Refrigerators play a crucial role in science laboratories for several reasons. They provide a controlled environment with low temperatures for storing sensitive materials, such as biological samples, reagents, chemicals, and medications. Refrigeration helps preserve the stability and integrity of these substances, preventing degradation, denaturation, or spoilage. It is essential for maintaining the viability of living organisms, preventing enzymatic activity, and extending the shelf life of perishable items. Refrigerators in laboratories ensure the integrity and reliability of experiments, research, and medical applications.
