How To Make a Simple Vacuum Test Pump Solution

Posted by Tim Collins on Aug 19, 2014 10:00:00 AM

Here is the problem: You aren't producing the vacuum you should, and you aren't sure where to start troubleshooting.  Often, the best place to start is the source of vacuum: your vacuum pump.  If your vacuum  pump isn't able to produce a pressure much lower than the vacuum level at which your chamber needs to be, then look no further.  If your process needs to run at 400 microns, and your vacuum pump can't deliver well below 400 microns, then start there.  Most 2-stage rotary pumps easily pump below 50 microns if they are working well.   Fortunately, testing your pump is very simple with a home made vacuum test pump. Below are instrucitons:
