Filter housings are used in conjunction with cut disc membrane filters providing structural support and creating a seal around the membrane to prevent filtrate contamination. Reusable syringe filter holders are suited for filtering or clearing small amounts of liquid where a replaceable or removable filter is desired. Filter holders for vacuum and pressure filtration are available in a variety of formats and sizes to accommodate a range of filter diameters. Filter holder selection is dependent on the following criteria:
Reusable housings are constructed from either glass, metal, or plastic.
he filter holder diameter must match the diameter of the membrane filter. To minimize sample loss and reduce the risk of membrane fouling, sample volume should be considered when selecting a filter diameter. We offer filter holders with 13 mm, 25 mm, 47 mm, 90 mm, and 142 mm diameters.
Filter holders can withstand specific maximum pressures and have appropriate connections for use with either pressure systems or vacuum systems. Glass filter holders are designed for vacuum filtration. Stainless steel and plastic filter holders are designed for either vacuum or pressure filtration.
