Product Details
Sampling requirements:
Fix the six stage sieve air impact sampler on the sampling vehicle and place it at a distance of 1.0m from the ground in the center of the aerosol chamber. The sampling flow rate is 28.3L/min, and the sampling time is determined based on the prediction experiment (generally, the control group and the experimental group are sampled for 5-10 seconds before disinfection treatment, and the disinfection effect of the experimental group is evaluated after disinfection. If the disinfection is qualified, the sampling time is 5-10 minutes).
The volume size of the environmental compartment is 30m ³， The height should not be less than 2m, and the recommended size is 3.5mX3.4mx2.5m. The uniformity shall not be less than 80%, and a circular arc transition of not less than 100mm shall be used at the intersection of the two planes. It is recommended to use chemically inert, non adsorption stainless steel material with a grade of 304 or above and a surface smoothness of 2B or above for the inner wall.
Cultivation and observation of results:
After sampling, remove the plate aseptically and incubate it in a 36 C ± 1 C incubator for 48 hours for viable bacterial count. After completing the sampling of the experimental group and the positive control group, the unused batch of culture medium will be cultured simultaneously with the above two samples as the negative control. If there is bacterial growth in the negative control group, it indicates that the culture medium used is contaminated, and the test is invalid. Replace the sterile equipment and proceed again.
Disinfection test aerosol chamber: The aerosol chamber should be constructed of smooth, corrosion-resistant, and easy to clean materials such as stainless steel or aluminum alloy and glass. Two adjacent aerosol chambers (each with a volume of 20 m3) should be used, one for disinfection test and the other for test control. The environment (including temperature, humidity, lighting, airtightness, and ventilation conditions) of the two aerosol chambers should be consistent. Temperature and humidity regulating devices, as well as ventilation fan filtration and sterilization or other disinfection devices and corresponding pipelines should be installed. In addition, windows for sleeve operation and sample transfer for spray bacteria infection and sampling shall be opened.
1. The testing space is 1m3.
2. The bacterial aerosol chamber insulation system uses constant temperature and humidity for insulation.
3. The aerosol chamber has independent air supply, exhaust, and system, which can maintain a clean, enclosed, and environment.
4. The internal joints of the test cabin are sealed with environmentally friendly sealant (ensuring no volatilization or adsorption) to ensure that there is no air exchange between the air inside and outside the cabin.
5. Install independent mixing fans in the testing space to improve room temperature and uniformity of pollutants, but the mixing circulation device
The motor part adopts imported non release sealing rings to avoid polluting the testing space.
