PTFE Hydrophilic Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Sterile, 100 /Pk SKU: SF18250

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18250

Featuring advanced hydrophilic PTFE membrane technology at 0.45μm pore size, combined with ready-to-use sterile packaging, engineered for medium-volume clarification applications where contamination control is essential but bacterial removal is not required. Surface-modified fluoropolymer chemistry eliminates pre-wetting requirements while delivering exceptional 35ml flow rates for rapid sample preparation. Pharmaceutical quality control, clinical diagnostic testing, and research laboratories demand clarification solutions that provide immediate-use capability through sterile packaging eliminating handling contamination risks. Construction specifications include 25mm diameter platform with 4.08cm² filtration area, polypropylene prefilter integration extending membrane operational life, and 100μL holdup volume optimization supporting 50ml throughput capacity for demanding medium-volume clarification workflows requiring both processing speed and contamination-free handling.
