Acro Disc Syringe Filters w/ PTFE Membrane - 0.45um, 4mm, 750/Pk SKU: 4472

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 4mm - 4472

Reducing background noise in analytical assays begins with proper clarification, and the Polytetrafluoroethylene (PTFE) Syringe Filters is engineered to remove interfering solids efficiently. Facilitating rapid sample turnover, the hydrophobic Polytetrafluoroethylene (PTFE) membrane structure ensures the 0.45 rating remains consistent even under pressure. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics
