Glassy carbon is a unique material and exhibits properties entirely different from other forms of carbon with which one already has some high amount of familiarity. The evaporating dishes offered by SPI Supplies in SPI-Glas 22 Grade are plug-in compatible in many applications where presently only Pt evaporating dishes are being used. Their low economical cost, relative to platinum makes them especially in demand in days of shrinking research budgets. The very high density of the product literally prevents many molten materials from even spreading on the glassy carbon surface.

Why the SPI-Glas Glassy Carbon Evaporating Dishes are so Popular: The majority of our customers are using these glassy carbon evaporating dishes for wet decomposition procedures in analytical chemistry. Not only are they far lower is cost than platinum dishes, they are far less likely to "disappear", and they are more corrosion resistant and temperature resistant than platinum. For example, the SPI-Glas dishes are far more highly resistant to sodium peroxide. And of course, elements such as Fe, Cr, and Ni which would quickly alloy and ruin a platinum crucible won't have any noticeable effect on glassy carbon.
