Sterilizing filters are essential components in industries requiring high-purity filtration, such as pharmaceuticals, biotechnology, and food processing. These filters remove microorganisms and particulates from liquids and gases, ensuring sterile conditions. Common types include membrane filters (e.g., PTFE, nylon) and depth filters, with pore sizes ranging from 0.1 to 0.45 microns. Key features: chemical resistance, high flow rates, and compatibility with autoclaving. Typical products: syringe filters, cartridge filters, and venting filters for bioreactors.
