Fisherbrand Filter Unit aPES 0.2 um Pore 75 mm Diameter 500 ml 6 Filter Units

Description

Fisherbrand Disposable Vacuum Filtration Unit – 500 mL, 0.20 micron Pore Size, 75 mm aPES Membrane, Sterile, Clear Polystyrene (MPN: FB12566504)

The Fisherbrand FB12566504 is a premium, complete laboratory vacuum filtration system precision-engineered for the high-velocity clarification, sterilization, and particle removal of tissue culture medias, biological buffers, sera, and biological fluids up to 500 mL. Molded from crystal-grade, clear polystyrene, this all-in-one assembly features an upper graduated filter funnel, a secure neck adapter matrix with a dedicated vacuum tube port, and a matching 500 mL storage receiver flask. Pre-packed with an asymmetric Polyethersulfone (aPES) membrane filter featuring a 75 mm nominal diameter and a 0.20 micron sterilization-grade cutoff pore size, this device provides exceptional flow rates and total throughput while maintaining an ultra-low protein-binding baseline.

Technical Performance and Design

• High-Flow Asymmetric PES Membrane: Equipped with an advanced hydrophilic asymmetric polyethersulfone (aPES) membrane. The specialized gradient pore structure acts as a built-in pre-filter layer, maximizing fluid flow rates and total volume capacity before membrane saturation.

• Ultra-Low Protein Binding Matrix: The natural surface chemistry of the aPES membrane material aggressively limits non-specific binding of critical proteins, active enzymes, growth factors, and amino acids, safeguarding the biochemical profile of downstream fluids.

• Ergonomic Dual-Graduated Profile: Both the upper funnel chamber and the lower collection receiver flask feature molded, high-contrast volumetric graduation markers, supporting effortless visual level verification and fluid monitoring throughout active filtration loops.

• Aseptic Gamma-Irradiated Baseline: Processed via validated gamma irradiation to achieve an industry-certified sterile and non-pyrogenic baseline. Every individual system arrives securely sealed within clean protective bags to maintain sterilization parameters.

Key Benefits and Applications

• Cell Culture Media Sterilization: The primary laboratory standard for filtration-sterilizing crude cell culture broths, stem cell expansion mixtures, growth additives, and fetal bovine serum (FBS) matrices.

• Aqueous Biological Buffer Clearing: Effectively removes ambient airborne particulate, trace salts, micro-aggregates, and bacterial bioburden out of chromatography-grade water and analytical liquid lines.

• Vacuum Flask Cross-Compatibility: The structural middle connection module hooks up cleanly to standard building vacuum tubes or benchtop laboratory aspiration pumps without the need for auxiliary inline adapters.

• Secure Eluate Storage Archiving: The lower 500 mL receiver vessel functions seamlessly as an archival container when paired with the included leak-resistant screw cap, allowing technicians to store sterile aliquots inside clean refrigeration vaults.
