What are the purification standards for the laboratory?

2023-10-28 10:41

The purification standards required for laboratories may vary depending on the specific laboratory type, experimental needs, and experimental projects carried out. The following are some common laboratory purification standards and requirements:

1. Air cleanliness: According to the needs of the laboratory, commonly used cleanliness levels include ISO 5 (high cleanliness) to ISO 9 (low cleanliness) in the ISO 14644-

1 standard. Higher levels of cleanliness require stricter air filtration and particle control to ensure the accuracy and repeatability of experiments.

2. Static electricity control: Some experiments often conducted in the laboratory require controlling the generation of static electricity and preventing static discharge, so it is often necessary to take appropriate static electricity control measures in the laboratory, such as grounding systems, anti-static flooring, and anti-static equipment.


3. Temperature and humidity control: Some laboratories need to maintain constant temperature and humidity conditions to prevent changes that affect experimental results. In these laboratories, appropriate temperature and humidity control equipment and systems need to be configured to maintain stable environmental conditions.

4. Clean work area: A laboratory usually needs to establish a clean work area, such as a clean desk, clean room, or clean operation desk. These working areas should meet certain cleanliness requirements to ensure a sterile and dust-free environment for experiments.

5. Equipment and instrument purification: The laboratory needs to undergo regular equipment and instrument purification to ensure that its surface is dust-free and sterile, and to reduce the risk of experimental pollution. This includes regular cleaning and disinfection of equipment, use of clean laboratory equipment and reagents, etc.

It should be noted that the purification standards and requirements vary depending on the type of laboratory, experimental projects, and relevant industry norms. During the construction and operation of the laboratory, corresponding purification standards should be formulated based on specific needs and relevant standards, and operators should strictly abide by and implement these standards to ensure the reliability of the laboratory's purification environment and experimental results.
