General description

RINGER tablets are used for the preparation of the RINGER′S solution. Ringer Salt Solution is isotonic with bacteria and thus prevents them from being subjected to osmotic stress when they are removed from their customary environment. It is physiologically superior to physiological saline for sensitive organisms and preserves the cells in their original condition. The salts in the medium balance the osmotic equilibrium of the medium, thereby protecting the organisms from osmotic stress caused due to change in the environment.

Application

RINGER tablets are used for the preparation of the RINGER′S solution, which is used as an isotonic diluent for food, milk, and dairy products during the microbiological examination. RINGER solution is utilized like a diluent for preparing suspensions in bacteriological studies, especially in the examination of milk and dairy products.
