What do you do when packaging specimens

When packaging specimens, the bacteria or specimen should be put in a petri dish or container. When closed tightly, they should be put in two bags that can be sealed properly and put away. To keep the specimen fresh and usable, it should be kept in a place that is cool and not humid. In addition, it is best to do this while wearing goggles, gloves and a lab coat. Remember to wash your hands before and after the procedure; also, record all observations, throw away waste and put away all equipment when all experiments are done.
