Filter Holders
Barrel Filter Holder 2.4 Liter
The Barrel Filter is an acrylic pressure filtration
unit designed for the convenient and rapid filtration of
water samples prior to chemical analysis. The Barrel
Filter Holder is designed for on-site filtration where
power is not available and in-line filtration is not
practical. It uses a 0.45µm, 102 mm filter membrane. It
is lightweight, compact, rugged and is particularly
convenient for field use. It is recommended for
filtration of samples at the time of collection. The
application of moderate pressure from a hand pump
permits rapid filtration of all but the most excessively
turbid samples.

The In-line Filter Holders are specifically designed
for on-site, rapid filtration of water samples through
large diameter flatstock membranes. While able to be
used in-line with any dedicated or portable pumping
system, they are most often used with the Geopump™
Peristaltic Pump. The sample can be directly pumped from
any surface water source or monitoring well. The sample
then enters the filter holder and flows into a
collection container placed beneath the discharge
fitting.
