The overall planning and design of a laboratory is a complex system engineering that involves numerous disciplines, and requires proficiency in both laboratory usage knowledge and architectural knowledge as the technical foundation. Whether it is new construction, expansion, or upgrading and renovating, it is not just about selecting reasonable laboratory furniture and advanced equipment. It is also necessary to comprehensively consider the overall planning, reasonable layout, and graphic design of the laboratory, as well as the infrastructure and basic conditions such as strong and weak electricity, water supply and drainage, gas supply, ventilation, air conditioning, air purification, safety measures, and environmental protection.

9 major concepts for laboratory planning and design

Based on the planning and design philosophy of "safety, environmental protection, intelligence, practicality, durability, aesthetics, and economy", we always adhere to the principle of "people-oriented" in the design process, designing safe overall designs, functional products, and beautiful and practical furniture, which are the prerequisites for the success of high standard laboratories. Facing different customers and laboratories, accurately conveying customer information to the design department, the design department conducts reasonable design, and provides customers with a new laboratory design solution that is "economical, comfortable, practical, efficient, safe, and intelligent".

Safety: When conducting experimental work, safety must be ensured, especially when conducting chemical experiments. Toxic, harmful, and odorous exhaust gases must be effectively discharged to ensure the physical and mental health of experimental personnel.

Efficient: Improving experimental efficiency is necessary to accelerate the experimental process, and appropriate experimental equipment must be configured according to different experimental topics and their technological requirements.

Comfort: Bright and friendly colors: ergonomically designed exterior dimensions; Convenient and practical functions, as well as environmentally friendly material selection, ensure the comfortable work of researchers.

Four principles of laboratory planning, decoration and design

The experiment is not dangerous; Work without fatigue; improve air circulation Lighting without dark areas.

Laboratory planning and design are mainly divided into six system aspects

Aseptic laboratory planning and decorationExplain the graphic planning and design system

(1) Laboratory Design Specification (2) Laboratory Space Scale (3) Laboratory Functional Layout (4) Laboratory Interior Layout (5) Laboratory Furniture

The laboratory spatial scale, also known as the laboratory modulus, generally refers to the dimensions of the laboratory's opening, depth, floor height, and corridors. It depends on the scope of activities of the researchers and the requirements for the layout of experimental equipment and instruments.

The laboratory layout follows the requirements of the laboratory building design specifications and building fire protection design specifications, separating the office area from the experimental area and setting up an access control system between the two. Coordinate between the main laboratory and auxiliary functions, and distribute them reasonably according to the laboratory functional process. Consider separating the flow of people and goods to ensure no cross contamination of samples and the accuracy of experimental data. An emergency shower device is designed in the experimental area to reduce the danger to experimental operators.

We mainly consider the following factors in the specific graphic design

Evacuation, evacuation, escape, smooth, unobstructed, safe passage; Generally, laboratory doors should open inward, but if there is a risk of explosion in a room, the door should open outward, and pressure glass is preferred as the door material.

The perfect coordination and combination of ergonomics (front, back, left, right workspace) and the operational space range of technology workers reflects a scientific and humanized planning and design.

When doing graphic design, the first factor to consider is "safety". Laboratories are places prone to explosions, fires, toxic gas leaks, and other hazards.

When we are doing graphic design, we should try our best to maintain smooth ventilation and escape routes in the laboratory.

Standard for channel division between experimental benches (channel spacing indicated by L)

L> At 500mm, one side can be operated by standing people;

L> At 800mm, one side can be operated by sitting people;

L> At 1200m, people can sit on one side, stand on the other side, and no one is allowed to pass in between

L> At 1500 hours, people can sit on both sides and pass through the middle

At 1800mm, people can sit on both sides and pass through the instrument in the middle

The sky platform and instrument table should not be too close, and a height of 400mm is recommended. In order to facilitate evacuation in case of work hazards, all corridors between the experimental benches should lead to the corridor. Additionally, the floor height of the laboratory building should be between 3.7 meters and 4.0 meters, and the net height should be between 2.7 meters and 2.8 meters. For laboratories with special requirements such as cleanliness, pressure gradient, and constant temperature and humidity, the net height should be between 2.5 meters and 2.7 meters (excluding suspended ceilings); The clear width of the laboratory corridor should be between 2.5 meters and 3.0 meters. The ideal width for a double door in a regular laboratory is 1.1-1.5 meters (asymmetric double door), while the ideal width for a single door is 0.8-0.9 meters.

