Product Overview

【 Principle 】

Sodium dihydrogen phosphate+potassium dihydrogen phosphate form a buffer pair, stabilizing pH 7.2-7.4 and protecting bacterial cells from acid-base damage; Tween-80- Neutralizes phenolic and alcohol disinfectants, emulsifies residual oils, and reduces damage to bacterial cells; Sodium thiosulfate - a specific neutralizing chlorine containing disinfectant that reduces free chlorine and terminates oxidative damage to bacterial proteins and nucleic acids.

Main components

Composed of disodium hydrogen phosphate, potassium dihydrogen sulfate, Tween-80, and sodium thiosulfate.

Storage conditions and expiration date

Application Scenarios

Disinfection effect monitoring sampling: neutralize residual disinfectants on instruments, surfaces, hands, etc., avoid false negatives, and objectively evaluate disinfection effects.

Microbial testing of medical devices: residual disinfectant on the surface of sterilized/disinfected medical devices is washed out, and live bacteria are recovered to complete contamination inspection.

Environmental physical screening for nosocomial infections: Regular sampling of ICU, operating room and other areas, quantitative counting of live bacteria, and screening for sources of multidrug-resistant bacterial contamination.

Sampling after disinfection of skin and mucous membranes: neutralize residual disinfectant on the skin, accurately detect live bacteria, and evaluate the effectiveness of hand disinfection.

Disinfection product validation test: As a specialized eluent for disinfectant performance testing, it ensures the true and effective counting of viable bacteria.

Dilution and transport protection of bacterial suspension: supports gradient dilution counting, protects damaged bacterial cells through buffering isotonic system, and reduces transport mortality.
