VWR Bottle Top Filter Unit 1 L 0.2 um Indiv Sealed PES 12 Filter Units

The VWR 97066-204 Bottle Top Filter Unit is a single-use filtration device designed for the rapid and sterile clarification of liquids. This unit is composed of a funnel that screws directly onto a standard laboratory bottle, creating an integrated system for vacuum filtration. It has a 1-liter capacity and features a 0.2 µm PES (polyethersulfone) membrane, which is the industry standard for sterile filtration, as it effectively removes bacteria and other microorganisms from liquids.

PES membranes are known for their high flow rates and low protein binding, making this filter unit ideal for preparing cell culture media, buffers, and other biological fluids where preserving the integrity of the solution is critical. The single-use design eliminates the need for cleaning and sterilization, which saves time and reduces the risk of cross-contamination, contributing to a more efficient and reliable workflow in cell biology, microbiology, and other life science laboratories.
