The main purpose

The anti-dry microbial penetration experiment system is composed of air source generation system, detection body, control system and other parts. It is used to perform anti-dry microbial penetration test methods on surgical drapes, surgical gowns and clean clothes.

Scope of application

Dry microbial penetration resistance tester/Dry microbial resistance tester is used to determine the resistance of the material to the penetration of bacteria on dry particles within the size range of human dander. During the test, the sample is fixed on a container.

Main description

   The dry microbial penetration resistance tester/dry microbial resistance tester is specially used to determine the resistance of materials to the penetration of bacteria on dry particles within the size range of human dander.

   During the test, the samples are fixed on a container respectively. Among these containers, 5 containers carrying Bacillus subtilis talc powder, and 1 container with uncontaminated talc powder as a control. Insert a petri dish at the bottom of each container close to the time below.

   The equipment supporting the container is oscillated by a gas ball oscillator, all the talcum powder penetrating the sample falls on the petri dish, and the petri dish is removed for culture. The results of the experiment were evaluated by counting the growing colonies.
