Acro Disc Syringe Filters w/ Supor Membrane, Sterile - 0.45um, 13mm, 75/Pk SKU: 4604

Polyethersulfone (PES) Syringe Filters, 0.45µm, 13mm - 4604

Optimized for biological performance, the Supor® Syringe Filters combines high flow rates with the assurance of low preservative binding. Driving this biological efficiency is an ultra-low protein binding surface that minimizes the loss of active ingredients during sterile filtration. To guarantee structural reliability, each unit undergoes strict quality control to ensure the housing and membrane seal withstand standard operating pressures without leakage. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.
