Membrane filter

for liquidslaboratoryfor pump

Product introduction
Microporous membrane filters are a primary solution in membrane separation technology. Their simple handling and rapid filtration make them suitable for laboratories and industrial prefiltration. The disc-shaped membrane structure provides a consistent physical barrier to trap particles and microorganisms on the membrane surface.

Features

• Uniform pore diameter and high porosity for consistent particle retention
• Low resistance and high flux — filtration speed increased by more than 30% in typical conditions
• Available in multiple materials and pore sizes to match application requirements
• Consistent performance within and between production batches
• 0.22 μm membranes pass ≥1×10^7 CFU/cm² B. diminuta challenge retention test
