The furniture for modern analysis laboratory construction should not only have excellent functions, but also have a clean and bright appearance and color to improve the indoor environment and reflect the characteristics of the times. Reflect the laboratory's analytical testing level and analytical testing capabilities. Laboratory furniture design flexibility and serial production are one of the components in the laboratory design and construction, and one of the basic conditions of the laboratory.

Detailed explanation of laboratory furniture configuration for modern analysis laboratory construction (part 1)

In order to meet the needs of laboratories with different experimental contents, laboratory furniture should meet the functionality, robustness, corrosion resistance, and flexibility of installation and layout while pursuing a comfortable and safe experimental environment. There are a lot of laboratory furniture, but they are mainly classified into several categories, such as laboratory benches, laboratory cabinets and fume hoods. Laboratory furniture is different from household furniture. Its use is often in contact with water, electricity, gas, chemical substances, and instruments and equipment. Therefore, higher requirements are placed on the structure and material of the furniture, and the laboratory must be paid attention to in the design and construction of the laboratory. Furniture design and selection. The fume hood used in the laboratory has been introduced above, and the laboratory bench and the laboratory cabinet are now explained.

According to the structure, the experiment table can be divided into a fixed experiment table and a combined experiment table. There are many forms of fixed test benches, and they are still widely used in China. Common countertops and brick supports with reinforced concrete structure, wooden utensil cabinets under the counter, white ceramic tiles, terrazzo, marble or natural granite, etc., are used for this kind of laboratory benches, which are durable, high temperature resistant, and stable. They are often used Sky platform, high temperature stove and photometric instrument platform, etc. The modular test bench is divided into several independent parts depending on its own structure, which are made separately and then combined together. It is mainly composed of several unit test benches, pipeline racks, reagent racks, pool benches and other parts. According to the experiment The rooms need to be assembled, and the characteristics of the laboratory can be flexibly arranged, which is convenient for transportation and serialized production.

According to the material, the test bench can be divided into wood structure, steel structure, reinforced concrete structure and mixed structure. Wood structure is a commonly used form at home and abroad. It is lighter in weight, more flexible, and can be made into various unit combinations. The disadvantage is that it consumes more wood. The steel structure is composed of steel brackets, utensil cabinets, countertops, reagent racks and other components. The steel brackets are made of thin-walled steel. The feet of the foot brackets are equipped with fine-tuning screws. There is pipe space between the steel brackets. The utensil cabinets are wooden structures. It can be flexibly hung on a steel bracket. Although this material has anti-corrosion coating on its surface, it is unavoidable to be rusted. It is generally used in instrument analysis rooms. Reinforced concrete structure test bench includes reinforced concrete structure table and support (or brick support) and utensil cabinet under the table. Its disadvantage is that it is large in quality and lacks flexibility. The mixed structure uses a steel frame, a reinforced concrete countertop and a movable wooden utensil cabinet, which may also be made into a unit combination type, which is lighter in weight and is more advantageous than a reinforced concrete experimental bench in terms of flexibility.

In addition, the laboratory benches mainly include chemical laboratory benches, instrument laboratory benches, overhead platforms, washing benches, etc. according to the purpose of laboratory construction. Depending on the layout of the laboratory, it is located in the middle of the laboratory and is called an island-style experimental platform; one end of the experimental platform against the wall becomes a peninsula-style experimental platform; if one long side of the experimental platform is against the wall, it becomes a side experimental platform. The corresponding reagent racks, washing stations, and utensil cabinets are also different.

Because of the different nature of laboratory design and construction, the required length of the chemical laboratory bench varies greatly, but usually 1200mm per person (minimum should not be less than 1000mm) is considered, while the organic chemistry laboratory bench can be 1400~1600mm. The height of the chemical laboratory bench is generally 850mm. If the proportion of male laboratory personnel is higher, 900mm can be considered. For some special experimental work, it can also be made as low as about 750mm. The net width of each side of the experimental table should generally be 750mm, and the minimum should not be less than 600mm. The width of the medicine rack on the table can be 200-300mm. It is recommended that the width of the double-sided test bench is 150mm, and the single-sided test bench is 650-850mm.
