I am planning to concentrate phages in wastewater with Amicon Ultra-15.

I will concentrate 40 mL of the sample by repeating centrifuging for four times (10 mL each time)

I have learned that the membrane shouldn't get dried, but i don't understand why. Could anyone tell me the reason?

Also how much should I keep it wet? Should I always keep the membrane soaked in water? Or, can't it contact the air at all?
