0.45μm 47mm PES Filter Membrane Discs Non-Sterile For Microbiological Analysis
PES membrane disc filter is a type of filter that has been cut into circles and ready for use. The disc filters are constructed of polyethersulfone with low-protein-binding, low-extractable and hydrophilic properties. These characteristics enables the disc filters to provide fast flow rates and high throughput when filtering media, buffers, and other filtrates, making them a recommended solution for a wide variety of aqueous filtration applications. PES filter membranes are particularly useful in microbiological and life science applications.
PES disc filters are available in a wide of range of porosities: 0.1μm,0.22µm,0.45μm, 0.65μm, 0.8μm,1.2μm,3μm,5μm etc. The 0.22µm porosity is designed for sterilization and complete bacterial retention, while the 0.45µm porosity is intended for particulate removal and clarification. Industry standard diameters of 13, 25, 47, 90, 142, 293mm all available.
The PES membrane discs offered by XINNA are non-sterile, but they can be autoclaved and gamma sterilized to meet specific requirements. If you have unique needs that require a different level of sterilization, please don't hesitate to contact us. As a manufacturer of membrane filters, we can also customize the pore size and diameters to suit your needs and provide tailor-made samples for approval in a very short period of time.

Application
These PES membrane discs are typically used in applications where high-purity liquids are being processed, such as in chemical manufacturing or biomedical research.The PES filters work by allowing fluid to pass through the membrane while trapping any particles that are larger than the pores in the membrane. The trapped particles can then be removed from the fluid using a vacuum or other means, depending on the specific application. Their common uses include,
