The decoration of the bioengineering laboratory, the laboratory planning concept: various laboratory benches, laboratory cabinets and other laboratory furniture in the laboratory should meet the requirements of standards and environmental protection, and the surface materials should have good physical and chemical properties, corrosion resistance, acid and alkali resistance, and easy cleaning. Features, the structure should be in line with ergonomics and safe operation, can effectively improve the operator's work efficiency, while ensuring the personal safety of experimenters. The wall of the laboratory clean engineering should be made of color steel plates with low surface adhesion, convenient cleaning, and flexible separation; the laboratory floor should be made of corrosion-resistant, wear-resistant, and easy-to-wash building materials, and the building fire resistance rating should not be lower than Class II , The setting of fire-fighting facilities should also comply with the regulations of my country's relevant building design codes. Laboratory sinks, sewer pipes, etc. should be resistant to acids, alkalis and organic solvents, and take measures to prevent clogging and leakage. A laboratory with different functions such as cleanliness, temperature and humidity, and pressure gradient requirements should use separate fresh air, return air, and exhaust air systems. The exhaust system of the fume hood should be set up separately, it is not advisable to share the air duct, let alone the fire air duct
