Geotech Disposable Sample Filter

The Geotech dispos-a-filter is a disposable filter capsule designed to perform in-line water filtration in the field and laboratory. The filters have a narrow pore distribution and high void volume that allow excellent liquid flow rates at low differential pressures and helps minimize sampling time. The 700 cm² dispos-a-filter readily fits on 1/4" to 1/2" sized sample tubing with a specially designed sample tubing adapter. The sample tubing adapter is a hose-barbed fitting designed specifically to attach to the dispos-a-filter capsule and any flexible sampling tube for in-line sampling. Each filter is ISO 9000 lot tested and traceable certified analysis for 68 metals and 7 anions in ppb range. Standard and high capacity models are available 0.45, 1.0 and 5.0 micron pore sizes.
