Description
Specifications:
Hydrophilic PVDF membrane (Durapore®) — excellent for aqueous solutions and many solvents, with very low protein binding to maximize sample recovery.
0.22 µm pore size — effective removal of fine particulates and biological contaminants.
47 mm diameter — standard disc size for filtration holders and routines.
High flow rates: > 1 mL/min/cm² water and ~2 L/min/cm² air for efficient filtration throughput.
Low extractables (~0.5 %) — cleaner filtrates.
Broad chemical compatibility and solvent tolerance — suitable for many lab applications.
Non-sterile design for general laboratory use.
Applications:
Pre-filtration before HPLC/GC and other chromatography to remove particulates and protect analytical columns.
Clarification of buffers, reagents, and biological solutions.
Routine filtration of aqueous samples in chemical, environmental, and life science labs.
Preparation of samples for instrumental analysis (UV-Vis, MS).
