Syringe filters with different pore size ratings are suitable for different applications. For example, syringe filters containing 0.45 μm are typically used for HPLC sample preparation and 0.2 μm is used for UHPLC. In life science applications 0.1 and 0.2 µm pore sizes provide sterilization of buffers, culture media, and additives.
The material used for the filtration equipment/membrane is usually synthetic like Polytetrafluoroethylene (PTFE), Nylon, Cellulose acetate, Nitrocellulose etc. Electronic filtration units may involve the use of a motor or a pump to fasten the process. The pore size is crucial and varies depending on what matter or particle is separated/filtered.

Syringe filters for convenient filtration of small sample sizes through membranes. Cellulose acetate membranes are hydrophilic membranes that offer excellent flow rates. They are low protein-binding and provide superior chemical resistance to alcohols and oils.
Tisch Scientific Cellulose Acetate Syringe filters are built with attributes intended to bring the highest levels of dependability and purity to your applications. We provide a wide assortment of these wheel filters with membranes that produce separation and purification solutions for nearly all of your microfilter membrane needs.
The cellulose acetate membranes have improved solvent resistance, particularly to low molecular weight alcohols, and increased heat resistance. With high physical strength, the membrane filters can be used up to 180 DEG C, are suitable for hot gases, and can be sterilized by all methods without sacrificing the integrity of the membrane.†U.S
Membrane filtration is a process of filtering liquid by passing it through a membrane (made of cellulose acetate or mixed cellulose esters etc.) which has pores small enough to hold selected microbes and large enough to let the liquid pass through. The pore size can be from 0.22 to 0.45 micrometer.
To ensure all live and intact bacterial cells are removed, a 0.22µm pore size filter should be used. Typically, a 0.22µm cellulose filter, like cellulose acetate, cellulose nitrate or regenerated cellulose membranes, or 0.22µm synthetic membranes, like polyethersulfone or polytetrafluoroethylene filters, are used to remove bacterial cells.

Mar 09, 2021 · The filtration efficiency of the cellulose acetate membrane was lower than 91%, even at its highest quality factor. However, a maximum filtering efficiency of ca. 99% (filtering 100 nm particles) and ca. 97% (filtering 300 nm particles) was reported for polyvinyl acetate-based filter media.
