Membrane Types View All Lab Filters Glass Filter Grades Cellulose Nitrate (CN) membrane is the most popular membrane used in analytical and laboratory filtration. CN membrane has excellent wetting properties and gives fastest flow rates with aqueous solutions.
Cytiva. a PTFE membrane that provides highly efficient filtration in a very small area. Capsules with 1.0 µm pore size are supplied with a solvent-resistant polypropylene prefilter for extended life and are intended for use with highly contaminated solutions. The 0.05 and 0.1 µm filter
the absolute rated membrane cartridge filter The Memtrex absolute pleated cartridge filter family features a membrane as filtration media. The Memtrex family covers a wide range of applications thanks to multiple hydrophilic and hydrophobic media such as polyethersulfone (PES), nylon 66, polypropylene (PP), polytetrafluoroethylene (PTFE), and polycarbonate track-etched (PCTE).
Final Membrane Filters The highly uniform, porous structure of these sterilizing grade membrane filters provides highly effective filtration by retaining parti-cles and bacteria absolutely, with 100% retention. The Sartorius product range of sterilizing grade filter
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
Solvent Filtration Membrane found in: Solvent Filtration Disposable Vacuum Bottle Top Filters, Semi-Prep Solvent Filtration Frits, Magna PTFE (Teflon).. Using 47mm membranes for filtering corrosive solutions, particulate removal from HPLC solvents, and filtration analysis with solid phase extraction disks.
membrane filter to prevent rapid plugging or use a 2-in-1 filter that has a built-in pre-filter in a single housing. 3. Choose the membrane type based on the solvent that you want to filter. Filter Types All filter inlets are female Luer-compatible, have inertdiameters.
Cobetterlab Membrane filters are offered in the most popular membrane materials for various applications. Such as Mixed Cellulose Esters, Cellulose Acetate and Nylon are reverse phase solvent cast membranes, where controlled evaporation or removal of the
0.22 μm hydrophilic PTFE membrane filter bubble points are above or equal 0.1MPa and 0.06MPa respectively, diameters ranging from 13mm, 25mm, 47mm to 90mm, 142mm, 293mm. Hydrophilic PTFE membrane pore size is 0.22μm, 0.45μm and chemical compatibilities are superior to aqueous, organic solvents and mixed solvents.
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. Moreover they can be used to filter aqueous solutions as well, but because of their hydrophobic characteristics, they must be pre-wetted with ethanol or methanol before the filtration of aqueous media
S series (Organic solvents) S series are installed Teflon filter (polytetrafluoroethylene, PTFE) with strong resistance to organic solvents, acids and alkalis. They are best suited for prefiltration of samples with aggressive organic solvents such as chloroform and tetrahydrofuran.
Ensuring the correct filtration membrane has been selected from different types of filter materials is often overlooked in routine laboratory sample filtration. Here, we explore different filtration properties and how to take a preventative—rather than reactive—approach
* For samples with laden particulate that are difficult to filter, it is best to use a syringe filter with a glass fiber pre-filter over the membrane. These are available in GHP and Nylon. Choice: Membrane 0.45 µm GHP Acrodisc in 4 mm or larger. You can also use the
