What should you consider when purchasing an experimental bench?
What should you consider when purchasing an experimental bench? Before choosing a laboratory bench, you must be familiar with the purpose of the laboratory. Laboratories with different purposes have different requirements.
The chemical analysis laboratory stores many chemical reagents. It requires a central experimental bench with two sides in the center, and side benches, test benches, fume hoods, medicine cabinets, drying cabinets, etc. on both sides. In order to ensure the safety of experimental operators, a purification bench is also required according to demand. The experimental bench is required to be resistant to strong acids and alkalis.
The experimental table required in the physics laboratory must be wear-resistant and high-temperature resistant. The physics laboratory requires a higher load capacity of the experimental bench structure than the chemistry laboratory, so different structures should be selected according to different load capacity requirements.
The requirements for experimental furniture, especially experimental benches, in primary and secondary schools are very different from those of national scientific research laboratories. Therefore, you need to know which group of people it is used for before purchasing.
You also need to understand the scale of the laboratory, the area occupied by various devices, the size, configuration and function of the experimental bench, indoor passage space, lighting issues, and the interrelationships and operating procedures between other experiments or experimental benches. Then choose suitable experimental furniture according to your own budget.
Of course, the price of the experimental bench needs to be taken into consideration. During the purchase process, you should not be blindly greedy for cheap. A too cheap experimental bench will not only have a short service life, but also look frizzy. Although good experimental furniture is relatively expensive, it has a long service life. The prices of experimental benches made of different materials also vary greatly. The benchtops are also divided into solid boards, veneer panels, and imported epoxy resin benchtops. The prices are also different, so functions and costs must be considered comprehensively.
Also pay attention to the selected board, pay attention to whether the edge sealing of the laboratory furniture is firm, whether there is any odor, and whether it meets environmental protection requirements; veneer physical and chemical boards cannot be used for the countertop of the pool table, because the veneer physical and chemical boards are prone to bubbles, falling off or cracking when soaked in water for a long time;
Pay attention to the hardware accessories. Sometimes the hardware accessories are not selected well. Even if the materials used in the experimental bench are the best, it will affect the use experience and cause various inconveniences in future work.
