Volumetric flask washing method
[volumetric flask 100ml,lab flask amber volumetric,Volumetric Flask Capacity 2000 Ml ]
The small volumetric flask can be filled with lotion and soaked for a certain period of time.
A large volumetric flask does not need to be filled. Fill in about 1/3 of the volume of lotion, stopper the bottle tightly, shake it for a while, and then shake it several times at intervals to wash it off.
After the volumetric flask is used, it should be washed clean in time, stoppered, and a strip of paper should be inserted between the stopper and the mouth of the bottle to prevent the stopper from sticking to the mouth of the bottle. Or, keep the volumetric flask as dry as possible, pour a little lotion into the volumetric flask, turn the volumetric flask so that the inner wall is soaked with the lotion, and then pour the lotion back into the original bottle for reuse. Rinse the remaining lotion in the bottle with two waters until it is clean, and finally rinse with distilled water.
