is required)• Mini-crucibles• Moulds (with or without pouring lips, pins on supporting ring, reinforced rims)• Basting moulds• Boats• Tongs with shot-blasted platinum shoes• Mixers• Triangles• Electrodes

The capacities and shapes of our crucibles and dishes are suitable for the various types of automatic and semi-automatic analysis machines on the market.

Services:

• Platinum coating of non-precious metals crucibles• Custom requirements: from development to production through to after-sales care, we

can supply finished products to exact specifications.• Reclaim: we can reclaim platinum contained in used crucibles.
