0.2 & 0.45 µm membrane filters are widely used in Legionella testing and environmental water microbiology laboratories. These membrane filters are commonly used during ISO 11731 membrane filtration procedures to concentrate bacteria from water samples prior to culture-based analysis.

Laboratories frequently use sterile gridded membrane filters together with vacuum filtration systems and 250 mL filter funnels for microbiological testing workflows.

0.2 & 0.45 µm membrane filters are commonly used for:

• Legionella testing
• Potable water analysis
• Environmental water microbiology
• Cooling tower monitoring
• Pharmaceutical water systems
• Industrial water testing

Membrane filtration improves bacterial recovery by concentrating microorganisms onto the membrane surface before transfer onto selective agar media.
