Choice™ PTFE (Hydrophobic) Syringe Filters

Use Thermo Scientific™ 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 materials and fine particles down to the rated pore size.

Adding a syringe filtration step prior to chromatographic injection not only helps to ensure more consistent and reliable results, it also 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.
