Moisture-resistant microbial penetration tester

The hygroscopic microbial penetration tester is used to measure the resistance of the material to bacterial penetration in the liquid when it is subjected to mechanical friction (the shielding performance of the liquid against bacterial penetration carried by the mechanical friction chamber). Mainly used for medical operation sheet, operating clothes and clean clothes

The main purpose

It is used to measure the resistance of material to bacterial penetration in liquid when it is subjected to mechanical friction (resistance to bacterial penetration of liquid carried by mechanical friction chamber). Mainly used for medical operation sheet, operating clothes and clean clothes.

The working principle of

Will be put on the AGAR plate specimen, one the same specifications of the bacteria in the specimen, and then cover with a piece of about 10 microns thick high-density polyethylene film, the three layers of material with steel taper ring (the test materials, bacteria piece of middle and high density polyethylene film on zui) card together, put this ring suite at potter's wheel on the AGAR plate, test means to move on the surface of the plate of the way on the material, the material of pressure and friction factors, to simulate barrier material may occur in the process of practical application of force and penetration under the condition of wet microorganisms. After penetrating the test material, the microorganism on the plate will migrate to the surface of AGAR medium. Through the culture of AGAR culture dish and colony count, the penetrability of the test material can be quantitatively evaluated.

Characteristics of the

1. The rotation of the rotary table is quiet and steady, and the rotation time of the rotary table is automatically controlled by the timer.

2. The test refers to the lateral reciprocating operation from the center of the rotating AGAR petri dish to the periphery under the guidance of the rotating outward wheel.

3. Test means that the force exerted on the material is adjustable.

4. All test components are made of corrosion resistant stainless steel.

Technical indicators

1. Rotary speed (60 ± 1) RPM

2. The test refers to the pressure on the material (3±0.02)N

3. The speed of the outward wheel is 5 ~ 6 RPM

4. Timer setting range is 0 ~ 99.99min

5. Total weight of internal and external ring weights :(800±1)g

Applicable standards

Surgical sheets, surgical gowns and cleansing suits for patients, medical personnel and instruments - part 6: test methods for hygroscopic microbe penetration

Wet-resistance microbe penetration tester/wet-resistance microbe tester for medical clothing is used to evaluate the bacterial penetration performance of materials in liquid when subjected to mechanical friction. Specifically, it is used to measure the bacterial penetration performance of materials in liquid when subjected to mechanical friction (the shielding performance of liquid against bacterial penetration carried by mechanical friction chamber). Mainly used for medical operation sheet, operating clothes and clean clothes.
