RINGER tablets (catalogue No. 1155250001) are compressed tablets formulated to yield RINGER’S solution, an isotonic buffer used to maintain osmotic balance for micro-organisms during suspension preparation and microbiological analysis of food, dairy and other samples. The solution simulates physiological conditions, preventing bacterial stress during handling and analysis.
RINGER tablets, catalogue No. 1155250001, are dehydrated salt tablets intended for preparation of RINGER’S solution, an isotonic aqueous diluent that maintains cells and bacteria under near-physiological conditions during microbiological sample preparation. The formulation includes balanced inorganic salts that support osmotic equilibrium, reducing osmotic stress on organisms when they are transferred from their native environments into test systems. RINGER’S solution is commonly used in microbiological testing of food and dairy products, allowing accurate enumeration and analysis of bacteria.
Advantages
- Pre-formulated tablet format ensures reproducible and consistent RINGER’S solution preparation.
- Isotonic formulation helps maintain integrity of microbial cells during sample preparation.
- Suitable for food, dairy and beverage microbiological examination.
- Compact tablet form simplifies storage, dosing and handling in laboratory workflows.
