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 inert polypropylene or polycarbonate housings and come in four diameters. 30 mm filters
Syringe/Disc Filters The smaller conventional Corning® syringe disc-type filters (4, 15, 25, 26, and 28 mm diameter) are used with syringes which serves as both the fluid reservoir and the pressure source. They are 100% integrity tested. The HPLC-certified non-sterile syringe filters are available with nylon, regenerated
Pall’s sterile syringe filters are available with a variety of high-performance membranes to suit application requirements: Fluorodyne® II Membrane - For high flow rates and low protein binding. Not recommended for use with some ethers. Supor® Membrane - For high throughputs, fast filtration, and low protein binding.
1) Syringe filter housings are manufactured from solvent-resistant, low-extractable polypropylene resins specifically selected for wide compatibility with common HPLC sample matrices. 2) Solutions at temperatures up to 100°C can be filtered using syringe filters.
Intro. There are so many solvents and syringe filter/membrane materials that it can be tough to remember which combinations are safe and which are corrosive. These tables show five common syringe filter materials -- Cellulose Acetate (CA), Nylon, PES, PTFE, and PVDF -- and their compatibilities with 75 common solvents.
Sample filtration using syringe filters containing 0.45 μm (HPLC) or 0.2 μm (UHPLC) pore size membranes will also extend the life of chromatography columns by preventing particulate from blocking the flow path between the column packing. PVDF syringe filters offer excellent chemical compatibility, including aggressive acids and alcohols.
addition, solvent-membrane compatibility requires additional consideration of filtration-specific factors. None of these published compatibility guides, for example, monitors the solvent’s ability to wet a membrane or increase extractables. 4. This table does not consider solvent safety issues.
A syringe filter (or wheel filter) is a single-use, membrane-based device used for the removal of particulate impurities from small (≤ 100 mL) liquid samples ( Figure 1 ). Selected based upon the desired end application, disposable syringe filters are commonly used in labs for fast and efficient filtering, material purification, or even
POREX® Dialysis filters provide containment of dialysis system media, such as those utilizing bicarbonate concentrates in disposable and dry formulations. Dialysis fluid is prepared according to individual patient needs and POREX® filters, both inlet and outlet, help regulate concentrate bag fluid flow and back pressure,
Catalog number: CH2225-NP. Use Aijiren Tech™ Choice™ PTFE Hydrophobic Syringe Filters for filtration of aggressive organic, highly basic or hot solutions and as transducer protectors. They can filter aqueous solutions after pre-wetting with an alcohol. These syringe filters provide cleaner sample extracts by removing interfering
Pore size ratings are usually stated in Micrometers (μm). 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.
Solutions containing a known concentration of either 0.24 μm or 0.5 μm particles were filtered using 0.45 μm hydrophilic PTFE syringe filters and particle concentration in the final filtrate was measured to determine the average particle retention for each filter.
Syringe Filter Housings Syringe filter housings are manufactured from solvent-resistant, low-extractable polypropylene resins specifically selected for wide compatibility with common HPLC sample matrices. Solutions at temperatures up to 100°C can be filtered using syringe filters. Syringe filters can be sterilized by autoclave at
These Corning syringe filters have acrylic copolymer housings, female luer lock inlets and male luer slip outlets. Polyethersulfone (PES) membranes provide the fastest flow rates, low protein binding and low extractables. 100% integrity tested, sterile and certified nonpyrogenic and noncytotoxic.
