Laboratory Corona Treater for Petri Dish

A corona treater for Petri dishes is a device used for surface treatment of Petri dishes made of plastic materials such as polystyrene or polypropylene. Petri dishes are commonly used in the laboratory for growing microorganisms or for cell culture applications. The corona treater is used to improve the surface properties of the Petri dish, which is important for ensuring optimal growth of microorganisms or cells.
The corona treater operates by passing the Petri dish under a corona discharge electrode, which generates a plasma that interacts with the surface of the dish. The plasma modifies the surface properties of the dish, improving its wettability and adhesion properties. This ensures that the growth medium adheres properly to the surface of the dish, which promotes optimal growth of microorganisms or cells.
