2015 Vacuum Pumps Survey Results

Vacuum pumps are an essential piece of equipment and are used in a wide variety of processes in most laboratories. Over the past 25 years, it has become apparent that vendors have made significant innovative improvements to vacuum pumps, with important developments in high vacuum technology, corrosion resistance, vacuum control, and improvements in the efficiency and ecological impact of vacuum pumps.

vacuum pumps survey saysTop 6 Questions You Should Ask When Buying a Vacuum Pump

  1. What will you be using the vacuum for? Filtration needs modest vacuum. Evaporation requires deeper vacuum. Molecular distillation requires even more. Match the pump to the use.
  2. Can you use a dry (oil-free) vacuum pump? Oil-free vacuum pumps can support most lab applications. For the service advantages, choose a dry pump where possible.
  3. What is the pumping capacity at the intended vacuum level? Actual pumping speed declines from the nominal speed as depth of vacuum increases. The rate of decline differs among pumps.
  4. Do you work with corrosive media? Standard duty pumps have lower purchase costs, but corrosion-resistant pumps will have lower lifetime costs if working with corrosives.
  5. Should you invest in vacuum control? Electronics can improve reproducibility, protect samples, and shorten process times when specific vacuum conditions need to be maintained.
  6. What is the lifetime cost of operation? Include purchase cost, service intervals, servicing cost, pump protection (e.g., filters, cold traps), and staff time for operation.

Remote Control

Over the past few years that we’ve covered laboratory gadgets and apps, we’ve continued to see this area grow and become more accepted in the lab. While this year’s releases have added even more benefits to those working in the lab, the most recent trend has been all about helping laboratory professionals even when they are outside the lab.
