The 410 Peristaltic Pump operates to the suction lift limit, allowing vacuum pumping or pressure delivery of liquids or gases. It is ideal for vapor or water sampling from shallow wells and surface water. The Pump has reversible flow, a variable pumping rate and allows the use of either 3/8" or 5/8" (10 mm or 16 mm) silicone tubing. The pump head design makes it easy to change or replace the tubing. The power cable clips to any 12 volt DC supply. It can deliver from 40 ml/min to 3.2 liters/min. The pump is water resistant, very compact and simple to use, with a handle and one easy-access control.
