Detailed technical knowledge

Laboratory design ideas:

1.1 Design focus

(1) Set according to the analysis method: physical and chemical analysis, instrument analysis, special item analysis, etc;

(2) Set according to the nature of work: research and development, testing, pilot production, etc;

(3) Set by purpose: cytological analysis, biological analysis, zoological analysis, physical and chemical analysis, etc.

1.2 Layout of design

There are many types of laboratory layout, such as one-way single channel laboratory layout, mouth-shaped double aisle laboratory layout, large room and small room laboratory layout and hybrid laboratory layout, which can be selected according to the specific situation.
It is recommended to consider the layout according to the actual working process of the laboratory or the centralized setting of the experimental rooms for the same purpose. Different experimental rooms (areas) are arranged in order to complete different experimental operations, and each experimental room (area) is arranged according to the order of experimental operations. The specific work flow can be arranged according to the following: sample flow, waste logistics (toxic waste logistics).

1.3 Design of buildings and utilities

The qualitative determination of buildings, civil or production, depends on the specific purpose of the laboratory.
The building design shall consider the layout of the laboratory according to the relevant requirements in the code for fire protection design of buildings, and pay attention to the use of organic solvents in the laboratory. The consumption of organic solvents is closely related to the layout of the laboratory or the qualitative nature of the building, and shall be designed with reference to the relevant provisions in the code for fire protection design of buildings.
If it is an old plant reconstruction project, the floor load of heavy load rooms such as large sterilization cabinets and archives and reference rooms should be rechecked.
HVAC design is one of the key points of laboratory design, mainly including ventilation and air conditioning, and it is also one of the key contents of laboratory energy-saving design.
There are two ways to design the gas source: one is centralized supply in the park or plant area, and the pipeline is directly connected to the point of use; The other is to supply gas from the gas cylinder, which is set in the cylinder room and sent to the gas consumption point through the manifold.
There are two ways to connect the utility pipelines in the experimental area: one is to route in the floor or under the floor, turn up to the point of use, and directly connect the point of use; The other is the common pipeline laid in the interlayer, which is connected to the point of use through the functional column or partition wall.
Pay attention to the power supply design of high-power equipment such as sterilization cabinet (especially electric heating equipment); Stabilized voltage power supply and UPS shall be considered for precision instruments; Consider the separate grounding design of some precision instruments; Consider reasonable network, monitoring and socket design.

1.4 Fire protection and safety design
The layout of the laboratory should consider that the fire evacuation corridor meets the specification requirements.
The water fire-fighting system shall be set up according to the requirements of the specification, and the pre action sprinkler system can be considered for spraying, so as to avoid the loss of equipment caused by accidental spraying.
Control the total amount of reagent storage, and select the reagent storage cabinet with ventilation.
If there is hydrogenation reaction, it should be set up separately, the area should be controlled to the minimum, and it should be arranged at the end of the building. It should be designed according to the explosion-proof area, and sufficient pressure relief area and door bucket should be considered.
The experimental area is equipped with emergency shower and eye washer and other personal protection safety measures.
Articles and personnel in contact with active bacteria should consider sterilization measures and do a good job in biosafety protection.
