HPLC Syringe Filters available in two sizes: 13 mm and 30 mm; Two pore sizes: 0.2 µm and 0.45 µm; Glass Fiber syringe filters available in 1.2 and 0.7 µm; Available in 7 color
Dec 07, 2020 · The main selection criteria for your syringe filter membrane is solvent compatibility and application (specifically, if you are concerned with protein binding). Nylon membranes are used for general laboratory filtration of HPLC samples prior to injection. Nylon is solvent resistant, exhibits lows extractables, and is compatible with both
Syringe Filters. Syringe filters are attached to the end of a syringe to remove particles from a sample prior to analysis. Filtering liquids, the single-use devices force liquids through the filter either when fluids are initially drawn or delivered. Circular shaped in diameters that fit common syringe sizes, the cartridges remove fragments
Hold the syringe with the filter pointing up and “top off” by pushing a few drops through the filter. Place the filter tip over the collection container and push the sample through a syringe filter by applying gentle positive pressure. To purge the syringe filter and maximize sample throughput, remove the filter from the syringe and draw air into the syringe. Then reattach the filter and push the plunger to force some of the air through the filter.
CHROMAFIL Syringe Filters Feature: Different membrane types to meet multiple filtration applications. Low extractable, sonic welded, leak-free polypropylene housings. Fast flow geometry for minimized back pressure during filtration. Very low hold-up volumes for maximum volume recovery. Certified clean for HPLC and UPLC analysis.
Sterile Syringe Filters. Sterile Diamond® PureFlow™ syringe filters satisfy requirements of life science applications for sterilization of solutions or clarification of biological fluids. Sterile filters include a polypropylene microfiber pre-filter layer to improve filtration of particulate-laden fluids that are difficult to filter with
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

A variety of membranes are available to meet your needs: Polyethersulfone (PES) – low protein binding and faster flow rates; surfactant-free cellulose acetate (SFCA) – lowest protein binding; polytetrafluorethylene (PTFE) – chemical resistance; regenerated cellulose (RC) – best choice for DMSO compatibility; Nylon (NY) – hydrophilic, surfactant-free, and lowest extractable. 100%
Syringe filters (or wheel filters) are a single-use filter cartridge locate at the end of a syringe. Syringe filters can have luer lock fittings for a secure fit to the syringe. Choose from our wide assortment of filters to suit your application. Syringe filters come in a variety of membrane types. When selecting a syringe filter, be

Feb 17, 2020 · A PTFE syringe filter is an ideal choice for filtering and de-gassing chromatography solvents. With proper pre-wetting (commonly used alcohol), aqueous samples are also compatible. When using air-vents, these syringe filters are capable of stopping moisture from passing through. Workable pH range: 1-14.
Supplier: Pall Laboratory. These 25 mm syringe filters offer an available prefiltration layer and wide choice of filter media. Wide range of filter media available. Available in 0.2 µm for UHPLC applications. Available with pre-filter for difficult to filter samples. Color coded for easy identification. Polypropylene housing with female Luer
Syringe filters are sterilized by gamma irradiation, preventing the contamination risk that can result from ethylene oxide sterilization. They are individually blister packed to ensure sterility during storage and handling. Replacing a syringe filter midway through the process may lead to contamination, spills, and workflow disruption.
How To Use a Syringe Filter. Fill the syringe with the solution to be filtered. Fasten the filled syringe to the FLL inlet of the syringe filter with a twisting motion. With the outlet pointed upward, gradually apply pressure to the syringe plunger to initiate flow. Continue thumb pressure until all the air in the device is displaced with
