FL4520

The use of a FL4520 filter paper is particularly recommended for foaming in the case of severely soiling samples. The filters are available in pack sizes of 100 pieces. The paper is made of chemically pure cellulose, is compatible with our measuring columns with an inner diameter of 40 mm without having to be cut to size and can be used with most liquids. The pore size is 12 to 15 µm, about the same porosity as our FL4504 glass filters.

Use of the paper filter requires two FI4501 sealing rings and an additional FI4504 sealing ring.
