For example, if we are using acetonitrile and water (84:16) mixture for the extraction of aflatoxin. So, whether this mixture (acetonitrile and water) is prepared fresh or not? and why?
Preferable evaporation of acetonitrile in storage will results in leass than 84% as per the original solution. Best to prepare fresh each time
Many answered correctly ?

I had a crystal hit in a well with 0.1M HEPEs pH 7.5, 10%(w/v) PEG 4000, and 20%(w/v) isopropanol. Why is isopropanol in w/v here if it's just solvent? How do I recreate this well condition?
