A PL Specimen Jar (Plastic Specimen Jar) is a transparent plastic container used in laboratories and medical facilities for collecting, storing, and preserving biological specimens such as tissues, insects, plants, or liquid samples. The jar is made from high-quality clear plastic material and comes with a tight-fitting screw cap or lid to prevent leakage and contamination. Its transparent body allows easy observation of the specimen without opening the container. PL specimen jars are widely used in biology laboratories, medical labs, schools, colleges, and research institutions for demonstration, storage, and transportation of specimens.
