Description
Bacterial filtration efficiency comprehensive tester
Bacterial Filtration Efficiency Tester
Model: RF4317
Bacterial filtration efficiency tester is used to test the filtration efficiency of bacterial filter materials such as masks or protective clothing under certain environmental conditions.
The bacterial filtration efficiency tester sends the bacterial suspension to the sampler through the sprayer, and collects the bacterial aerosol on the trypsin soybean agar. Incubate the agar plate in a certain temperature environment for a certain period of time, and then count the colony forming units formed by the bacterial particle aerosol and use a conversion table to convert it to the number of possible impact particles. The converted value is used to determine the average level of bacterial particle aerosol delivered to the test sample.
RF4317 tester, including vacuum pump, peristaltic pump, sprayer, two-way six-stage Andersen collision sampler, etc.
Scope of application Medical surgical masks, disposable medical masks, etc.
