polypropylene vented cap has a 0.22µm (PTFE) hydrophobic membrane to allow gas exchange while preventing contamination. They have a liner-less plug seal design for efficient sealing. They are autoclavable at 121°C.
Slide 1 of 3. Syringe filters are single-use, membrane-based devices used for the removal of particulate impurities from liquid and gas samples prior to analysis by methods such as HPLC, ion chromatography, gas chromatography, ICP, and dissolution testing. Proper filtration of samples improves the quality and consistency of analytical results
Whatman GD/X syringe filters are the perfect solution for samples with high viscosity or samples that contain particles. Four filter layers decrease clogging and therefore filter exchange during processing is avoided. These filters allow 3 to 7 times higher throughput than traditional types. Product Specification: Membrane: CA. Filter diam.: 25mm.
Jun 02, 2006 · Immediately after the pore water was collected, 15 mL of the sample was injected through a 15-mm diameter Whatman GF/A syringe filter into a 37-mL sealed serum bottle containing nitrogen gas and 2 g KCl as an inhibitor of microbial activity [Striegl et al., 2001].
Syringe filters GD/X® Pack of 1500 Whatman GD/X syringe filters are the perfect solution for samples with high viscosity or samples that contain particles. Four filter layers decrease clogging and therefore filter exchange during processing is avoided. These filters allow 3 to 7 times higher throughput than traditional types. Membrane: RC
3T -(0.2 micron) (8″ X 5″ X 19″) 2.2 Mil Polypropylene 3B -(5 micron) (8″ X 5″ X 19″) 2.2 Mil Polypropylene. About the Filters: T Filter – 0.2 micron provides highest filtration and least gas exchange. Best for grain spawn. A Filter – 0.5 micron provides high filtration while allowing more gas exchange than T filters. Good for

We carry PTFE syringe filters for making liquid culture lids in both 13mm and 25mm diameters. We also offer the largest selection of synthetic filter discs online. Our synthetic filter discs provide for contaminant-free gas exchange on spawn jar lids. All of our synthetic filter discs have a pore size of 0.3 microns.
Syringe filters with different pore size ratings are suitable for different applications. For example, syringe filters containing 0.45 μm are typically used for HPLC sample preparation and 0.2 μm is used for UHPLC. In life science applications 0.1 and 0.2 µm pore sizes provide sterilization of buffers, culture media, and additives.

Laboratory filtration is the physical or mechanical separation of particles or components within a sample medium such as a liquid or gas by introducing a medium through which only the gas/liquid can pass. Therefore a size exclusion that will separate the starting sample into two fractions. One fraction (permeate/filtrate) will be the clarified
