Sentino Metricel Black Membrane, 0.8um, Dispenser Packs of 200, 1000/Pk SKU: 68125

Polyethersulfone (PES) Membrane Filters - 68125

The Pall 68125 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. 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

• Naturally hydrophilic, PES membranes require no pre-wetting and offer broad compatibility with aqueous buffers, alcohols, and mild organic solvents.
• Engineered for rapid throughput, PES provides an asymmetric pore structure that resists premature clogging during high-volume filtration runs.
• Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.
• Rigorous quality controls validate retention at rated pore sizes, positioning PES for critical pharmaceutical and biotechnology filtration.
• Polyethersulfone (PES) membranes deliver high flow rates with ultra-low protein binding, making them the preferred choice for biological sample filtration.

Environmental monitoring programs where sample-to-sample comparability determines trend validity benefit directly from the lot-level consistency of these membranes, removing the filter as a variable in your long-term data sets. Because PES resists fouling from protein-rich samples more effectively than cellulose-based alternatives, you can process larger volumes through a single filter before flow degradation forces a mid-batch device change. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

• Bioreactor Sampling - Integrated into sampling ports to allow fluid withdrawal from bioreactors without compromising the vessel environment.
• Microarray Substrate - Provides a low-background surface for protein array printing, minimizing noise in high-throughput screening applications.
• Buffer Batching - Clarifies large batches of biological buffers in production, protecting downstream chromatography columns from fouling.
• Tissue Culture Support - Acts as a porous growth support for 3D tissue culture inserts, allowing nutrient diffusion while anchoring the cells.
• Large Volume Processing - Filters liters of culture media in vacuum filter units, offering the fastest flow rates for routine lab preparations.
• Enzyme Recovery - Ensures minimal yield loss during the filtration of dilute enzyme solutions due to its inherently low-binding surface.
