Pall
Acro Disc Syringe Filters w/ wwPTFE Membrane - 0.2um, 25mm, 1000/Pk SKU: 4929

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.2µm, 25mm - 4929

Designed to eliminate the risk of selecting the wrong filter, the wwPTFE membrane offers broad chemical compatibility without the need for pre-wetting. Driving this analytical precision is an HPLC-certified membrane that ensures low UV-absorbing extractables for noise-free baselines. 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.
