Laboratories can be classified according to different standards such as function, application field and equipment facilities. The main types include:

Chemical laboratory: A laboratory dedicated to chemical reactions, analysis and testing, equipped with relevant chemical analysis instruments and experimental equipment.

Biological laboratory: A laboratory used for biological research, including microbiology, molecular biology, cell biology and other fields, often equipped with incubators, centrifuges, microscopes, etc.

Physical laboratory: Used for physics experiments to study physical phenomena and physical laws.

Medical laboratory: Used for clinical examination, disease diagnosis and medical research, common equipment includes microscopes, chemical analyzers, blood analyzers, etc.

Environmental laboratory: Focuses on environmental monitoring and evaluation, usually involving the analysis of environmental samples such as air, water, and soil.

Engineering laboratory: Used for engineering technology experiments, covering multiple fields such as machinery, electronics, civil engineering, and chemical engineering.

Computer laboratory: A laboratory used in computer science, software development, hardware testing and other fields.

2. Classification according to cleanliness requirements:

Cleanroom: In order to minimize contamination during research or production, the concentration of suspended particles in the air in the environment is very low, and it is often used in semiconductor, pharmaceutical and other industries.

Ordinary laboratory: does not require strict air cleanliness standards, and is suitable for most scientific research activities that do not require high cleanliness.

3. Classification according to risk level:

BSL-1 laboratory: used for low-risk biological research, not involving pathogenic microorganisms.

BSL-2 laboratory: used for medium-risk biological research, usually involving some potentially harmful but non-lethal pathogens.

BSL-3 laboratory: used for high-risk biological research, dealing with pathogens that seriously endanger health, the laboratory must be equipped with strict safety facilities.

BSL-4 laboratory: the highest risk biological laboratory, specially used for the study of deadly infectious diseases such as Ebola, SARS, etc., the environmental requirements are extremely high, and all personnel must wear protective clothing.

4. Classification according to working methods:

Open laboratory: there is no particularly strict separation inside the laboratory, suitable for most routine scientific research work.

Enclosed laboratory: the working environment is closed, usually used for handling hazardous substances or high-risk experiments, and staff need to wear special protective equipment.

5. According to industry classification:

Pharmaceutical laboratory: used for drug research and development, production and quality control, including drug analysis, stability testing and other functions.

Semiconductor laboratory: used for integrated circuits, semiconductor materials research and development, the environment involved requires extremely high cleanliness.

Food laboratory: used for food testing, quality control and safety assessment.

Agricultural laboratory: used for agricultural research, including plant pathology, crop cultivation and other fields.

Different types of laboratories have different designs, equipment configurations and operating standards, and are usually planned and set up according to the industry they serve and the needs of the research.
