5 Wetting the filtration membrane
NOTE
In the package containing the filtration membranes, you will find
sheets of different thicknesses and colors:
￭ The firm white cardboard is a cover protecting the filtration
membranes. Do not place it in the ultrafiltration cell.
￭ The thin light-blue sheets are separation sheets placed between
two filtration membranes. Do not place them in the ultrafiltra-
tion cell.
￭ The thin white sheets are the filtration membranes. Use only
these for ultrafiltration.
￭ Using the tweezers, take a new filtration membrane out of the
package.
￭ Place the filtration membrane in a petri dish filled with ultrapure
water and allow to hydrate for approx. two minutes.
6 Inserting the filtration membrane
NOTE
Make sure that the water-soaked filtration 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.
￭ Using the tweezers, place the wet filtration membrane centrally
inside the sealing ring onto the cell.
