Acro Disc Syringe Filters w/ Versapor Membrane - 5um, 25mm Modified Acrylic Housing, 300/Pk SKU: 4489

Acrylic Copolymer Syringe Filters, 5µm, 25mm - 4489

Versapor® acrylic copolymer filters are specifically engineered to navigate the challenges of difficult-to-filter solutions where standard membranes often fail. Driving this versatility is a robust copolymer matrix that resists blocking when filtering viscous fluids that would typically foul standard filters. 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.
