PLATINUM LABWARE

We offer high quality platinum products backed by a team of experienced chemists and metallurgists. These products include platinum crucibles used for various fusion or melting processes in the analytical lab and platinum dishes for casting of glass bead in fusion application. Our extensive range of Platinum & Zirconium labware is manufactured in standard configuration. In addition to that, we can also assist in the manufacture and design of specialized platinum products.

The use of precious metals is still essential because of their good chemical resistance to aggressive media. Precious metals remain stable even at high temperatures. With our recycling program you can give your old labware to us to recover your investment or you can recast new labware with your old metal. Our refining team is dedicated to helping customers get the most out of their precious metals. Damaged laboratory ware, like crucibles, moulds, thermocouple wires, foil, etc. can be sent to us for refining.

Common Metals for Labware

Metals which are to be used for laboratory apparatus need to have the following characteristics:

Our Products

Platinum and its alloys possess these qualities and are therefore the most widely used metal for analytical laboratory apparatus. Properties of platinum and some common platinum alloys are briefly discussed here:

Platinum

Is the best known and least rare of the platinum group metals. Its high melting point, 1773 degrees Celsius, …
ductility and excellent resistance to chemical attack by acids makes it very suitable for laboratory ware.

Platinum 10% Rhodium

This alloy has a melting point of 1850 degrees Celsius, it has greater hardness and higher strength … than other platinum alloys. It is capable of maintaining its shape under the hottest furnace conditions.

Platinum 5% Gold

Universally accepted material of choice for crucible and casting moulds for spectrographic analysis …
by x-ray fluorescence (XRF). This alloy has higher temperature strength than pure platinum and has a “non-wetting” property, which results in easy removal of the sample after fusion and allows for many reproducible assays.

Platinum Gold Rhodium (90/5/5)

This alloy combines the “non-wetting” property of the Pt/Au alloy and the extra strength and durability of Pt/Rh alloys.

Platinum 3.5% Rhodium

The rhodium alloys have higher hardness and high temperature strength making it suitable for more aggressive conditions.

Gold

Gold can be used in labware. Its most common application is for hydrofluoric acid treatment of siliceous materials.

Silver

Pure silver can be used for fusion with alkali hydroxide.
