Dry state microbial penetration tester

Dry state microbial penetration tester

The dry state microbial penetration performance tester is specialized in measuring the bacterial penetration performance on dry particles within the range of material impedance and human dandruff size. During testing, the samples are fixed on separate containers. Among these containers, 5 containers carried Bacillus subtilis talc powder, and 1 container added unstained talc powder as a control. Insert one culture dish at the bottom of each container close to the time below.


The equipment supporting the container is oscillated by a gas ball oscillator, and all the talc powder penetrating the sample falls onto the culture dish, removing the culture dish for cultivation. Evaluate the experimental results by counting the growing colonies.
