Anti-humidity microbial penetration tester
The moisture barrier microbial penetration tester is used to determine the performance of the material to resist the penetration of bacteria in the liquid when it is subjected to mechanical friction (the shielding performance of the mechanical friction chamber against the penetration of liquid-carrying bacteria); it is mainly used for medical surgical drapes, surgical gowns and Clean clothes etc.
The main purpose
It is used to determine the material's ability to resist the penetration of bacteria in the liquid when subjected to mechanical friction (the shielding performance of the mechanical friction chamber against the penetration of liquid-carrying bacteria); it is mainly used for medical surgical drapes, surgical gowns and clean clothes, etc.
Working principle
Put the test piece on the agar petri dish, put a piece of the same size of the bacteria on the test piece, and then cover a piece of high-density polyethylene film about 10 microns thick, use a tapered steel ring to divide the three layers of materials (the test materials are below) , The bacterial sheet is in the center, and the high-density polyethylene film is on the top), and the ring set is placed on the agar petri dish on the turntable. The test refers to acting on the material in a way that can move on the entire surface of the petri dish to make the material Under the combined effect of pressure and friction, it can simulate the force of the barrier material and the penetration of microorganisms under wet conditions in the actual application process. After the microorganisms on the bacterial sheet penetrate the test material, they will migrate to the surface of the agar medium. The penetration performance of the test material can be quantitatively evaluated by culturing the agar petri dish and counting the colony.
Feature
1. The turntable rotates quietly and smoothly, and the rotation time of the turntable is automatically controlled by a timer.
2. The test means that it is guided by the rotating outward wheel and can reciprocate sideways from the center of the rotating agar petri dish to the periphery.
3. The test means that the force exerted on the material is adjustable.
4. The test parts are all made of corrosion-resistant stainless steel.
Technical index
1. Turntable speed: (60 ± 1) rpm
2. The test refers to the pressure on the material: (3±0.02)N
3. Rotation speed of outward wheel: 5~6 rpm
4. Timer setting range: 0~99.99min
5. Total weight of inner and outer ring weights: (800±1)g
