【 Principle 】

Potassium dihydrogen phosphate provides acidic buffering for the components of the buffer system, dissociating H ₂ PO ₄⁻, which can neutralize alkaline impurities in the system and resist pH rise; Sodium hydroxide is used to adjust the pH of the system to neutral and forms a buffer pair with potassium dihydrogen phosphate, without neutralizing disinfectant function.

Main components

Composed of potassium dihydrogen phosphate, sodium hydroxide, and distilled water.

Storage conditions and expiration date

Storage conditions: This product should be stored in a dark environment at 2-8 ℃.

Validity period: The unopened original packaging has a validity period of 6 months.

This product is a disposable product.

Dilution of samples without disinfection residue: used for diluting clean water samples, bacterial strains, etc., stabilizing pH, and preparing bacterial suspensions.

Clean instrument sampling and washing: Rinse unsterilized instruments or consumables for microbiological limit testing.

Sample processing for testing: Dilute samples such as cells and secretions, maintain neutral pH, and prevent cell inactivation.

Physicochemical and pH control experiment: As a blank control solvent, stabilize the acidity and alkalinity of the system.

Baseline sampling in non disinfected environments: Evaluate the background microbial levels in clean areas in an unsterilized state.

Quality control blank control: Verify the sterility of the buffer and eliminate reagent interference.
