Dry Microbial Penetration Tester

The dry microbial penetration tester is mainly used to test the barrier properties of medical protective equipment (such as surgical gowns, isolation gowns, etc.), textile materials, etc. to microorganisms under dry conditions.

Structure:

It generally has a test chamber that can accommodate samples, and a control panel is equipped next to it for setting parameters. There are also components such as microbial inoculation devices and air circulation systems.

Principle:

The aerosol or suspension containing microorganisms is applied to the sample surface under a dry environment. Through specific culture and detection methods, the number of microorganisms that penetrate the sample is counted to evaluate the material's barrier ability to dry microorganisms.

Application scenarios

Medical industry: 

It is an important instrument for evaluating whether medical protective fabrics can effectively block microorganisms and ensure the safety of medical staff. Products such as surgical gowns and isolation gowns need to use this equipment to test their microbial barrier properties before leaving the factory.

Scientific research field: Researchers use it to carry out related research projects and develop new protective materials with high barrier properties.

Key points for use

Microbial safety: 

During the operation, microbial samples are involved, and biosafety regulations must be strictly followed to protect operators from microbial infection.

Calibration and maintenance: 

Calibrate the equipment regularly to ensure accurate test conditions such as air flow, temperature, humidity, etc. At the same time, maintain all components to ensure the normal operation of the equipment.
