Pura Disc 13mm PVDF Syringe Filters, 0.45um, 500 Pk SKU: 6792-1304

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.45µm, 13mm - 6792-1304

In high-throughput analytical laboratories, the Polyvinylidene Difluoride (PVDF) Whatman Puradisc, 13mm, Polyvinylidene Difluoride Syringe Filter, 0.45µm 500/pk series establishes a standard for effective particulate removal and sample clarification. Facilitating rapid sample turnover, the hydrophobic Polyvinylidene Difluoride (PVDF) membrane structure ensures the 0.45 rating remains consistent even under pressure. 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.
