2. Prerinsing
Membranes fitted to Spin-X
UF concentrators contain trace amounts of glycerin and
®
sodium azide. Should these interfere with analysis they can be removed by rinsing fill
volume of buffer solution or deionized water through the concentrator. Decant filtrate
and concentrate before processing sample solution. If you do not want to use the pre-
rinsed device immediately, store it in the refrigerator with buffer or water covering
the membrane surface. Please do not allow the membrane to dry out.
3 . Sterilization of Polyethersulfone Membranes
Polyethersulfone membranes should not be autoclaved as high temperatures will
substantially increase membrane MWCO. To sterilize, use a 70% ethanol solution
or sterilizing gas mixture.
