MCE Circle ME Range (ME 25), Plain, 0.45um Pore Size, 110mm, 50pk SKU: 10401626

Mixed Cellulose Ester (MCE) Membrane Filters - 10401626

The 10401626 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. Quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. Each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Feature a uniform pore structure that provides consistent flow rates and high throughputs across the full range of standard pore size ratings.
• Hydrophilic by nature, the MCE membrane structure supports high non-specific adsorption for effective organism capture.
• Rated for continuous operation at temperatures reaching 130°C, enabling filtration of heated solvents and process fluids without material compromise.
• Low tare weight and complete solubility in organic solvents make MCE the standard membrane for gravimetric particulate analysis where method specifications demand minimal blank correction.
• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.

Scaling your method from development to routine production requires membrane consistency at every lot — the documented specifications of these membranes provide the reproducibility needed to validate the filtration step once. MCE's well-documented retention characteristics at standard pore ratings make it straightforward to specify in your method documentation, supporting the reproducibility and traceability that regulated workflows demand. Sample quantities for method validation and compatibility testing are available through Tisch Scientific — request a sample to verify performance in your specific workflow before committing to a production volume.

Hydrophilic

• Gravimetric Analysis - Captures total suspended solids from liquid samples on a weighed disc, ensuring accurate mass measurements for reporting.
• Stack Pre-filtration - Acts as a spacer or depth layer in multi-tier filtration stacks to extend the life of the final downstream membrane.
• Sediment Collection - Efficiently harvests precipitates from chemical reactions, allowing for the recovery and drying of the solid synthesis product.
• Radiometric Counting - Collects radioactive precipitates for scintillation counting, providing a consistent geometry for accurate data measurement.
• Microscopy mounting - Retains microorganisms on a flat surface, allowing for direct staining and enumeration under a high-power microscope.
• Vacuum Clarification - Utilized in Buchner funnels to rapidly remove particulates from large-volume batches of non-critical laboratory buffers.
