Porex TruFlowTM Absorbent Pads

Optimized for Consistency and Manufacturing Ease

Porex TruFlowTM absorbent pads have a consistent wicking volume and rate to minimize backflow of excess reagents

The absorbent pad absorbs all of the volume of the assay. Also known as a wick pad, Porex TruFlowTM absorbent pads have high absorption capacities while maintaining the tensile strength needed for reel to reel manufacturing. Porex TruFlow lateral flow assay pads do not include any glass fiber or cellulose, which ensures increased strength and durability for manufacturing. Our synthetic polyolefin-based fiber is uniform and hydrophilic for consistent absorption.
