Pura Disc 25mm PES Syringe Filters, 1.0um, 200 Pk SKU: 6781-2510

Polyethersulfone (PES) Syringe Filters, 1.0µm, 25mm - 6781-2510

Designed to protect sensitive chromatography columns from clogging, the Polyethersulfone (PES) Whatman Puradisc, 25mm, Syringe Filter, 1.0µm, nonsterile 200/pk delivers exceptional retention of particulates without compromising flow rates. Facilitating rapid sample turnover, the hydrophilic Polyethersulfone (PES) membrane structure ensures the 1.0 rating remains consistent even under pressure. 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.
