Description

Designed for rapid clarification and sterilizing filtration of complex aqueous solutions, the FeaVacu Vacuum Filtration Device with Hydrophilic PES Membrane provides high-throughput liquid filtration for cell culture media, serum, buffers, and other laboratory solutions.

Featuring a 0.22 μm hydrophilic PES membrane, this vacuum filtration device effectively removes microorganisms and particles while helping preserve active ingredients by minimizing adsorption or decomposition. It is suitable for sterile filtration workflows where fast flow rate, reliable bacterial retention, and clean filtrate quality are required.

The device is made from polystyrene (PS) that meets USP Class VI standards and is available in 250 mL, 500 mL, and 1000 mL formats. The complete system consists of a vacuum bottle top with nozzle and a receiving bottle, offering a convenient single-use solution for laboratory, cell culture, and bioprocess filtration applications.
