Laboratory overall planning and design

Laboratory overall planning and design

The overall working environment of the laboratory is different from the ordinary office environment. It has higher technical requirements, and different fields have different needs, and the difference is sometimes large.

Laboratory planning concept

Laboratory furniture, laboratory cabinets and other experimental furniture should meet the requirements of international standards and environmental protection. The surface materials should have the characteristics of good physical and chemical properties, corrosion resistance and easy cleaning. The structure should conform to human ergonomics and operational safety and can be effective. Improve the efficiency of the operator.

The wall of the laboratory shall be made of building materials with small surface attachment, easy cleaning and flexible separation; the laboratory floor shall be made of construction materials such as corrosion resistance, wear resistance and easy washing, and the fire resistance rating of the building shall not be lower than Grade II. The installation of fire protection facilities shall also comply with the relevant national architectural design codes. The laboratory's water tanks, sewer pipes, etc. should be resistant to acid and alkali and organic solvents, and take measures to prevent clogging and leakage.

Laboratories with different functions of cleanliness, temperature and humidity, and pressure gradient requirements should use independent fresh air, return air, and exhaust systems. The exhaust system of the fume hood should be set up independently. It is not advisable to share the air duct, and it is not allowed to borrow the fire air duct.

Standard laboratory configuration method

1. The center of the laboratory is the space for setting up the central experimental platform. Usually, the washing table is set on the longitudinal side or middle of the central experimental bench. The reagent rack is set on the table, and the universal suction hood can also be set.

2, the right side of the window to set the experimental side table, work table, sky platform, side table reagent rack, universal combination frame, hanging cabinet

3. The right side door is equipped with a fume hood, a test bench, a washing table, a drying rack, a medicine cabinet, and a locker (the position of the fume hood should facilitate the connection of the ventilation duct).

4. Safety equipment, emergency showers, eye washers, fire extinguishers, etc. are usually placed on the left and right sides of the door.

5. Set the fume hood, the experimental side table, the side table reagent rack, the washing table and the hanging cabinet on the left side of the door to install large-scale devices and equipment.

6. Place the side table, work table, side reagent rack, and place for large equipment and equipment on the left side of the window.

7. The space under the window of the window can be set to the side table, test bench and microscope table. The operation is good.

Laboratory classification scheme

In modern experimental research institutions, laboratories are usually classified according to physics, general chemistry, organic synthetic chemistry, and biology. When selecting equipment for planar design, different fields of laboratories have different requirements, and the differences are very different. Big.

When designing a chemical analysis laboratory, a central station with two sides is usually arranged in the center of the laboratory, and side tables, test benches, fume hoods, medicine cabinets, drying cabinets, etc. are arranged on both sides, and a clean bench and a constant temperature and humidity device are provided as needed.

With the development of physics industries such as medicine, medicine, food, agriculture, forestry, animal husbandry, etc., in the laboratories in these fields, a highly reliable aseptic and dust-free environment is indispensable. In biological laboratories, consider the special requirements of the data processing workflow from general to inspection, testing, photography, and washing. Washing and drying stations can usually be adjusted at the entrance.

On the central table and the side table, a reagent rack and a gimbal are installed to place the reaction tube according to different experimental purposes, the extraction tube and the like, and the special gas piping to be introduced on the test bench, and the water supply and drainage for cooling. Tube, gimbal can also be installed inside the fume hood.

In order to facilitate the operation and use of the analytical instrument, the center of the laboratory is often equipped with a single-sided instrument table, the external wall is equipped with a test bench, and the piping for the special gas used in the analytical instrument should be as close as possible to the analytical instrument.

International laboratory standard chart

When planning a laboratory, you first need to understand the scale of the laboratory, taking into account various other factors:

(1) The size of the test bench and the area occupied by various devices.

(2) Configuration and operation of the test bench.

(3) Access space in the room.

(4) Issues related to daylighting.

(5) Interrelationships with other experiments or lab benches and workflow.
