Moisture resistant microbial penetration tester

Moisture resistant microbial penetration tester

Applicable scope:

This equipment is specialized in evaluating the performance of materials in resisting bacterial penetration in liquids when subjected to mechanical friction. Specifically, it is used to measure the performance of materials in resisting bacterial penetration in liquids when subjected to mechanical friction (the shielding performance of the mechanical friction chamber against bacterial penetration in liquids); Mainly used for medical surgical sheets, surgical gowns, and clean clothing.

Meets standards:

YY/T 0506.6, EN ISO 22610

Testing principle:

Place the test piece on an agar culture dish, with a piece of bacteria of the same specification placed on top of the test piece. Cover it with a high-density polyethylene film about 10 microns thick, and use a conical steel ring to clamp the three layers of material (the test material is at the bottom, the bacteria are in the center, and the high-density polyethylene film is on the top) together. Place this ring kit on the agar culture dish on the turntable, and the test finger acts on the material in a way that can move on the entire surface of the dish, causing the material to be subjected to the combined effect of pressure and friction, in order to simulate the possible stress and microbial penetration of the barrier material under wet conditions in practical applications. After the microorganisms on the agar plate penetrate the test material, they migrate to the surface of the agar medium. By culturing the agar plate and counting the colonies, the penetration performance of the test material can be quantitatively evaluated.

Product features:

1. The turntable rotates quietly and steadily, and the rotation time of the turntable is automatically controlled by a timer.

2. The experiment refers to the lateral reciprocating movement from the center of the rotating agar culture dish to the periphery, guided by a rotating outer wheel.

3. The experiment refers to the adjustable force applied to the material.

4. The test components are all made of corrosion-resistant stainless steel.

Instrument parameters:

1. Rotary speed 60 rpm ± 1 rpm

2. The test refers to a pressure of 3 N ± 0.02N on the material

3. Outer wheel speed 5-6 rpm

4. Timer setting range 0-99.99min

5. Total weight of inner and outer ring weights: 800g ± 1g
