Description
Excellent lubricants
High purity, low vapor pressure – non-contamination in analysis
The working temperature range of each grease is dependent on the grade that is used
Easily applied, easily cleaned off
Silicone free. This benefits scientific users because the risk of sample contamination and consequently the risk of interference in analytical techniques such as infra-red or mass spctrometry, etc. is avoided
Approved by NASA and NATO
