Collection Filter Cassette
A Clear filter Cassette holds a 37mm filter. The desired filter type (typically of the GFA type) should be
conditioned and pre-weighed (if required) before being loaded into the cassette. Always handle filters with
care to prevent contamination or physical damage. It is recommended that even if gravimetric analysis is not
being performed a GFA filter (P102051) is still used to prevent particulate getting into the pump.
Note:
The filter cassette holder comes with one support pad to support filters. This is not in itself a
filter for gravimetric analysis. GFA filters should be purchased separately.
