Disposable in-line filters of .45 microns and 700 cm2 of filtration area for metal sampling. They are specifically designed for the preparation of groundwater samples for the analysis of dissolved metals and to filter large volumes of cloudy groundwater.
Geopump peristaltic pumps are designed for water sampling. They operate by mechanical peristalsis, so the sample only comes into contact with the hose, preserving its integrity.
The Solinst peristaltic pump, designed for field use, operates by suction allowing vacuum pumping for the recovery of liquids or gases by pressure.
