Cartridge Filter. Cartridge filters are available in various lengths and diameters as well as construction materials (woven, nonwoven, and membranes). The flow is outside-to-inside. Therefore, these filters require a strong core to be able to handle the increased pressure differential during operation.
High rate filters, which operate at three-to-four times the rate of rapid sand filters, use a combination of filter media, not just sand. Media combinations are generally sand and anthracite coal. Multi-media or mixed-media filters generally use sand, anthracite coal, and garnet.
Puradisc syringe filters combine premium quality and economy. They are ideal for the quick, efficient filtration of samples up to 100 mL volume. Puradisc filters are produced from pigment-free polypropylene or polycarbonate with standard inlet (female luer lock) and outlet (male luer) connections (unless otherwise stated).
Polypropylene syringe filters are the optimal choice for analytical sample preparation. Pall’s polypropylene non-sterile syringe filter housing is chemically resistant to harsh solvents, is low in extractables and low in API and biomolecular compound adsorption. Chemical compatibility is a critical consideration when selecting a syringe filter.
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
Minisart ® Syringe Filters: The Industry Leading Syringe Filter - Turning Science into Solutions. Sartorius offers Minisart ® syringe filters for a wide range of applications, including sterile filtration. Our filters are clean and safe as they are almost free of leachables and exractables and ultralow absorption properties.
Filtration and Water Circulation Clean, sparkling water is the result of a healthy, thriving aquarium. The secret to maintaining optimum water quality in any aquarium is three-stage filtration: mechanical filtration, chemical filtration and biological filtration.

Mar 04, 2018 · 1.Get the most appropriate filter to use. 2.Draw 1ml of air followed by your sample in a sterile syringe. 3.Eject 1ml of the sample in a waste container. 4.Eject the rest of the sample in a clean vial for storage. 5.Push the air you initially drew into the same vial. This step will push out the remaining fluid and will reduce the held up volume.
Sep 28, 2016 · Figure 4: Step by step syringe filtration – see text for details Basic method. This is the most basic method of using a syringe filter. Load the sample into the syringe. Attach the filter securely with a twisting motion. With a luer slip syringe, this is about one quarter turn as the filter is pushed on.
(without excessive force) the filled syringe to the filter device with a twisting motion. Apply gentle pressure to begin filtration. (A gentle pressure helps assure maximum throughput.) CAUTION: As the filter removes particulate, filtration will become more difficult (the syringe plunger will be harder to use) and pressure will rapidly increase on
Hydrophobic filters are best suited for gas filtration, low surface tension solvents, and venting. In certain applications, hydrophobic filters are used to filter aqueous solutions because of compatibility requirements. Water or aqueous solutions can also pass through a hydrophobic filter once the water breakthrough pressure is reached.
Membrane filtration. Use membrane filters having a nominal pore size not greater than 0.45 µm whose effectiveness to retain microorganisms has been established. Cellulose nitrate filters, for example, are used for aqueous, oily and weakly alcoholic solutions and cellulose acetate filters, for example, for strongly alcoholic solutions.
