Thermo Scientific syringe filters remove interfering materials, fine particles, and microorganisms, providing you with cleaner sample extracts. Using syringe filters prevents the accumulation of fine particles that can block your chromatography column.
These high-quality robust sample filtration solutions are available in a variety of syringe filter sizes, membranes, and housings for a wide range of samples and applications. Choose from three different brands: Titan3 for premium filters, Target2 for routine use, or economy brand Choice. Use in combination with Thermo Scientific disposable syringes.
