Midisart®
Midisart® 2000 is a compact, disposable filter cartridge that pairs a hydrophobic PTFE membrane with a rugged housing to deliver sterile venting of air/gas and pressure- or vacuum-driven liquid filtration. Engineered for high flow rates, it streamlines laboratory sterilization, microbiology workflows, and general aseptic handling.
Its plug-and-play design ensures ease of use and dependable performance that meets USP requirements. Two pore-size grades—0.2 µm for sterilizing-grade protection and 0.45 µm for clarification—let you match the filter precisely to your process.
