Thermo Scientific™ Choice™ PVDF (hydrophillic) Syringe Filters are a good option for general biological filtration. They are especially well-suited for applications where high protein recovery is desired. Choice PVDF (hydrophillic) Syringe Filters do not require pre-wetting with an alcohol for aqueous samples.
Syringe filters provide cleaner sample extracts by removing interfering materials and fine particles down to the rated pore size. Adding a syringe filtration step prior to chromatographic injection helps to ensure more consistent and reliable results, and helps to protect instruments and prolong column life. Economic Choice Syringe Filters are available in a variety of sizes and membrane types to meet any application need.
