Answer:
the possibility of contamination in the laboratory is minimized
Step-by-step explanation:
When a particular laboratory equipment is used for a given purpose, it can not be used four another purpose until it has been thoroughly washed. This is done in order to avoid contamination when the equipment is subsequently used for a different purpose.
Hence, if a laboratory equipment is not properly cleaned and stored after use, they remain contaminated and give inaccurate results when subsequently used.
