If I were Dr. Seuss, I will describe our occupation like this:
We are experimental chemists
We do synthesis
We measure the properties of the products
And we clean up the flask in the final acts
Yes, cleaning up the flask is a vital part of your experiment. We use base bath every day. But, because it is an everyday thing, and all members of the research group use it, there are some issues you need to know.
(i) How to make base bath
First, take extra precautions. Wear thick black gloves, rubber apron, eye protection, and a face shield. Mix approximately 200–300g of solid KOH, 4 L of isopropyl alcohol, and 1L of deionized water.
(ii) How often would you replace once a semester
When you see dirt in the base bath, you need to replace the bath. Otherwise, renew the base bath once per semester.
(iii) Put the clean glassware in the base bath
Basebath is the place where clean glassware becomes super clean. Rinse the glassware thoroughly both inside and outside and brush if necessary. If you put a flask that you used for a reaction that is new to you, you should return to the base bath to make sure that it was enough. Sometimes, transparent chemicals were stuck inside and reduced. In that case, take the glassware out and clean it using brushing, sonication, or acid solution, and put it back into the base bath.
(iv) Teamwork
Basebath is a symbol of cooperation. Even if you did not do any experiments for a week, if it is your turn, you should clean the glassware.
(v) Log note
A sign-up form is an excellent way to remind people of glass-cleaning duty.
My Google search revealed a lot of procedures like this. You should do your own Google search, too.
