4/27/2022 0 Comments Choosing a Syringe FilterWhen you're looking to purchase a syringe filter, you'll want to choose one that meets your specific requirements. When selecting a syringe filter, see page on the several factors to consider, including membrane diameter, pore size, and housing type. The diameter of the filter is important because it determines the total volume filtered. Some filters are more flexible than others, so you may have to adjust the diameter to suit your needs. A syringe filter's pore size is important because particles can clog up the filter and reduce the amount of usable space. If particles are allowed to accumulate on the filter, it will plug more quickly and limit the useable volume. Therefore, you may want to choose a syringe filter that is larger in size to accommodate dirtier samples. However, keep in mind that if you are not careful, you may damage the filter by pushing it too hard. When choosing a syringe filter, consider what type of filtration it will perform. For aqueous samples, choose a syringe with a hydrophilic membrane, such as Nylon, PES, or GHP. Different materials and applications require different syringe filters, so make sure you know what type you need before purchasing a product. You may want to consider sterilizing your syringe filter if you plan on using it with any type of solvent. Generally, the syringe filter that works best for you will be able to eliminate microorganisms. The choice of materials can depend on your specific needs, and if you need a more robust filter, choose polyethersulfone. Polyethersulfone, however, can be problematic when it comes to removing proteins, so you should choose a filter that is compatible with the solvent you're using. If you're looking for a filter that will effectively remove particulates from your sample, then the Whatman Mini-Uniflo syringe filter on: chromtech.com, may be the right choice for your application. The 0.4-mL chamber contains a filtration membrane, which removes solids from liquid samples. The cap/septum on the syringe filter is designed to resist organic solvents. This feature makes it the ideal choice for clarification of organic solvents. A syringe filter is a single-use membrane based filter cartridge used in laboratory procedures. Most are equipped with Luer lock fittings and a needle attachment. They typically have a plastic housing with a membrane. By forcing the fluid through the filter, particles and debris are removed from the sample. It also works well for smaller volumes, making it an ideal solution for any lab. It is also inexpensive, making it a suitable choice for general purpose filtration. Once you have sterile syringe filters, it is time to attach them to the syringe. When you have attached the filter, turn the syringe in a clockwise motion. Be sure to do not overtighten it, as this can cause the filter housing to rupture. Then, push the plunger through the filter carefully and then purged the filter. This helps in maximizing sample throughput. Find out more here: https://en.wikipedia.org/wiki/Syringe.
