surgical operation clothig wet penetration tester

Application:

Face mask wet microbial penetration resistance tester used to measure the penetration performance of bacteria in the liquid when the material is subjected to mechanical friction (the shielding performance of the liquid against bacterial penetration by the mechanical friction chamber); It is mainly used for medical operation, operating clothes and clean clothes, etc.

Wet-penetration-test exporter Standards:

YY/T 0506.6-2009 Surgical drapes, gowns and clean air suits, used as medical devices, for patients, clinical staff and equipment-Part 6:Test method to determine the resistance to wet bacterial penetration

Principles:

Place the specimen on AGAR plate. A piece of the same specification is placed on the specimen. Cover with a high density polyethylene film about 10 microns thick. The three layers of material using the cone steel ring (the test material below, the mushroom center, high density polyethylene film on top) are stuck together. Place the ring on the AGAR plate on the turntable. The experiment means that the material can be applied to the material in a way that can be moved on the surface of the whole plate, so that the material is subjected to the combination of pressure and friction.

This model can simulate the force condition of the barrier material in the actual application and the microorganism penetration under the wet conditions.

The microbes on the microbial migrate to the surface of the AGAR plate after penetrating the experimental material. Through the culture and colony count of AGAR plate, the penetration performance of the test material can be quantitatively evaluated.
