Johnson Matthey has been manufacturing platinum and precious metal chemistry labware for 150 years. Alfa Aesar offers the full line of Johnson Matthey labware at competitive prices.
Platinum has properties that make it the ideal choice for many analytical applications. This metal resists the action of almost all acids and is unaffected by a wide variety of corrosive substances. It has a high melting point, a low heat capacity, and can be heated in air without any weight loss due to oxidation.
Zirconia grain stabilized (ZGS) platinum has been developed by Johnson Matthey to be resistant to grain growth, contamination and deformation at high temperatures. Through a process called dispersion strengthening, ZGS materials are produced by incorporating a fine insoluble phase dispersed uniformly throughout the platinum metal matrix.
Johnson Matthey also developed ZGS platinum 5% gold especially for non-wetting applications. It combines the workability and non-wetting properties of ordinary platinum 5% gold with the hot strength of rhodium platinum alloys, yet it is easier to fabricate and offers better stability. Its resistance to contamination makes it ideal for use in X-ray fluorescencesample preparation.
