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.
