Pall
Acro Disc One Syringe Filters w/ wwPTFE Membrane - GxF/0.45um, 25mm, 200/Pk SKU: AP-4919

Hydrophilic PTFE (wwPTFE) Syringe Filters, 0.45µm, 25mm - AP-4919

The Acrodisc® One with wwPTFE (Water-Wettable PTFE) membrane dissolves the traditional distinction between aqueous and organic filtration workflows. To dissolve the barrier between aqueous and organic workflows, the hydrophilic PTFE structure wets immediately without the need for alcohol flushing. To guarantee structural reliability, each unit undergoes strict quality control to ensure the housing and membrane seal withstand standard operating pressures without leakage. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.

Key Hydrophilic PTFE (wwPTFE) Membrane Characteristics
