The first part of the PCR laboratory plan is graphic design. Party A (user) first takes out the most fundamental functional requirements and distribution plans. Party B (Design Institute), Party C (Laboratory Planning and Design Professional Company) and Party A participate in the experiment. The room construction design team will discuss together and the three parties will confirm the latter to enter the second procedure. Because the traditional laboratory building design is based on national building standards, it is mainly based on exterior and indoor structures. It is not based on laboratory functions, and the architectural design and functional design are out of touch. Our company has many lessons in this regard.
The second part is a single function, single structure design, should be determined item by item, piece by piece, layer by layer, from the whole building, layered, divided rooms, sub-piece design, comprehensive subdivision confirmation;
The third part, after all confirmation, invites the senior leaders of the user to participate in the laboratory construction demonstration meeting, and makes decisions on the spot; Party A invites Party B and Party C's project supervision to strictly supervise the installation and standard implementation of the construction process to track the laboratory construction project. Successful completion; construction laboratory planning and design and product tendering are divided into two parts.
1. Single structure function design system
Laboratory specialization uses different laboratory-specific basic equipments. The series products are divided into five parts: A, laboratory part; B, instrument part; C, functional cabinet part; D, instrument and equipment part; E, output system part A, the experimental bench section
1. Classification of experimental benches: 1 Experimental benches are divided into: physical test benches (mainly used for electronics, electrical and physical experiments), chemical test benches (mainly used for organic and inorganic chemical experiments), and biological test benches. (Mainly used for purifying sterility experiments, such as simple dissection table, stainless steel console, etc.); 2 According to the structure and style, it is divided into: MM (consisting of steel support frame, base box, table top, reagent rack, connecting parts and accessories) ) MR (base box, table top, reagent rack, connecting parts, accessories). 3 According to the use, it can be divided into: central experimental bench, side bench test bench, washing test bench, reagent rack, base box and experimental bench.
2, the classification of the basic box: The basic box can be divided into: steel wooden base box, aluminum wooden base box, all wooden base box. According to the production process, it is divided into: steel European base box (that is, door panel and side panel connection), steel American base box (that is, door panel is embedded in the base box). According to the style, it can be divided into: movable base box and floor type. Base box, hanging base box. Among them, the movable base box and the hanging base box are used for the MM model. Floor-standing base box for MR models. The steel wooden base box is newly developed by our company. The side panels and door panels are made of steel. Others such as laminate, top plate, drawer bottom plate and maintenance plate are made of wooden material. It is safe, fireproof, cost-effective, and glassware. It is not easy to break when placed. All wood is not suitable for making hanging base boxes and washing tables.
3, the classification of the countertops In the entire laboratory basic equipment sales, the countertops accounted for 1/3 of the total offer, the role of the countertop can be seen. 1 According to the function of the test bench, it can be divided into: Chemical test bench: anti-strong acid, strong alkali, high temperature resistance; 98% concentrated sulfuric acid; surface material is phenolic resin board physical test bench: anti-static, temperature-resistant, anti-slip, Stable and strong; resistant to 28% sulfuric acid, the surface material is fireproof board biological test bench: waterproof, prevent bacterial density; surface material is stainless steel plate. 2 According to the table top material can be divided into a veneer and a solid core board.
Second, water supply and drainage design system
The laboratory decoration water supply and drainage design system is mainly for the early laboratory building design services. Provide the upper and lower water points of the experimental platform for the architectural design institute. The nozzle is divided into a jet nozzle and a slow nozzle, and the single nozzle (MBs-016) is a rapid nozzle. Generally with PP sink (MBc-032). Double nozzle (MBs-02) is a slow-flow nozzle, generally with PP sink (MBc-029) specifications. By default we generally configure the customer with a double nozzle. The triple faucet (MBc-01) is an emergency two faucets. Generally with PP sink (MBc-029). Large sink (MBc-031), cupboard for fume hood (MBc-028).
Third, the electronic control system
Laboratory power mainly includes two parts: lighting and power. Power supply is mainly used for power supply of various types of equipment and equipment, elevators, air conditioners, etc. The laboratory power supply system is also one of the most basic conditions in the laboratory. Power sockets are: 10A, 13A, 16A, 20A; leakage protection switch, overload protection switch, etc. The power socket should be away from the nozzles of the water basin and gas, hydrogen, etc., and does not affect the placement and operation position of the instrument. The trunking is mainly used for multi-purpose steel trunking (mainly used on reagent racks) and PVC trunking with Spanish sockets (mainly used for side and central countertops).
Fourth, special gas distribution system
The laboratory gas mainly includes non-combustible gas (nitrogen, carbon dioxide), inert gas (argon gas, helium gas, etc.), flammable gas (hydrogen, carbon monoxide); highly toxic gas (fluorine gas, chlorine gas); combustion gas (oxygen) composition . Except for non-combustible gases and inert gases, other gases shall not be used in the laboratory. It can be connected to each laboratory through the gas pipe. Generally, the gas phase chamber is equipped with helium (He) and nitrogen (N2).
The GC/MS is equipped with nitrogen, hydrogen and oxygen. The connecting pipe fittings on the hydrogen pipeline must be connected and welded. It is strictly forbidden to leak. All pipelines must be airtight after installation and must be degreased before use. Due to the small size of the pipe, the pipe spacing is small, and the installation process can be adjusted according to the site conditions to ensure that the spacing is not less than 45mm. When the gas cylinder is bottled, the flammable and explosive gas and the inert gas are in the same cabinet, and the two flammable gases are sealed in the same bottle.
V. Laboratory decoration harmful gas output system
There are often many sources of chemical contamination that are not conducive to human health in the laboratory, especially harmful gases. It is very important to eliminate them. At the same time, however, energy is often consumed in large quantities, and the requirements for laboratory ventilation control systems are increasing, from early CV (constant air volume), 2-State (bistable), VAV (variable air volume) systems, To the latest adaptive control system – both safe and energy efficient.
In short, the latest concept of the laboratory is to treat the entire laboratory as a smoke exhaust cabinet. How to effectively control various intake and exhaust, it is essential to achieve safe and economical effects. Commonly used exhaust equipment in the laboratory are: fume hood, atomic absorption hood, universal exhaust hood, ceiling hood, overhead hood and so on. The fume hood is the most common. The fume hood is a ventilating device that safely handles hazardous, toxic gases or vapours. It is used to capture, seal and transfer contaminants and harmful chemical gases to prevent escape into the laboratory, thus keeping them away from contaminants in the work area. The operator, to minimize the inhalation contact.
The airflow in the fume hood sucks the air in the laboratory into the fume hood through the exhaust fan, dilutes the polluted gas in the fume hood and discharges it to the outside through the exhaust system, which can achieve low concentration diffusion; the universal hood is The first choice for local ventilation: simple installation, flexible positioning, good ventilation performance, can effectively protect the personal safety of laboratory staff; Atomic absorption hood is mainly suitable for all kinds of large-scale precision instruments, requires positioning and installation, and has set ventilation performance parameters. It is also one of the factors that must be considered in the overall laboratory planning; the exhaust hood is mainly used in chemical laboratories, and it is one of the essential equipments to solve the overall ventilation requirements of such laboratories.
