Millipore. Millex-HP Syringe Filter Unit, 0.45 µm, polyethersulfone, 33 mm, gamma sterilized. A 33 mm diameter sterile syringe filter with a 0.45 µm pore size hydrophilic Polyethersulfone (PES) membrane. Comes in a pack of 50. MSDS (material safety data sheet) or SDS, CoA and CoQ, dossiers, brochures and other available documents.
Low hold-up volume helps you to recover virtually all of your sample after filtering. Tested for 100% membrane and housing integrity, eliminating concerns about fluid loss. Individually wrapped. Hydrophilic PVDF Membrane. Hydrophilic membrane binds far less protein than nitrocellulose, nylon or PTFE. Ideal for filtration of protein-containing aqueous, mild organic solutions and other pharmaceutical/biological/biotech solutions.
Membrane filters with a 0.45 µm pore size have long been recognized as the standard for growth of microorganisms. However, there is little published literature comparing the effects of different pore sizes on colony size and recovery. The 0.45 µm pore size is used to recover bacteria and other microorganisms from many samples and environ-
Sample filtration using syringe filters containing 0.45 μm (HPLC) or 0.2 μm (UHPLC) pore size membranes will also extend the life of chromatography columns by preventing particulate from blocking the flow path between the column packing. PVDF syringe filters offer excellent chemical compatibility, including aggressive acids and alcohols.
The common pore sizes are 0.45um and 0.20um and they're used for pressure filtration of culture media or injectables. I used to use them all the time in cell culture labs. They get the generic name of "syringe filters" because they have a luer-lock and you can lock them onto a syringe to force your media through one. No, they aren't self healing.

Pore Size Chart for Different types of filtration. The following chart shows the different pore sizes and molecules ideal for ultrafiltration, diafiltration, microfiltration, dialysis, and macrofiltration.
PTFE: Syringe Filter Diameter: 25mm (1 inch) pore size: 0.45um, IDEAL for making Liquid Culture as the jar can be inverted with NO leaks $2 ea. PTFE: Syringe Filter Diameter: 25mm (1 inch) pore size: 0.22 um, IDEAL for Grain Spawn Jars, allowing gas exchange
Syringe filter housings are matched based on composition and format, while membranes are matched to end applications by composition, filter diameter, and pore size. Syringe Filter Housing Formats. Covering a variety of end applications, our syringe filters are offered in three housing formats: classic, overmolded, and domed (Table 1).
SFCA (Surfactant-Free Cellulose Acetate with 0.2 µm and 0.45 µm pore sizes). SFCA is also a good media and serum filter. It is much cleaner (lower extractables) than CA membranes because it requires no wetting agent, but has slightly higher extractables and binding than does PES. Only Nalgene has SCFA in filter units and bottle top filters
