Apiezon Grease, L
Specifications
Grease L is a petroleum hydrocarbon grease, containing no additives. Very low vapor pressure (at 20°C of 8x10-11 torr), high vacuum grade. Type L is widely used in the stationary phase of gas liquid chromatography, and may be used on all ground joints in a vacuum system (not for stopcocks). Its solubility is as follows: in Ethanol at 20°C-0.003%; 60°C-0.005%; 100°C-0.011%; 150°C-0.011%. Grease L softens and melts at about 47°C and it is not recommended for joints where temperatures exceed more than 30°C in use. Grease T is recommended for these higher temperatures.
