Features & Benefits

PTFE wetted parts are highly resistant to corrosive gases.
Diaphragm-based pump is low maintenance and virtually pollution free.
Quiet, low-vibration units keep disturbances to a minimum.
Built-in thermal protector automatically shuts off pump if it overheats and then restarts it once the unit is cool.
International CE and CSA certification.
Applications include vacuum filtration, gel electrophoresis, solid-phase extraction, solvent purification, and general use. (Not intended to evacuate air canisters.)
