Search the CONFOCAL archive at http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal We are setting up a new lab section and we need to select a vacuum pump to hook up to our vacuum plumbing.  We have a large manifold system that ties multiple vacuum taps together into one central location.  We plan on using a single pump to provide for the whole lab.  My concern is in vacuum stability as users open and close the tap, as well as capacity.  Should I be looking for a pump with a strong vacuum draw (low Torr number), or large displacement (liters/minute)?

Thanks,
