Search the CONFOCAL archive at http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal What can I use for the buffer tank?  Is there a particular style, or can I just stick any old pressure tank on the line and draw a vacuum reservoir on it?

Thanks,

Craig

Craig,
 
             The first thing you should be looking at is a big buffer
tank to even out the fluctuations.  Having a lower Torr than you
need will do very little for you - the difference in the total mass
of air in a chamber at 0.1T vs 1T is tiny.  The displacement is
the key thing - it must be able to handle everyone wanting it at
once.

Subject: Vacuum pump advice?

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,

Craig
