Product details
Watson-Marlow 100 and 300 Series Laboratory Peristaltic Pumps
Watson-Marlow peristaltic pumps move liquid by squeezing a flexible tube, so the liquid touches only the tubing and there are no valves, seals or glands in the fluid path.
The 100 series are small, stackable pumps for flows up to 190 ml/min, useful where space is tight, such as in cleanrooms, laminar flow cabinets and biosafety cabinets. The 300 series (323) are benchtop pumps with a choice of pumpheads, from 5-channel microcassettes to high-flow heads, for flows from 2 µl/min to 2,000 ml/min. CSI Labshop can supply Watson-Marlow pumps in Malaysia.
