Range:
This grease does not melt and is been composed for lubrication and sealing of
glass and wrenches in high vacuum systems with outstanding stability.
GLASSWARE:
Glass is an organic mixture of metal oxides fused together at high temperatures,
which upon cooling, solidifies into the clear, rigid, non-crystalline, versatile
material known widely across the globe
Borosilicate glass has a very high resistance to attack from water, acids, salt
solutions, halogens and organic solvents. Only hydrofluoric acid, hot concentrated
phosphoric acid and strong alkaline solutions cause appreciable corrosion of
the glass.
Borosilicate glass has excellent thermal properties at both high and low
temperatures. The maximum recommended working temperature for laboratory
glassware manufactured is 500ºC (for short periods of time only). Special care
should be taken at temperatures above 150ºC to ensure both heating and cooling
is achieved in a slow and uniform manner.
