Overview

20m Prepare bacterial suspension in the air chamber Take fresh culture of Staphylococcus aureus (8032) (3rd to 8th generation) on nutrient agar medium slant (18 h~24 h), and use a 5.0ml pipette to aspirate 3.0mL~5.0mL. Add nutrient broth to the slant tube, repeatedly blow and aspirate, wash off the bacterial coating, filter with sterile defatted cotton, and dilute with nutrient broth into a test bacterial suspension with a concentration of 5X10 * CFU/mL~3X10'CFU/mL.

7 adjacent pairs of aerosol cabinets or chambers, one for disinfectionToxicity test - one for experimental control. -Regarding aerosols

The environment in which the cabinet or aerosol chamber is located(including temperature, humidity, lighting, airtightness, and ventilation conditions) should be consistent. Cabinets (or rooms) should be constructed with aluminum alloy and glass. Temperature and humidity regulating devices, ventilator filtration and sterilization or other disinfection devices and corresponding pipelines shall be installed. In addition, windows such as sleeve operation and sample transmission for spray bacteria, disinfectant and sampling shall be set up.

20m ³ air chamberThis standard specifies the raw material requirements, technical requirements, inspection methods, usage methods, label instructions, and precautions for disinfectants used for indoor air disinfection. This standard is applicable for the main purpose of killing microorganisms in the airAn indoor air disinfectant that meets disinfection requirements.
