Description

Use as a depth filter for larger totally filterable volumes. Sartorius Glass Fiber (GF) Pre-filters are made of borosilicate glass microfibers and are ideal for use as a pre-filter in clarification and sterile filtration. Available in a range of filter disc diameters.

The major use of the glass microfiber filter disc is as a depth prefilter in clarification and sterile filtration. As a prefilter, it is placed directly on top of a membrane filter. The prefilter diameter must be the one specified for the chosen holder; larger diameters will intrude under the sealing ring of the holder and cause leakage.
