Difference between hydrophilic and hydrophobic filters
Difference between hydrophilic and hydrophobic filters. Hydrophilic filters are easily wet with water. Hydrophilic filters can be wetted with virtually any liquid, and are the preferred filters for aqueous solutions, as appropriate by compatibility. Once wetted, hydrophilic filters do not allow the free passage of gases until the applied

Syringe Filters for HPLC & Sample Preparation | analytics
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

Main Applications Of Hydrophobic And Hydrophilic PTFE
Jul 09, 2019 · Hydrophobic PTFE membrane filter can be used for atmospheric filtration detection, usually only for air filtration. Uncommon hydrophobic membranes can also be used to filter certain organic solvents, such as ethanol. In actual use, liquids that can pass hydrophobic filtration can also pass hydrophilic filtration. Therefore, it is recommended to
Membrane Filtration: Choosing the Correct Type of Filter | Cytiva
PTFE, polyvinylidene difluoride (PVDF), and RC are compatible with a wide range of solvents commonly used in HPLC while remaining low in extractables. We have compiled compatibility tables listing material resistance to common solvents, making them useful for quick reference.

UHPLC: Matching Filtration Technology to Particle Size - Sep
Sep 03, 2013 · Therefore, when an HPLC column has a packing size of 3 μm or smaller, a 0.2 μm filter should be used because a 0.45 μm filter may let particles through that will plug the column. For liquid chromatography systems using columns with packings larger than 3 μm, the filtration industry standard of 0.45 μm for syringe filters and mobile phase
