5 Wetting the dialysis membrane
NOTE
In the package containing the dialysis membranes, you will find
sheets of different thicknesses and colors:
￭ The firm white cardboard is a cover protecting the filtration
membranes. Don not place it in the dialysis cell.
￭ The thin light-blue sheets are separation sheets placed between
two filtration membranes. Do not place them in the dialysis
cell.
￭ The thin white sheets are the dialysis membranes. Use only
these for dialysis.
￭ Using the tweezers, take a new dialysis membrane out of the
package.
￭ Place the dialysis membrane in a petri dish filled with ultrapure
water and allow to hydrate for approx. two minutes.
6 Inserting the dialysis membrane
NOTE
Make sure that the water-soaked dialysis membrane does not dry
out before it is inserted, as it can otherwise no longer be used.
￭ Place the sealing ring back in the recess.
