All About Petri Dish & Uses

Post by Mike Kirsten

Petri dish is 1 of the most essential laboratory consumable products utilised in biological laboratories. Petri dish is made of either glass or transparent plastic. It is a shallow cylindrical dish primarily used to culture cells.

It was named soon after a German bacteriologist Julius Petri, who invented it during working as an assistant to Robert Koch. Petri dishes produced of glass can be used once more and once more by sterilization even though the plastic petri dishes once utilized can’t be utilized once more. They ought to be disposed of soon after one use.

Petri dishes are generally filled with a growth medium created of agar. Agar is a gelatinous substance created with extracts from red algae and a variety of nutrients. The nutrients added might vary according to the will need of the organism being cultured.

Uses of Petri Dishes

The primary use of petri dish in a laboratory is to culture cells. Petri dishes are utilised in schools and colleges to teach students about the seed germination. The transparent material of the petri dish helps students to observe each step of growth of seed. The size of petri dish is best to be placed under a microscope so it is also utilized for dissection. In laboratories, petri dishes can be used for fundamental experimental purposes such as transferring liquids in sterile containers for study.

A number of other uses of petri dishes, as laboratory consumable items, are becoming explored by scientists around the world. In coming time its use is not going to be on hold or detoriate. Petri dishes have been beneficial in exploring different aspects of science, such as understanding viruses, growing cells integrated with electronic circuits, etc. It is very achievable that in near future other methods of studying organisms in lab be developed but the basic will need to culture organism in a sterile environment will in no way end and so the use of petri dishes.
