【 Principle 】

Sodium chloride maintains equilibrium osmotic pressure; Potassium dihydrogen phosphate and sodium dihydrogen phosphate are phosphate buffering agents that stabilize the pH value of the sampling solution.

Main components

Composed of sodium chloride, potassium dihydrogen phosphate, sodium dihydrogen phosphate, 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 environmental microbial background sampling: Basic bacterial colony sampling on the surfaces of clean workshops, office areas, and ordinary workstations, used for daily environmental hygiene baseline monitoring.

Cleanliness sampling of sterile items: Sampling of the outer surface of the packaging and the contact surface that has not been disinfected and cleaned. When there is no need for neutralization, simply wash out microorganisms for counting.

Basic hygiene screening for food processing: Sampling of dry and clean production countertops and packaging equipment, and recovery of surface attached live bacteria in scenarios without disinfectant residue.

Sampling in non disinfected areas of clinical practice: Clean the tabletop of the ward and collect samples from accompanying facilities, only requiring stable bacterial osmotic pressure and simple transportation for testing.

Basic monitoring of public environment: Routine survey of public contact surfaces in shopping malls and campuses, suitable for general hygiene sampling without strong disinfection residues.

Bacterial washing and transportation assistance: Recovery of target bacteria on the surface of laboratory equipment, relying on a buffer system to stabilize pH and osmotic pressure, and protect bacterial survival.
