【 Principle 】

Protein peptone provides nutrition for repairing damaged microorganisms, improving the survival rate of live bacteria, and avoiding excessive proliferation at low concentrations; Sodium chloride maintains equilibrium osmotic pressure.

Main components

Composed of peptone, sodium chloride, and distilled 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.

This product is a disposable product.

Routine sampling in ordinary clean environments: sampling from unsterilized clean countertops and laboratory workstations, gently protecting bacterial cells, used for basic monitoring of total bacterial count.

Hygiene sampling of clean areas in food production: Sampling of food packaging equipment and sterile workstations, and mild recovery of microorganisms under mild stress with low concentration tryptone.

Screening of non disinfection points in public environments: Sampling of routine contact surfaces in shopping malls and campuses, stable transportation of live bacteria in scenarios without disinfectant residue.

Basic environmental monitoring of drug clean area: Sampling of non disinfected surfaces in the pharmaceutical auxiliary area, in compliance with the standard microbiological recovery and transportation requirements of the pharmacopoeia.

Recovery of bacterial strains on the surface of laboratory equipment: washing and transporting residual bacteria on the surface of experimental consumables and inoculation equipment, and maintaining short-term survival of bacterial cells with micronutrients.

Sampling of lightly cleaned medical areas: Sampling of clean tabletops and accompanying facilities in ordinary wards, balancing osmotic pressure stability and simple bacterial protection.
