Vacuum pumps -

Laboport® vacuum pumps

• 100% oil-free transfer
• Maintenance-free
• Connection of pump heads in series for a higher vacuum, or in parallel for increased delivery
• For use with rotary evaporators, gel dryers, vacuum and filtration ovens

Water recirculation vacuum pump

Discover

Fume extraction and neutralisation system. This instrument is composed of a ''Scrubber'' unit that blocks the passage of acid condensation and neutralises the gases in an NaOH solution, and a water re-circulation pump that proportions a large vacuum throughput for sucking up fumes.

Vacuubrand vacuum pumps

Discover

• 100 % oil free
• Audible level: 45 dBA
• ME1C, ME2C NT and ME4C NT with PTFE membranes when chemical resistance is necessary
• PTFE sandwich membrane: one PTFE layer, one FPM payer, one fibre layer for excellent chemical and mechanical resistance
• Maintenance free

Chemical resistant Vacuum Pump

Discover

• Suitable for Vacuum filtration, Solvent purification, Solid-Phase Extraction (SPE), Gel electrophoresis
• All wetted parts of the Pump in contact with air are made of PTFE material which can resist most of corrosive gases
