Pall
Acro Disc Syringe Filters w/ Supor Membrane - 0.2um, 32mm Modified Acrylic Housing, 1000/Pk SKU: 4655

Polyethersulfone (PES) Syringe Filters, 0.2µm, 32mm - 4655

Engineered for speed and recovery, the Supor® Syringe Filters processes buffers and tissue culture media significantly faster than standard PES devices. At the core of the device is the specialized polyethersulfone matrix, which resists clogging to filter greater volumes of biological fluids. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.
