Indoor clear height: the indoor clear height of conventional laboratories and research studios: when no air conditioning is set, it should not be lower; When setting the air conditioning, it should not be lower.

The clear height of the walkway should not be lower. The indoor clear height of the special laboratory shall be determined according to the requirements of the size, installation and maintenance of experimental instruments and equipment. Laboratory Bench Layout:

Common test benches include ruler island type or peninsula type ** test bench, side test bench. It is not advisable to arrange the side test bench against the external wall of the window, and the island or peninsula ** test bench should not be arranged parallel to the external window. When it must be arranged parallel to the exterior window, the clear distance between it and the external wall should not be less.

According to the different requirements of users and the principle of ergonomics, we make full use of the environmental space and carefully design the laboratory to build a more safe, humanized and environmentally friendly laboratory, which fully embodies the principle of ergonomics. Boldly explore research and development in the fields of green laboratory design and laboratory intelligent control, and the basis of people-oriented laboratory planning and design. In order to make our professional and service to reach the tailor-made level, a safe and comfortable laboratory construction environment is our common pursuit.

When arranging the detoxification cabinet or experimental equipment, the net distance between it and the laboratory bench should not be less than. The clear distance between the end of the bench and the walkway wall should not be less.

Door: The width of the door opening of the laboratory consisting of 1 2 standard units should not be less than 1m and the height should not be less than. The width of the door opening of a laboratory consisting of one or more standard units should not be less than and the height should not be less than.

The size of the door opening for rooms with special requirements should be determined on a case-by-case basis. The door of the laboratory should be provided with an observation window.

The general depth of the laboratory ** table is 1500mm, and the depth of the experimental side table is 750mm.

The general height of the laboratory workbench is 760mm and 840mm, 760mm is operated by sitting Lingkai, and 840mm is operated by standing, depending on personal preference; The length of the laboratory bench is generally a multiple of 750mm, preferably no more than 4500mm.

Side table: length and width 75cm and height 80cm.

**Table: length and width 150cm and height 80cm.

The length is generally customized, generally a multiple of 75cm, not more than 450cm.

The structure of the standard laboratory is composed of:

The main types of test benches are: all-steel structure test bench, steel-wood structure test bench, aluminum-wood structure solid core Wang rot test bench, all-wood structure test bench, PP structure test bench and other types.

Experimental hospitals, schools, chemical plants, scientific research institutes and other enterprises and institutions.

A table used to perform experiments and store instruments.

According to the position of the place, it is divided into: ** actual correction leakage inspection table, side test table, corner table.

According to the material, it is divided into: all-steel test bench, steel-wood test bench, all-wood test bench, PP test bench, aluminum-wood test bench (basically eliminated now). There are also some tall cabinets: fume hoods.

Medicine cabinets, utensils cabinets, gas cylinder cabinets, explosion-proof cabinets, glass cabinets, etc.

1. Basic requirements for the design and planning of chemical laboratories.

The design of the chemical laboratory should meet the requirements of workflow, design specifications and space standards, and be closely integrated with the layout of detoxification cabinets, laboratory benches and experimental instruments and equipment, structural selection and pipeline space layout. The basic requirements for the design of various chemical laboratories are as follows:

1. For the chemical laboratory with a small area, the side table is used with an entrance, and for the chemical laboratory with a larger area, more than one table can be used with more than two entrances and exits; It is necessary to ensure that the entrance and exit are unobstructed, and there are no dead corners in the passage.

2. For the laboratory with local ventilation, a universal smoke exhaust hood can be used; Laboratories that use volatile substances or mail solvents in large quantities must be equipped with a detox cabinet or tabletop ventilated hood located away from the entrance and near the tube well.

3. Reagent cabinets, utensils cabinets and other functional high cabinets are located against the wall, and the utensils cabinet should be as close to the sink as possible, and the reagent cabinet needs to be equipped with an exhaust device.

4. The experimental table is required to be resistant to strong acid and alkali corrosion and high temperature, and it is recommended to use epoxy resin table top and epoxy resin sink.

5. According to the different nature of the experiment, it can be equipped with three-mouth faucet, pure water faucet, suction filter faucet, waste liquid collection bin, trash can, bottle washer, eyewash, emergency shower and other accessories or acid cabinet, explosion-proof cabinet and other safety storage cabinets.

6. The reagent rack can be made of steel reagent rack with anti-corrosion layer such as frosted glass or glass solid core physical and chemical plate, and the height can be adjusted, and the reagent rack can also be equipped with a hanging cabinet.

7. The oven is too set to be far away from the use or storage of organic solvents.

8. It must meet all the requirements of (experimental area space standards).

2. Basic requirements for the interior decoration of chemical laboratories.

1. Ground: The floor of the laboratory is required to be non-slip, corrosion-resistant, and easy to clean, and non-slip ceramic floor tiles, PVC flooring or special flooring for King Kong laboratory can be used.

2. Partition: The wall can be made of semi-glass wall or floor-to-ceiling glass wall, and the semi-glass wall can be combined with glass and color steel plate, glass and calcium silicate board, glass and brick wall.

3. Ceiling: For laboratories with low floor height, it is recommended not to do ceiling, and for the above laboratories, aluminum gusset ceilings can be used. For laboratories partitioned with color steel plates, color steel plates are used for ceilings. Ceilings require simple and easy cleaning.

4. Door: The door of the laboratory can be made of steel door, color steel plate door, glass door, etc., in the form of a mother and son door, the door is equipped with an observation window, the door is open outward, and the access control can be equipped with an electronic access control system and warning signs.

3. Ventilation system engineering of chemical laboratory.

1. The laboratory needs good ventilation, and the ventilation and detoxification devices used in the laboratory mainly include detoxification cabinets, directional exhaust hoods and desktop ventilation hoods, and the design of detoxification cabinets, universal smoke exhaust hoods and desktop ventilation hoods should be reasonable, and the convenience of operation should be considered and energy saving should be considered, and air conditioning should be set up if necessary.

2. For small laboratories with few detoxification cabinets, the control of the detoxification cabinet can be controlled separately, that is, each fan controls a detoxification cabinet, in this exhaust system, a single air flow will not affect each other with other air flows, and the fan closure will only affect one detoxification cabinet.
