How to arrange an analysis laboratory and purchase lab benches?

There are already topic posts on the forum discussing the issues related to laboratory construction; the original poster can search for them. \"Collection of Laboratory Workbenches (5 pieces)\” http://bbs.hcbbs.com/viewthread.php?tid=403972&highlight=%2B%B2%D4%BA%A3%D2%BB%C1%A3%C9%B0

You can build one that is stable; the usual height is 80 cm, while the width depends on the specific instruments used. For analytical instruments, the width is generally around 80 cm, whereas for chemical testing it’s usually around 60 cm. You can use bricks or wood for construction, but keep in mind that there should be a 50 cm gap behind the workbench where analytical instruments are placed, to facilitate future maintenance of those instruments

You can contact the manufacturers of the production and testing equipment directly; they can customize or assist with the design as required. Two such manufacturers are Jiangsu Pail and Wuxi Pruida.

A simple analysis of the layout of a laboratory, for reference only: Laboratory spaces should be arranged according to their functional areas. Rooms for staff to live and rest should be separated from the laboratory areas ； The instrumental analysis laboratory should be separated from the chemical handling area ； Instruments of different types or operating principles should be kept separate in the instrumental analysis laboratory; medium-sized analytical instruments ideally should have their own dedicated testing rooms ； Due to the high requirements regarding the operating environment and conditions, large precision instruments should have dedicated experimental areas. These areas are arranged in a modular (suite) layout, with all the sample preprocessing procedures required as well as the auxiliary and supporting facilities necessary for instrument operation located specifically within those areas. The temperature, humidity, and cleanliness in this experimental area must meet the requirements of the main equipment as well as the supporting facilities. 　　 Large precision instruments have a large size and weight, requiring vibration prevention and isolation; some of these instruments also need a separate foundation and grounding wire, and should be placed in a laboratory on the ground floor. A single-layer foundation provides solid support, has strong load-bearing capacity, offers good vibration resistance, and also facilitates the transportation, installation, and fixation of instruments. If, for various reasons, large precision instruments cannot be placed in laboratories on the first floor, it is better to locate them on lower floors. In such cases, it is necessary to enhance the load-bearing capacity of the room’s floor; the typical load-bearing capacity of laboratory floors is 400 ksf/m^2 (1 kgf = 9.80665 N). The load-bearing capacity required for floors in laboratories that house large precision instruments is usually greater than 600 kds/m^2 (the actual required capacity depends on the specific instruments). During the design phase, it is also necessary to consider the passages through which large, precision instruments will be transported, the load-bearing capacity and dimensions of stairs, as well as the size of doors. Additionally, it is important to determine whether a dedicated base or space for mounting bolts is required at the installation site. 　　 Organic synthesis rooms and drug synthesis rooms that make extensive use of organic solvents and generate corrosive gases or toxic and harmful substances, as well as sample digestion rooms that use large amounts of acids and bases, should generally be located on the upper floors of the laboratory, downwind of the instrument analysis rooms. If it must be installed near an instrumental analysis laboratory, proper ventilation equipment is essential. 　　 Instrument analysis laboratories typically require a stable room temperature, small daily temperature variations, and appropriate lighting, with direct exposure to outdoor sunlight avoided, in order to ensure the stable operation of the instruments and facilitate experimental observations. Therefore, the layout of laboratories for instrumental analysis should also take into account the orientation of the rooms; for example, instruments such as electron microscopes should not be placed in rooms facing south. If the room cannot be kept away from outdoor sunlight, a sunshade should be installed outside the window or curtains should be used inside to block direct sunlight, thereby maintaining an appropriate level of illumination and stable room temperature. 　　 Analytical instrument laboratories should be located away from railways, roads with heavy traffic, factories or workshops that produce corrosive, toxic, or harmful substances or have sources of mechanical vibration, radio station towers and high-voltage power lines that generate strong electromagnetic radiation, as well as cement plants, power plants, coal storage areas, and other sites that produce dust. In addition to paying attention to the external environment, it is also necessary to consider the mutual influence among various analytical instruments.

It is recommended to first take a look at the \"Manual of Analytical Laboratory Equipment\" published by Chemical Industry Press to gain an understanding of laboratory design. Then find a laboratory renovation company with strong capabilities nearby to carry out the renovation. The \"Manual on Analytical Laboratory Equipment\" forum offers a download link: http://bbs.hcbbs.com/viewthread.php?tid=416581&highlight=%B7%D6%CE%F6%CA%B5%D1%E9%CA%D2%D7%B0%B1%B8%CA%D6%B2%E1

There are custom-made ones available outside; they arrive quickly when ordered, and the quality is good. Usually, companies also use them for testing benches

Thank you to all the friends above! If you have any questions in the future, feel free to ask everyone. :)

One can design one according to the size of the workshop laboratory. A testing bench is usually 600–800 mm wide and 800 mm high; it can be made of wood, or constructed from bricks with a cement finish and tiled surface. Below the testing bench, there should be a cabinet for storing chemicals, with double doors. It’s also possible to purchase ready-made testing benches, though their price isn’t too low; most of these benches are made of particle board with rubber sheets on top, and sellers can be found online.

It’s more practical to build it with bricks by oneself, but vibration prevention needs to be taken into account, as even a slight vibration in some instruments can cause errors in the data!

For more precise instruments, vibration prevention should be considered, such as electronic balances and other electronic devices, as vibration affects the data. The temperature and humidity of the environment, whether the exhaust ventilation is adequate, and also the corrosion resistance of the experimental bench need to be taken into consideration.
