Dry microbial penetration resistance tester DMPRT GT-RA14
Application
The Experimental system of microbial penetration in dry state is composed of gas source generation system, detection main body, control system and so on. It is used to carry out the method of dry microbe penetration resistance test on the surgical drapes, gowns and clean air suits.
Principle
- 1.The test is carried out on test pieces each fixed in a container. In every container except one a portion of talc contaminated with Bacillus subtilis is poured on the test piece. One container is left uncontaminated as a control. A sedimentation plate is inserted at the base of each container at a short distance below the test piece.
- 2.The apparatus supporting the containers is then vibrated by a pneumatic ball vibrator. The talc that penetrates is captured on the sedimentation plate. The sedimentation plates are removed and incubated.
-
3.Dry microbial penetration resistance tester DMPRT: The numbers of colonies produced are counted.
