excuse me, what method should be used to sterilize the rubber tube and plexiglass? How long? -it can be sterilized by damp heat, which is the general kind of sterilization pot. Commonly used are 115 or 121 degrees for 3 minutes -1 hour.

can the rubber hose be soaked in 7% alcohol? -It has been answered above, so it is unnecessary. I don't know for a long time. I think it may be broken. It's okay to soak for a short time.

Organic glassware can't use alcohol, it will crack. Should we use ultraviolet? -Yes, no alcohol! Use ultraviolet light.

how to operate the osmotic water absorption method? Is the sterilization effect good? -I have never heard of it, and I have never used it. I am ashamed. I'm a microbiologist. I usually sterilize. I only use a sterilizer or ultraviolet light ...

I hope it helps you.
