Filter Holder for In-Line Filtration

The filter holder apparatus is suitable for both field and laboratory use and has a net filtration area of 130 cm². Only the sample medium comes into contact with the chemically inert PTFE; the rest of the unit is made of stainless steel, which makes it easy to clean in the field. With this filter unit, it is simple to remove soil particles from water samples.

This filter holder can be connected in-line to a peristaltic pump, a nitrogen-powered gas-lift pump, or a bladder pump. Vacuum filtration is also possible—any suitable vacuum pump may be used for that purpose. The device is compatible with 0.45-micron filters.

Note: Changing filter membranes can be difficult in windy conditions. If the appropriate filter membrane is used, chemically aggressive liquids and gases can also be filtered.