Professional learning material function. Laboratories are usually classified according to physics, inorganic chemistry, organic synthesis chemistry, and biology. According to the different contents, purposes, and scales of the laboratory, each has its own characteristics. For example, basic teaching laboratories, classified by subject and major, are mostly relatively simple teaching experiments with lower requirements for water, electricity, gas, and air. Research institutions have high requirements for laboratory ventilation, water supply and drainage, electrical control, and cleanliness, but the basic principles of laboratory design are common. Taking organic chemistry as an example, it mainly consists of chemical basic laboratory, instrument analysis laboratory, clean laboratory, electronic computer laboratory, research room, auxiliary laboratory, service supply room, etc.

Single structural functional design system

Different majors adopt different laboratory basic supporting equipment, and the series of products are divided into five main parts

A、 Experimental bench section; B、 Instrument platform section; C、 Functional cabinet section; D、 Instrument and equipment section; E、 Output system part;

Water supply and drainage design system

The water supply and drainage design system mainly serves the preliminary laboratory building design. Provide experimental platform water points for the architectural design institute. The water nozzle is divided into a rapid flow nozzle and a slow flow nozzle, and the single connected water nozzle (MBs-016) is a rapid flow nozzle. Usually paired with PP sink (MBc-032). The dual water spout (MBs-02) is a slow flow spout, usually paired with a PP sink (MBc-029). By default, we usually provide customers with dual water nozzles. The triple water nozzle (MBc-01) is a quick and slow water nozzle. Usually paired with PP sink (MBc-029). Large sink (MBc-031), cup slot for fume hood (MBc-028).

electric control system

The electricity used in the laboratory mainly includes two parts: lighting electricity and power electricity. Power electricity is mainly used for supplying electricity to various instruments and equipment, elevators, air conditioning, etc. The laboratory power supply system is also one of the basic conditions for the laboratory. Power sockets include 10A, 13A, 16A, 20A: leakage protection switch, overload protection switch, etc. The power socket should be kept away from the water basin and nozzles for gas, hydrogen, etc., and should not affect the placement and operation position of the experimental equipment. The main use of cable trays is multifunctional cable trays (mainly used on reagent racks) and PVC cable trays with Spanish sockets (mainly used on edge and central countertops).

Special gas distribution system (gas path)

Laboratory gases mainly include non combustible gases (nitrogen, carbon dioxide), inert gases (argon, helium, etc.), and flammable gases (hydrogen, carbon monoxide); Highly toxic gases (fluorine gas, chlorine gas); Composition of combustion supporting gas (oxygen). Except for non combustible gases and inert gases, no other gases are allowed to enter the laboratory. It can be connected to various laboratories through gas pipelines. The general gas phase chamber is equipped with helium (He) and nitrogen (N2). The gas chromatography-mass spectrometry room is equipped with nitrogen, hydrogen, and oxygen. The connecting fittings on the oxygen pipeline must be welded after connection, and there is no possibility of leakage. All pipelines must undergo air tightness tests after installation and be degreased before use. Due to the small size of the pipeline and the small spacing between pipes, the installation process can be adjusted according to the site conditions to ensure that the spacing is not less than 45mm. When filling gas cylinders, flammable and explosive gases should be stored in the same cabinet as inert gases to prevent the two flammable gases from being stored in the same cabinet.

Harmful gas output system (exhaust gas treatment)

There are often many sources of chemical pollutants in the laboratory that are harmful to human health, especially harmful gases, and it is very important to eliminate them. However, at the same time, energy is often consumed in large quantities, so the requirements for laboratory ventilation control systems are high. The new concept of the laboratory is to treat the entire laboratory as a smoke exhaust cabinet. It is crucial to effectively control various intake and exhaust gases to achieve both safety and economy. The commonly used exhaust equipment in laboratories mainly includes fume hoods, atomic absorption hoods, universal exhaust hoods, ceiling mounted exhaust hoods, and countertop exhaust hoods.
