What Is a Sterile Filter Cartridge? Why Choose Entegris Sterile Filters? | Filterfine Vietnam

1. What Is a Sterile Filter Cartridge?

A sterile filter cartridge is an essential component in liquid filtration systems, designed to remove bacteria, yeast, and other microorganisms from liquids. Sterile filters typically use microfiltration or ultrafiltration membranes with pore sizes ≤ 0.22 µm, providing reliable bacterial retention without altering the chemical composition or therapeutic properties of the filtered solution.

Key Benefits of Sterile Filter Cartridges

• Prevent microbiological contamination (bioburden) in pharmaceutical liquids
• Protect fermentation, cell culture, and vaccine production processes
• Ensure sterility requirements during final filling, storage, and downstream processing
• Minimize microbial clogging and maintain consistent product quality
