Vacuum filtration set with Rocker 300 vacuum pump


Our Rocker 300 vacuum filtration set is ideal for general filtration for microbiology, suspended solids testing and solvent purification. Included in this kit is 9 3/4′ of vacuum tubing. Save 10% by purchasing the kit.

Features :
No air pollution, maintenance free
Rocker series pumps are driven by Piston, without the need of lubricant, regular oil changes and maintenance; with no oil pollution.
Prote™ over­flow protection
Rocker series pumps are equipped with Prote™ ‑filter cartridge which can prevent a large amount of liquid from being sucked into the pump by negligence. It can also filter particles and moisture to prolong the service life of pump.
Thermal protection device
Every motor of Rocker series pumps has a built-in thermal protection device to shut off the pump automatically when overheated and then resume working when the temperature cools down.
