Geotech In-line Acrylic Filter Holders
& Barrel Filter Holder

Geotech In-line Acrylic Filter Holders are specifically designed for on-site, rapid filtration of surface or groundwater samples through large diameter flatstock filter membranes.

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.

Acrylic Filter Holders

  • 102 mm and 142 mm filter membrane sizes
  • Nylon or stainless steel bolt versions

Barrel Filter Holder

  • 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.
