Defining a Pore Size and Sterile Filtering; 0.2 Micron vs. 0
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 in large quantities.
Syringe Filters for HPLC & Sample Preparation | analytics
Pore Sizes and Volumes. The filter size depends highly on the filtration volume. For small volumes (< 1 ml), syringe filters with a diameter of 3 mm are used for medium volumes (1-10 ml), 15 mm and for large volumes (> 10 ml) 25 mm. Common pore sizes for UHPLC and HPLC columns with small particle sizes (< 3 µm) are 0.2 and for columns with larger particle sizes (> 3.5 µm) 0.45 µm, respectively.

Membrane Filtration: Choosing the Correct Type of Filter
Differences between Hydrophilic Membranes and Hydrophobic Membranes. A hydrophobic membrane, such as polytetrafluoroethylene (PTFE) will resist any aqueous sample, creating back pressure. Although it is sometimes possible to overcome this back pressure with additional force, there is a risk of membrane rupture and incomplete filtration.
>PTFE membrane, Oleophobic PTFE membrane, PTFE dust collector
MS®PTFE hydrophobic membrane is used in a variety of liquid and air filtration applications. Material characteristics include broad chemical compatibility, excellent particle retention, easy handling and sealing, and compatibility with various sterilizing methods.
Filters in Dissolution Testing: Evaluation and Selection
UHPLC analysis (data not shown). When the hydrophilic PTFE membrane from vendor A (0.2 and 0.45 µm) were compared with polypropylene membranes from vendor B (same size), an increase in back pressure was observed for the mobile phase filtered through the polypropylene membrane (1500–2000 PSI). The hydrophilic PTFE

Syringe Filter, Membrane Filter FQA - filtration solutions
The common membranes used for gas/air filtration are our hydrophobic Polypropylene and PTFE Membranes. They both inhibit the flow of water vapors (hydrophilic) while allowing regular air molecules (such as oxygen) to pass. For the PTFE membrane the water intrusion pressure (which is inversely related to pore size) is greatest with the smaller
Hydrophobic PTFE Membrane Filters / Type 11806 | Sartorius
The main application of these membrane filters ist the filtration of air, gases and chemicals. PTFE membrane filters have an excellent chemical compatibility (pH 1 to 14), so that they are also used for the filtration of solvents and acids, to which other filter types are not resistant.
