Pura Disc 13mm PES Syringe Filters, 0.2um, 100/Pk SKU: 6782-1302

Polyethersulfone (PES) Syringe Filters, 0.2µm, 13mm - 6782-1302

For critical applications requiring absolute sterility assurance, the Polyethersulfone (PES) Whatman Puradisc, 13mm, Syringe Filter, 0.2µm, nonsterile 100/pk series provides a verified barrier against bacterial contamination. Central to this performance is a hydrophilic Polyethersulfone (PES) membrane with a precise 0.2 pore structure that ensures the complete removal of bacteria and fine particulates. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.
