Mixed Cellulose Ester (MCE) Membrane Filters - SF17477

The Tisch SF17477 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. In turn, consistent surface properties across the full membrane area support uniform particle capture and reliable results in gravimetric, microscopic, and culture-based analytical workflows.

Material Specifications

• Known for excellent wetting properties and high flow rates in aqueous filtration.
• Mixed Cellulose Ester membranes combine cellulose acetate and cellulose nitrate polymers to deliver a smoother, more flexible membrane surface than pure cellulose nitrate.
• 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.
• The biologically inert blend of cellulose acetate and cellulose nitrate provides a membrane surface optimized for organism capture and colony enumeration in microbiological assays.
• Feature a uniform pore structure that provides consistent flow rates and high throughputs across the full range of standard pore size ratings.

Microbial enumeration methods require complete retention at rated pore size and a growth-supporting surface. The membrane specifications above confirm both requirements for your culture-based workflows. In response, the uniform surface structure of mixed cellulose ester membranes provides the optically flat background that your microscopy and particulate analysis methods require for accurate visualization and particle counting. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
