TPP Syringe Filters

TPP Syringe Filters are engineered by scientists for scientists, delivering superior performance in filtering small volumes of tissue culture media, aqueous solutions, buffers, additives, and water. Unlike standard syringe filters, TPP filters provide rapid throughput—3 to 5 times faster—thanks to their premium PES membrane and enlarged filter surface area. With low protein binding, high flow rates, and bi-directional functionality, these filters ensure reliable sterile filtration while preserving sample integrity.

Built with a robust 33 mm housing diameter, TPP Syringe Filters fit securely on 50 mL centrifuge tubes for ease of use in any laboratory workflow. Each unit is gamma-sterilized, DNAse/RNAse-free, and pyrogen-free, individually wrapped for sterility, and supplied in a convenient dispenser box. Ideal for sterile filtration of protein solutions, tissue culture media, additives, buffers, and water, TPP Syringe Filters combine speed, reliability, and ergonomic handling to optimize laboratory efficiency.
