1, Select the aperture size according to the application requirements.

  • 0.45μm ； Buffer clarification/pre-filtration.
  • 0.22μm ； Clarification of media and actual aseptic filtration.

2，Depending on the type of liquid, the appropriate membrane is selected to optimize the flow rate.

  • PES ; Highly recommended for use in cell media, serum, and buffer solutions. Very low protein binding, fast flow rate, very low extraction, not resistant to organic solvents and strong acid and base solutions; PH:1-13.
  • CA ; Limited chemical compatibility, low protein binding; Used in buffer salt solution, protein recovery experiment.

3，Capacity is selected according to the filtration volume to maximize liquid flux while minimizing retention volume.

  • Filter up ; 250m , 500mlM
  • atching receiving bottle ; 250ml , 500ml

The disposable vacuum filter cup is a self-contained filtration system that combines a filter funnel, receiving bottle and interface.
