Masterflex Peristaltic Pumps operated by mechanical peristalsis, so the sample only comes in contact with the tubing. This allows for sample integrity as well as easy cleaning and replacement. With the optional stainless steel tubing weight, tubing can be lowered to a specific depth without curling or floating on the surface of water. GeoPumps operate from any external 12VCD or 120VAC power source. These units have one pumping station which can be piggy-backed for multi-station pumping.
