Metricel Black PES Membrane Disc Filter - 0.8um, 47mm, Gridded, 100/Pk SKU: 66588

Polyethersulfone (PES) Membrane Filters - 66588

Precision-manufactured Hydrophilic membrane with a verified 0.8 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. A uniform Polyethersulfone (PES) matrix maintains its rated 0.8 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. As a result, from raw polymer through final inspection, the manufacturing process is designed to ensure that every membrane disc meets the performance specifications of its grade designation.

Material Specifications

• Rigorous quality controls validate retention at rated pore sizes, positioning PES for critical pharmaceutical and biotechnology filtration.
• Minimal background interference from extractables ensures PES membranes protect the integrity of sensitive biological preparations during filtration.
• Asymmetric membrane architecture concentrates the retentive layer at the surface while maintaining an open substructure for sustained high flow.
• Materials of construction maintain their mechanical and chemical properties at temperatures up to 55°C, supporting heated filtration protocols.
• Naturally hydrophilic, PES membranes require no pre-wetting and offer broad compatibility with aqueous buffers, alcohols, and mild organic solvents.

Transitioning from qualitative screening to quantitative gravimetric analysis requires a membrane with documented tare weight consistency, and the manufacturing tolerances above ensure that your blank values remain within acceptable limits. To support this, 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. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

Hydrophilic

• Microarray Substrate - Provides a low-background surface for protein array printing, minimizing noise in high-throughput screening applications.
• Large Volume Processing - Filters liters of culture media in vacuum filter units, offering the fastest flow rates for routine lab preparations.
• TFF Cassette Production - Used as the core membrane in flat-sheet tangential flow filtration devices for protein concentration and diafiltration.
• Enzyme Recovery - Ensures minimal yield loss during the filtration of dilute enzyme solutions due to its inherently low-binding surface.
• Bioreactor Sampling - Integrated into sampling ports to allow fluid withdrawal from bioreactors without compromising the vessel environment.
• Tissue Culture Support - Acts as a porous growth support for 3D tissue culture inserts, allowing nutrient diffusion while anchoring the cells.
