PTFE Hydrophilic Syringe Filters, 0.22 um, 30mm, Luer-Lok/Luer Slip, Sterile, 100 /Pk SKU: SF18263

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18263

Advanced 0.22µm hydrophilic PTFE membrane technology delivers absolute bacterial retention, supported by a validated 43.51psi bubble point for complete sterile filtration. The expanded 30mm diameter platform offers a large 4.9cm² filtration area, optimizing processing for volumes up to 110ml with accelerated 29.5 ml/min flow rates. Designed for critical pharmaceutical manufacturing and biotechnology scale-up, this system enables immediate sterile processing without pre-wetting delays or contamination risks. Quality assurance protocols validate membrane integrity, while the 100µL holdup volume efficiently balances sample conservation with the high throughput required for large-batch sterile operations.

Key PTFE Membrane Characteristics
