Hydrophilic PTFE Membrane Filters, 0.22 um, 250mm, Nonsterile, 25/Pk SKU: SF18461

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22µm, 250mm - SF18461

When sample purity is non-negotiable, the Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22um, 250mm, Nonsterile, 25/pk serves as a reliable safeguard, effectively removing microorganisms from aqueous solutions. Driving this efficiency is the integration of a hydrophobic Polytetrafluoroethylene (PTFE) membrane, ensuring high recovery of sensitive samples while maintaining a sterile effluent. Manufactured with strict thickness tolerances, these membranes provide a reliable barrier for critical filtration steps without compromising flow. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics
