A word of caution here: some disposable cuvettes will simply dissolve in 
95% ethanol. So may be a 20% or so EtOH should be used if storage of 
cuvettes is intended. We had a dry sterilization chamber in one of our 
Prof.'s lab that used peroxide cans (?). The plastic stuff could be 
sealed in special pourous bags, sterilized that way and stored for future
