2018/12/1 · The use of the syringe filtration method. Syringe filters with pore sizes of 0.22 μm and 0.45 μm (PVDF, Millipore, Ireland) were connected to 5-mL syringes. For each dilution, 2 mL were transferred into the syringes. The syringe plunger was depressed, and the filtrate was collected into tubes.

Sartolab® RF 50 vacuum filtration units are single-use units designed for the filtration of sample volumes of up to 50 mL. They are available either with an asymmetric 0.22 or 0.45 µm polyethersulfone membrane that provides the fastest flow rates and ensures lowest protein binding as well as low extractables.
Use Nalgene non-sterile syringe filters for sterilizing (0.2 micron) or clarifying gases or organic fluids, providing a barrier for sterile venting applications, such as benchtop fermenters, or protecting vacuum pumps from moisture. Air/Gas Filtration and Venting
Before 0.2 and 0.22 micron filters became standard, it was thought that filters with an absolute rating of 0.45 micron were thought to be sufficient to strain out even the smallest bacteria. However, the discovery of Brevundimonas diminuta, showed that there were still bacteria capable of passing through a 0.45 micron filter
