Wet resistance microbial penetration tester / particle resistance tester is used to evaluate the performance of related product materials when they are blocked by mechanical friction in the liquid, to detect whether the product meets the standard level.
When testing the wet resistant microbe penetration tester / micro-particle tester, first place the test sample on an agar Petri dish, put a piece of bacteria of the same specification on the test sample, and then cover a piece with a thickness of about 10 microns High-density polyethylene membrane, use a conical steel ring to clamp the three layers of material (the test material is at the bottom, the fungus piece is centered, and the high-density polyethylene membrane is at the top) together. Place the ring kit on the agar Petri dish on the turntable plate , The test refers to acting on the material in a way that can move across the surface of the Petri dish, subjecting the material to the combined effect of pressure and friction, in order to simulate the possible stress conditions and wet conditions of the barrier material in the actual application process Microbe penetration. After penetrating the test material, the microorganisms on the bacterial sheet will migrate to the surface of the agar medium. By culturing the agar Petri dish and counting the colonies, the penetrating performance of the test material can be quantitatively evaluated.
