【 Principle 】

A 0.85% sodium chloride purified aqueous solution provides an isotonic environment to maintain bacterial morphology and activity, avoiding osmotic pressure damage.

Main components

Composed of sodium chloride and purified water.

Storage conditions and expiration date

Storage conditions: This product should be stored in a dark environment at 2-25 ℃.

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

Sample dilution suspension: Dilute sputum, pus, secretions and other specimens for smear microscopy observation of bacterial cells.

Sampling, washing and recovery: Wash off bacteria from the skin and instrument surface, prepare bacterial suspension for inoculation and culture.

Bacterial strain treatment and turbidity preparation: Wash bacterial cells, remove impurities, and prepare bacterial suspensions for drug susceptibility testing.

Blank control: Verify the sterility of physiological saline and exclude false positives caused by reagent contamination.

Wound flushing sampling: Rinse wounds and mucous membranes without disinfectant residue to protect fragile live bacteria.

Gradient dilution counting: used for quantitative detection of total bacterial count in water samples, raw materials, and other samples.
