2022 New Product: Medical Face Mask Synthetic Blood Penetration Resistance Teste

The Medical Face Mask Synthetic Blood Penetration Resistance Tester is suitable for the determination of the penetration performance of synthetic blood of medical masks. It can be used by medical inspection departments, safety inspection departments and scientific research units.

 

principle:

The medical mask sample was supported on the test device, and 2 mL of synthetic blood was sprayed horizontally to the tested mask from a cannula with an inner diameter of 0.84 mm at a distance of 300 mm. Simulate the scene where the mask is sprayed with blood from perforated blood vessels, and observe the penetration of synthetic blood on the other side of the mask.
