Features: 

• BVA Vacuum Pump Oil is the gold standard in vacuum pump care.
• For use in any vacuum pump, BVA is extremely pure and non-detergent. It is hydro-processed, meaning it goes through a series of catalytic steps rendering the oil extremely refined, more viscous, and more stable.
• The result is clear mineral oil which will alert you to contamination sooner as it becomes cloudy or milky. In extreme temperatures, the oil will be more resistant to contaminants.
• We still recommend, however, that the oil be changed after every evacuation for maximum performance and pump efficiency.
• The best test to see if your oil is contaminated is through a micron gauge. With a leak-free system, if your DV-22N micron gauge is still not reading a deep vacuum, oil is too contaminated and should be changed. If the micron gauge pulls down to about 50 microns the oil is good.
