Moisture resistant microbial penetration tester

Moisture resistant microbial penetration tester

The moisture resistant microbial penetration tester is used to measure the performance of the material to resist the bacterial penetration in the liquid when it is subjected to mechanical friction (the shielding performance of the mechanical friction chamber against the penetration of bacteria carried by the liquid); it is mainly used for medical operation orders, operating clothes and clean clothes, etc

Main uses

It is used to measure the performance of the material to resist the bacterial penetration in the liquid when it is subjected to mechanical friction (the shielding performance of the mechanical friction chamber against the penetration of bacteria carried by the liquid); it is mainly used for medical operation sheet, operating clothes and clean clothes, etc.

working principle

Put the test piece on the agar culture dish, put a piece of bacteria with the same specification on the test piece, and cover it with a piece of high-density polyethylene film about 10 microns thick. Use a conical steel ring to clamp the three layers of materials (the test material is at the bottom, the bacteria piece is in the middle, and the high-density polyethylene film is on the top of Zui). The ring kit is placed on the agar culture dish on the turntable, and the test finger can be on the surface of the whole culture dish The material is subjected to the combined action of pressure and friction by moving upward, so as to simulate the possible stress of barrier material and microbial penetration under wet condition in practical application. The microorganism on the plate will migrate to the surface of agar medium after penetrating the test material. The penetration performance of the test material can be quantitatively evaluated by culturing the agar plate and counting the colonies.

features

1. The rotation time of turntable is controlled by timer automatically.

2. The experiment refers to the lateral reciprocating operation from the center of the rotating agar dish to the periphery under the guidance of a rotating outer wheel.

3. Test means that the force applied to the material is adjustable.

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

Technical index

1. Turntable speed (60 ± 1) rpm

2. Test refers to the pressure on the material (3 ± 0.02) n

3. The speed of outer wheel is 5-6 rpm

4. The setting range of timer is 0 ~ 99.99min

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