MCE Membrane Filters, White w/Black Grid, 0.8um, 47mm, Sterile, w/Pds, 100/Pk SKU: SF18162

Mixed Cellulose Ester (MCE) Membrane Filters - SF18162

The Tisch SF18162 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Reproducible separation characteristics define the membrane structure, protecting downstream instruments and preserving sample integrity throughout the filtration process. In sum, precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Known for excellent wetting properties and high flow rates in aqueous filtration.
• Hydrophilic by nature, the MCE membrane structure supports high non-specific adsorption for effective organism capture.
• Built-in hydrophilic character allows direct processing of buffers, culture media, and aqueous reagents without membrane conditioning steps.
• Mixed Cellulose Ester membranes combine cellulose acetate and cellulose nitrate polymers to deliver a smoother, more flexible membrane surface than pure cellulose nitrate.
• Feature a uniform pore structure that provides consistent flow rates and high throughputs across the full range of standard pore size ratings.

Maintaining accreditation under ISO 17025 or similar quality frameworks requires documented traceability at every step — the specification compliance of each membrane lot supports your ongoing audit readiness. To meet this need, naturally hydrophilic MCE wets immediately on contact with aqueous samples, eliminating pre-conditioning and letting you begin filtration as soon as the membrane is seated. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• Chemotaxis Assays - Acts as a barrier in Boyden chambers, allowing cells to migrate through defined pores towards a chemoattractant source.
• Biochemical Assays - High electrostatic properties effectively bind proteins and macromolecules, supporting various diagnostic and research assays.
• Microscopy mounting - Can be made transparent with immersion oil, allowing for direct light microscopy of retained particles on the surface.
• Aqueous Filtration - Biologically inert composition provides high flow rates and consistent reliability for routine laboratory fluid processing.
• Bioburden Monitoring - Routine testing of pharmaceutical water loops to ensure bioburden levels remain within safe production specifications.
• Yeast & Mold Monitoring - Optimized for the recovery of larger fungal organisms in beverage testing, providing a clear background for ID.
