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 3 months.

This product is a disposable product.

Gradient dilution of specimens: gradient dilution of food, water samples, and environmental smear samples, used for colony counting.

Preparation of bacterial suspension: Scrape and dilute the agar/slant bacterial moss to prepare the bacterial solution for drug sensitivity, biochemical and other experiments.

Sample homogenization and elution: Solid food and utensil wiping samples are homogenized by adding physiological saline to elute attached microorganisms.

Sample washing and dilution: Pharyngeal swabs, wound swabs, etc. are used to wash away bacterial cells and improve detection rates.

Smear staining rinsing: Rinse the glass slide during bacterial smear and Gram staining processes to remove excess staining solution.

Strain cleaning and purification: Centrifuge and wash the bacterial cells to remove residual culture medium and metabolic impurities.
