Improving your Research with Vacuum-Driven Applications

Medicinal Chemists, Organic Chemists, Biochemists, Biologists, Molecular Biologists and other scientists rely upon Vacuum-Driven Devices to concentrate, dry, or filter their materials. Vacuum Pump Repair USA ensures that if your Vacuum pump system is not performing optimally; it can slow preparation of research-critical samples by as much as 50%-100%!

This can have a significant impact on time-to-market, or on your research paper productivity. Doesn’t it make sense to be certain that your Vacuum PumpSystems are operating at peak efficiency?

Conduct your Own Vacuum System Audit

Laboratories can benefit from periodic or even continuous monitoring of vacuum system performance. Welch’s inexpensive Digital Vacuum Gauge (1-760 torr) #1520B-01 and #1520K-10 are now available. Digital Millitorr Gauge 1525B-01 and 1525K- 10 are now available. Contact Vacuum Pump Repair USA for details on how to conduct to your own vacuum system audit.

Vacuum Pump Repair USA’s Vacuum System Audits typically take the following format:

  • A report page template is prepared, with as many copies as there are Systems.
  • The Auditor first measures vacuum achieved within the system. Manifolds should be measured at the terminus, while Rotovaps should be set up with vessels in place and measured at the valve connections near the condensers. Freeze Dryers have their own vacuum gauges, while Vacuum Ovens have an outlet port to connect with. The vacuum gauge can use tubing in the system or use appropriately sized tubing, clamped snugly onto one side of the vacuum gauge.
  • When you discover a vacuum pump system that is delivering poor performance, you must determine if the system is at fault, or if the pump’s performance is compromised. This is done by leak checking, a stepwise process where you first measure vacuum levels at the pump inlet, then at each connection, determining where the vacuum loss(es) are. Sometimes the losses come from multiple points. Once you determine the source of poor vacuum, you can rectify by vacuum pump repair or flushing, tightening vacuum tubing or replacing worn, cracked tubing, or cleaning manifold grease.
  • Cleaning vacuum manifold valves encrusted with chemically-damaged grease is the #1 way to improve Manifold Performance. Carefully tightening or greasing Freeze Dryer manifold valves/ports can help improve vacuum.
