7.22 Vacuum System for Cell Harvesting:
Welch’s new portable oil-free general utility roughing pumps provide continuous, reliable vacuum that
your vacuum chamber, glove box, annular space and transfer line applications require. The pumping
mechanism is an economical twin head oil-free Wob-L® known for reliability and durability. These
rugged pumps handle 20,000 plus roughing cycles – from atmospheric to 5 Torr – before needing seal
maintenance.
The pumps come completely equipped and ready to use. An inlet trap to help prevent ingestion of fluids
into the pump, a dial gauge for continuous vacuum level monitoring, and a vacuum regulator to adjust
vacuum levels. Just plug it in and you’ re up and running.
