YS-730D Dry Microbial Penetration Tester
【Scope of Application】:
Bacteria can penetrate barrier materials via dry organic/inorganic particles (e.g., bacteria-carrying skin flakes through surgical gowns, or particles through packaging). This tester determines material resistance to penetration by bacteria carried on dry particles within the size range of human skin flakes.
【Compliant Standards】:
1. ISO 22612 Protective clothing — Protection against infectious agents — Test method for resistance to dry microbial penetration
2. YY/T 0506.5-2009 Surgical drapes, gowns and clean air suits for patients, clinical staff and equipment — Part 5: Test method for resistance to dry microbial penetration
【Instrument Features】:
1. Biosafety cabinet provides sterile, particle-free workspace.
2. Equipped with lighting and UV sterilization.
3. Reliable, stable testing; low noise (≤65dB).
4. Front-opening glass door for easy operation/observation.
5. Removable stand; adjustable feet + 4 auxiliary casters for mobility.
6. Biosafety cabinet exhaust system; HEPA inlet/outlet for safety.
7. Fully touchscreen interface; user-friendly.
8. Stainless steel test vessels; easy cleaning.
