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 fl uids 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.
