Wash your glassware (as you always should)
but pay careful attention to keeping everything DRY
. After doing a soap wash, rinse your glassware
with acetone (found in the metal canisters in each sink). Air
dry the glassware either with paper towels or the air from the
lab air valve (orange valve marked "LA" located on the
hoods at the perimeters of the room).
Please dispose of all acetone waste in the proper waste bottles
located in the hoods.
Why is it important to keep your glassware dry in this particular
experiment?
