• 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
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.
• 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
• 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 • Without the need of lubrifiant, regular oil changes and maintenance; with no oil pollution • Built-in thermal protection device to shut off the pump automatically when overheated and then resume working when the temperature cools down • The Chemker 411 pump is equipped with a moisture trap and a valve for vacuum adjustment
• Suitable Filtration for microbiology test, Vacuum filtration, Air sampling and Suspended solid test • With vacuum regulator to adjust vacuum • Driven by Piston, without the need of lubricant, regular oil changes and maintenance • Equipped with Prote™ overflow protection which can prevent a large amount of liquid from being sucked into the pump (Excluding 800 and 810 models) • Equipped with filter cartridge in air inlet to filter particle and moisture to prolong the life of pump(as well as in air outlet for 430 and 600models) • Built-in thermal protection device to shut off the pump automatically when overheated and then resume working when the temperature cools down
• Small footprint • Integrated speed control • 100% oil-free for contamination-free transfer, discharge and compression
Pumps N 820 G and N 840 G: • Expandable: separators and/or capacitors can be purchased separately and easily installed • 3 colour status display: on / pause / error • Internal atmosphere according to ATEX II 2/-G IIB+H2 T3 • High compatibility with steam and condensation • Air ballast
• 100% oil-free, abrasion-free, no wearing parts • Frictionless operation: no particle generation • RS485 interface with Modbus RTU protocol for remote control of the pump • Noise level: 55 dBa • 10C version for increased chemical resistance
