Geotech Barrel Filter Holder

The Geotech Barrel Filter Holder is designed for on-site, manual filtration of surface or groundwater samples using a 0.45μm, 102mm diameter flatstock filter membrane. It is ideal for use in areas where a power supply is not available and in-line filtration is either impractical or impossible. Excellent option when standard, non-pressurized bailers are used for sample collection.
