Metricel Black Membrane, 0.8um, 47mm, Grid, Gamma-Irradiated , Bulk w/ Parchment Separators, 200/Pk SKU: 66587

Polyethersulfone (PES) Membrane Filters - 66587

Designed to deliver reproducibility and confidence across critical sample types, the Pall 66587 provides the filtration consistency that method validation demands. Verified 0.8 pore distribution across the Hydrophilic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. In sum, controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• Temperature rating of 55°C provides the thermal headroom required for warm sample processing, heated media preparation, and elevated-temperature analytical methods.
• Asymmetric membrane architecture concentrates the retentive layer at the surface while maintaining an open substructure for sustained high flow.
• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.
• Minimal background interference from extractables ensures PES membranes protect the integrity of sensitive biological preparations during 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. To that end, the low extractable profile of PES membranes ensures that your filtrate remains free of membrane-derived contaminants, protecting the baseline stability your chromatographic and spectroscopic analyses require. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

• Tissue Culture Support - Acts as a porous growth support for 3D tissue culture inserts, allowing nutrient diffusion while anchoring the cells.
• Enzyme Recovery - Ensures minimal yield loss during the filtration of dilute enzyme solutions due to its inherently low-binding surface.
• 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.
• Bioreactor Sampling - Integrated into sampling ports to allow fluid withdrawal from bioreactors without compromising the vessel environment.
• TFF Cassette Production - Used as the core membrane in flat-sheet tangential flow filtration devices for protein concentration and diafiltration.
