sorry again, wanted to emphasize that scientific supply house two stage "hi-vac" pumps are not in any way related to two stage refrigeration vacuum pumps. different animals. just wanted to make sure you knew the difference. get a mcmaster-carr catalog or a true scientific supply house catalog so you can see the difference, and be sure of the specs. scientific supply houses also supply special no offgass oil for these pumps. tom leech |
