Use Thermo Scientific™ Choice™ syringe filters made of hydrophilic PTFE for filtration of aggressive organic, very basic or hot solutions and as transmitter protection. These Choice syringe filters can filter aqueous solutions without the need for prior wetting with alcohol. They provide cleaner sample extracts by removing interfering materials and fine particles up to nominal pore size. An additional filtration step prior to chromatographic injection not only ensures you get more consistent and reliable results, but also protects sensitive equipment and extends column life. Cost-effective Choice syringe filters are available in a variety of sizes and membrane types to meet all application requirements.
