APPENDIX 2: MEMBRANE CUTTING AND CONDITIONING
Sterlitech oers a wide variety of membranes that have been pre-cut for use with the
HP4750. However, if you need cut your own membrane for use with the HP4750 Stirred
Cell, then you will need the following items:
• The porous stainless steel support disk, which will serve as the template
• The membrane sheet to be cut
• A pair of sharp scissors
• A pair of latex gloves
To cut a membrane disk filter for the HP4750:
1. Take the porous stainless support disk and
place the membrane sheet against it. Be
sure to have the latex gloves on to avoid
contaminating the membrane surface.
2. Cut along the edge of the template with
the scissors. Hold the scissors at an angle
towards the center of the template to
avoid undertrimming (Photo 17). Once
finished, the membrane should sit perfectly
flat on supports without any bending and
extend outside of the inner O-ring to avoid
leakage (Photo 18).
