Acro Disc Syringe Filters w/ Supor Membrane - 5um, 32mm Modified Acrylic Housing, 1000/Pk SKU: 4662

Polyethersulfone (PES) Syringe Filters, 5µm, 32mm - 4662

Engineered for speed and recovery, the Supor® Syringe Filters processes buffers and tissue culture media significantly faster than standard PES devices. Central to this high-throughput capability is the Supor® PES membrane, optimized with an asymmetric pore structure to deliver superior flow rates. 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.
