The model 410 Peristaltic Pump operates to the suction lift limit, allowing vacuum pumping or pressure delivery of liquids or gases. It is ideal for vapour 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 – for portability, add a 12V battery holder. The pump can deliver from 40 ml/min to 3.2 litres/min. It is water resistant, has a handle and one easy-access control.
