Sartorius 13400--49-49---K 49 x 49 mm Glass Microfiber Disc Filter

13400--49-49---K, 49 x 49 mm Glass Microfiber Disc Filter

The major use of the glass fiber filters is as a depth prefilter, placed directly on top of a membrane filter, whereby the prefilter diameter specified for the holder must be chosen. Larger diameters would intrude under the sealing ring of the holder and cause leakage. The standard type contains an acrlic binder. It has a high particle loading capacity. Serial filtration may be necessary for difficult-to-filter liquids such as serum.
