Apiezon® L Greases

Description

Grease L is a petrolatum hydrocarbon grease containing no additives. It is a good, general purpose, high vacuum grade with an estimated vapor pressure at 20 °C of 8 x 10^-11 torr. It is widely used as the stationary phase in gas-liquid chromatography, and may be used on all ground joints in a vacuum system where it is essential to have a grease with good lubricant properties combined with an exceptionally low vapor pressure. Grease L softens and melts at about 47 °C and is not recommended for joints likely to warm to over 30 °C. Greases T and H are recommended for these higher temperatures.

Specs

* Over temperature range 20 to 30o C
(a)  Greases AP101 and H do not melt at high temperatures and consequently many of the above physical properties cannot readily be measured
(b)  Specific heats of Greases L, M, N and T cannot be measured as their fusion peaks are too close to room temperature.

Precautions

PRECAUTIONS: Apiezon Products - Health and Safety

Apiezon products have been widely and safely used in vacuum distillation apparatus in both industry and laboratories for a number of years. As a result they should not present a health hazard assuming normal standards of industrial hygiene and safety are followed in their handling.

All Apiezon products are bases on petroleum products of a low order of acute toxicity. However, certain individual develop a rash after repeated contact. Therefore, it is recommended that gloves be worn to handle Apiezon. If Apiezon material is inadvertently in contact with the skin, wipe the area carefully, then cleanse thoroughly using a mild soap. Should any Apiezon products be heated for application, vent the fumes and avoid breathing the warm vapors.

In terms of explosion and fire, Apiezon products are considered non-hazardous.
