Acro Disc PF Syringe Filters w/ Supor Membrane, Sterile - 0.8/0.2um, 25mm, 50/Pk SKU: 4187

Polyethersulfone (PES) Syringe Filters, 0.8µm, 25mm - 4187

Supor® polyethersulfone (PES) membranes represent the industry gold standard for high-throughput sterile filtration of biological fluids. 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. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.

Key Polyethersulfone (PES) Membrane Characteristics
