【 Principle 】

Sodium chloride maintains isotonic protection of bacterial integrity, while phosphate buffering stabilizes pH 7.2-7.4 to avoid acid-base damage leading to false negatives.

Main components

Composed of sodium chloride, disodium hydrogen phosphate, and potassium dihydrogen sulfate.

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.

This product is a disposable product.

Sample dilution and pre-treatment for microscopy: Dilute sputum, pus, secretions, and other specimens to disperse bacterial cells for staining microscopy.

Instrument sampling and washing: Wash away instruments and live bacteria on the skin surface without disinfectant residue, for inoculation and culture.

Preparation of drug sensitive bacterial suspension: Adjust the MacLehose turbidity, maintain bacterial activity and pH, and ensure stable drug sensitivity results.

Strain washing and short-term storage: Clean bacterial impurities and buffer system to reduce bacterial death caused by metabolic acid production.

Quantitative gradient dilution: used for quantitative counting of total bacterial count and pathogenic bacteria in water samples, raw materials, and other samples.

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