I have to add this clean the media bottles, beakers, and graduated cylinders then sterilized them there is way to do this with 70% iso, cover beakers and cylinders with aluminum foil, put in over.
Then you can use a little bit of ethanol to make sure they are extra sterile.
Korsaire is on point!
do your self a favor and invest in an autoclave. it will take all the guess work out of it and you can sterilize everything in about 45min. works for me and quarantees your stuff will be clean and safe
