Laboratory Vacuum Pumps

How do you decide which pump is best suited for the task(s)?

Laboratory vacuum pumps can have a lot of different features, which makes them suitable for different jobs.
For example, “chemical duty” pumps have better chemical resistance, for working with organic solvents or corrosive substances. Others can apply pressure as well as vacuum, while some are oil-free to reduce maintenance requirements and the risk of contamination. Some pumps are available with a regulator or gauge to accurately monitor the vacuum, then there is the flow rate and ultimate vacuum to consider, to ensure the pump is powerful enough for the job. In addition, there are four main types of vacuum pumps to choice from:

  • Rotary Vane
  • Diaphram
  • Combination pump
  • Scroll

At Camlab we supply rotary vane and diagram pumps from two main suppliers KNF and Welch by Garnder Denver. Both these types are widely used in laboratories. Below we have provided some common uses example of pumps.

But first, let us look at some key points to consider:
