Description

Use Thermo Scientific™ Choice™ Regenerated Cellulose (RC) Syringe Filters for low nonspecific binding applications as well as for tissue culture media filtration and general biological sample filtration. 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 helps to ensure more consistent and reliable results, protects delicate instruments, and prolongs column life. Economic Choice Syringe Filters are available in a variety of sizes and membrane types to meet any application need.
