- Which cleanroom ISO class is suitable for liquid crystal research?
I was wondering which cleanroom ISO class is suitable for liquid crystal research?
A Cleanroom ISO Class is a classification system that measures the level of cleanliness and particle count in a cleanroom environment. It is based on the number of particles of a certain size per cubic meter of air.
Liquid Crystal research involves highly sensitive materials that can easily be contaminated by particles in the air. A cleanroom with a controlled environment helps to minimize the risk of contamination and ensures accurate and reliable results.
The main difference between Cleanroom ISO Classes is the maximum allowable number of particles per cubic meter of air. The lower the ISO Class, the cleaner the environment. For example, an ISO Class 1 cleanroom allows a maximum of 10 particles of size 0.1 micrometers per cubic meter of air, while an ISO Class 9 cleanroom allows a maximum of 9,000,000 particles of the same size per cubic meter of air.
The recommended Cleanroom ISO Class for Liquid Crystal research is ISO Class 5 or higher. This means that the cleanroom environment should have no more than 100 particles of size 0.1 micrometers per cubic meter of air. However, the specific ISO Class may vary depending on the requirements of the research and the sensitivity of the materials being used.
The Cleanroom ISO Class is determined by conducting particle count tests in the cleanroom using a laser particle counter. The results of these tests are then compared to the ISO Class standards set by the International Organization for Standardization (ISO) to determine the appropriate classification.
