Product Benefits

Sterile Individual Packaging

Each membrane is individually sealed in an S-Pak® package, reducing the risk of contamination and eliminating the need for additional sterilization before use.

Excellent Bacterial Retention

The 0.45 μm pore size efficiently captures bacteria and suspended microorganisms while maintaining excellent flow rates.

Printed Grid for Easy Colony Counting

The precision-printed grid provides clear reference points, making microbial colony counting faster, easier, and more accurate.

Hydrophilic Membrane

Designed for aqueous solutions, the membrane wets instantly without alcohol pre-wetting, simplifying laboratory procedures.

High Flow Performance

The highly porous MCE membrane allows rapid filtration with minimal sample loss, improving laboratory efficiency.

Bright White Surface

The white membrane offers excellent visual contrast, making bacterial colonies highly visible during microbiological analysis.
