Membrane Filter - an overview | ScienceDirect Topics
In one report published in 1993, 0.4-µm pore diameter PTFE filters were used to establish that factors secreted by microglial cells are neurotoxic to neurons, whereas factors secreted by astroglia are neuroprotective. 11 In another example of coculture, neural stem cells that overexpressed a gene for hexosaminidase were cultured on porous

Syringe filter - Wikipedia
In scientific applications, the most common sizes available are 0.2 or 0.22 μm and 0.45 μm pores. These sizes are sufficient for HPLC use. The smallest known sterile syringe microfilter have pore sizes of 0.02 μm. Membrane diameters of 10 mm, 13 mm, 25 mm are common as well. Some syringe filters for small volumes may not resemble a wheel at all.
In-line Filters and Mixers for HPLC | Aijiren
Filters & Mixers for HPLC Even small amounts of particulates can clog your column inlet, causing high column backpressure, retention-time shift, resolution loss, and shorter column life. Aijiren offers high-pressure in-line filters designed to prevent blockages and extend column lifetime in any HPLC system, available in different dimensions and
Syringe Filters for HPLC and sample preparation | analytics
Pore Sizes and Pore Volumes. The filter size depends highly on the filtration volume. For small volumes (< 1 ml), syringe filters with a diameter of 3 mm are usually 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

Diagnosing & Troubleshooting HPLC Pressure Fluctuation
Jan 25, 2014 · Mobile phase pickup filters are often 10 to 20 um and connect to the bottom of the low pressure (e.g. Teflon) solvent lines in each bottle. If you use 316 Stainless steel filter (recommended for organic solvents), they should be removed, cleaned in an ultrasonic bath, rinsed and replaced monthly.

How to Select a Syringe Filter and How to Use it? (2020 Guide)
The pore size to be used is usually determined by the particle size to be eliminated. For example, for the purpose of filtering out particulate >0.2 microns in diameter, then choose a syringe filter with a 0.2 micron pore size. Another way to determine the micron size of columns, 0.45 um for >3 um, and 0.22 um for <3um.
Millex-GP Syringe Filter Unit, 0.22 µm, polyethersulfone, 33
Use them to filter protein solutions. The 0.2 µm filters are sterilizing grade. Larger pore sizes are for clarification and prefiltration. - Millex-MF filters feature mixed cellulose esters (MCE) membrane, which provides reliable, general purpose filtration of water or other aqueous solutions. The 0.2 µm filters are sterilizing grade.
