Geotech Filters


The Geotech Disposable Inline Filter is a disposable filter capsule designed for field based groundwater sampling. All filters have a narrow pore distribution and high void volume that allows excellent liquid flow rates at low differential pressures.

The Geotech Disposable Inline Filter readily fits on 1/4" to 1/2" sized LDPE sample tubing with a specially designed sample tubing adapter. The tubing adapter is a hose-barbed fitting designed specifically to attach to the Geotech Disposable Inline Filter to any flexible sampling tube for inline sampling. Its sturdy wing-nut design ensures an easy, snug fit for continuous sampling integrity.

Micron pore sizes of 0.45, 1.0, 5.0 & 10.0 are available.
