How to choose a Dry microbial penetration tester?

The Dry microbial penetration tester is used to determine the resistance of a material to bacterial penetration of dry particles in the size range of human dander. The test is carried out by immobilizing the sample on a container.

 

Dry microbial penetration tester meets criteria:

 

YY/T0506.5-2009 "Surgical drapes, gowns and clean clothes for patients, medical staff and instruments - Part 5: Test method for resistance to penetration of dry microorganisms"

ISO 22612:2005 "Test method for resistance to penetration of dry microorganisms by protective clothing for infectious agents"

 

Dry state microbial penetration performance tester technical parameters:

 

1. Vibration form: pneumatic ball vibrator

 

2. Vibration frequency: 20800 times/min

 

3. Vibration force: 650N

 

4. Workbench size: 40cm×40cm×10mm

 

5. Workbench medium: marble slab

 

6. Experiment container: stainless steel experiment container

 

7. Working position: 6

 

8. Equipped with biological safety cabinet

 

8.1. The biological safety cabinet adopts negative pressure on all sides, that is, the left and right sides, rear and bottom walls of the whole device are all negative pressure air ducts, so that the working area and the external environment form an air curtain and double-layer isolation of the box, and work at the same time. The area is surrounded by negative pressure to ensure that the sample does not leak.

 

8.2. Biosafety performance: personnel safety, the number of microbial colonies in the impact sampler is ≤10CFU/time, and the number of colonies in the slit sampler is ≤5CFU/time

 

8.3. Airway tightness: the airway of the device is under the pressure of 500Pa for 30 minutes, the pressure drop is less than or equal to 10%, and no bubbles appear in the penetrating part under the soap bubble test conditions.

 

8.4. Cleanliness level: 100, that is, the dust content of ≥0.5um particles per IL of air is ≤0.35

 

8.5. Noise: the height of the table, 30cm from the front window, and 38cm upwards, under the condition that the ambient noise is 55Db, the arithmetic average of the four directions is ≤58dB (A)

 

8.6, Lighting: ≥ 680LUX Front window glass: tempered, anti-ultraviolet

 

8.7, UV intensity: ≥80uw/cm2

 

8.8. Differential pressure display: (30/2) digit liquid crystal display, American GE differential pressure sensor. The number displayed on the LCD indicates the pressure loss of the filter, and the error of the differential pressure sensor is ≤5%

 

8.9. Mechanical properties: The equipment table should be able to withstand 25Kg pressure without obvious subsidence, bending and other deformation.

 

8.10. Electric strength: withstand voltage of 1500V for 1 minute without breakdown

 

8.11. Liquid collection tank: It is used to collect the splashed liquid in the working area and is equipped with a drain valve.
