BOLA Sampling Pumps Made of polypropylene and PTFE. A pull on the ball handle produces a slight vacuum in the sampling bottle. Due to this vacuum, the sample is sucked into the sampling bottle. Both glass bottles and plastic bottles with a GL 45 thread can be used as sampling bottles. The pump provides universal chemical resistance since the sample is only exposed to a PTFE tubing. Abmessungen: Thread for connection GL 18 For bottles with a capacity of ml 100 - 2.000 Suction lift of water max. m 4,5
