Acro Disc Syringe Filters w/ Supor Membrane - 0.45um, 32mm Modified Acrylic Housing, 1000/Pk SKU: 4653

Polyethersulfone (PES) Syringe Filters, 0.45µm, 32mm - 4653

When maximizing protein recovery is critical, the Supor® Syringe Filters delivers an ultra-low binding surface that protects your valuable active ingredients. At the core of the device is the specialized polyethersulfone matrix, which resists clogging to filter greater volumes of biological fluids. To guarantee structural reliability, each unit undergoes strict quality control to ensure the housing and membrane seal withstand standard operating pressures without leakage. 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
• Verified 0.45 retention rating for clarification

Key Housing Characteristics

• High-purity Polypropylene encapsulation housing
• Luer-Lock/ Luer Slip for secure fitting
• 5.8cm² effective filtration area
• < 100 µl holdup volume to minimize sample loss

When you integrate these filters into your daily standard operating procedures, you are choosing a workflow that prioritizes efficiency without compromising results. You invest significant resources into your samples; safeguarding them with a proven filtration barrier is a cost-effective insurance policy for your lab. When performance cannot be compromised, rely on the brand that has defined the science of filtration for decades.
