16. Not properly storing the reagents
This is another major mistake that is made by researchers. Improper storage of reagents may result in damage of the reagents and ultimately experiment fails.
17. Eating inside the lab
Yes, it is a major mistake people do. We should not eat inside a lab be it a chemical lab or a biology lab. And when it is a microbiology lab then it is a complete no. We might end up either contaminating the food or the room.

Many researchers are there who use the microwave for heating food, refrigerators for storing food and sometimes the distilled water for making coffee. It should not be done, seriously.
