Acro Disc Syringe Filters w/ Supor Membrane, Sterile - 0.2um, 25mm, 50/Pk SKU: 4612

Polyethersulfone (PES) Syringe Filters, 0.2µm, 25mm - 4612

When maximizing protein recovery is critical, the Supor® Syringe Filters delivers an ultra-low binding surface that protects your valuable active ingredients. Central to this high-throughput capability is the Supor® PES membrane, optimized with an asymmetric pore structure to deliver superior flow rates. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.

Key Polyethersulfone (PES) Membrane Characteristics

• Polyethersulfone (PES) membrane with hydrophilic affinity
• Ultra-Low Protein Binding characteristics
• Broad compatibility (pH 1-14), ideal for biologicals
• Not compatible with aggressive ketones or esters
• 0.2 rating suitable for sterile filtration

Key Housing Characteristics

• High-purity Polypropylene encapsulation housing
• Luer-Lock/ Luer Slip for secure fitting
• 2.8cm² effective filtration area
• < 300 µl holdup volume to minimize sample loss

By selecting a filter that matches the exact chemical nature of your samples, you ensure that your workflow remains uninterrupted by membrane failures. Trust in the consistent performance of your filtration step to remove the variables that often lead to costly re-runs and ambiguous data. When performance cannot be compromised, rely on the brand that has defined the science of filtration for decades.
