Choice of membranes: • Durapore: PVDF membrane with very low protein binding. • Express: PES membrane combining low protein binding and rapid filtration. • Cellulose ester: standard membrane with a variety of uses, available in many porosities. • LCR: Hydrophilic PTFE, universal, for aqueous solutions and solvents.
Choice of membranes: • Durapore: PVDF membrane with very low protein binding • Nylon • Fluoropore: hydrophobic PTFE for gas and organic solvent filtration • LCR: Hydrophilic PTFE, universal, for aqueous solutions and solvents • Fibreglass
The non-sterile Millex filters have a 33 mm diameter and offer almost 20% more filtration surface than the 25 mm filters. This allows you to work with better flow rate and performance while maintaining a low dead volume (< 80 µl).
