Laboratory furniture, general laboratory home has: laboratory, fume hood, central station, reagent rack, utensil cabinet, medicine cabinet, etc. If you want to plan a laboratory, called n to do experimental furniture dealers do n Quote, then how can I choose one of the most desirable ones? For a lab, how to distinguish its quality is good or not? First look at the qualifications of the dealer, look at the laboratory cases it has done, you can Let the dealers take us to visit the labs they have done. If this is done, it means that the dealer is very sincere to the customers, and then listen to how they evaluate the dealers, what they say. It will be more useful than the dealers, and take this opportunity to observe whether the appearance of their laboratory furniture is beautiful and the structure is strong. Another point is that if the manufacturer of the laboratory furniture is found, it is better because it is the manufacturer. In case they are cheaper than dealers, they can go to their factory to see their entire process. If you contact a certain laboratory furniture, they will first give you a floor plan and then make a preliminary offer. How do we distinguish the quality of a test bench only if there is a list of quotes? If you There is a very general list of very rough mines on hand. It is estimated that this experimental furniture manufacturer is not guilty. Why do you say this? Because the very coarse list contains a lot of water, it is a steel-wood experiment platform. The same material, different configurations, the price can be half the difference, but on the surface you may look exactly the same, especially the newly made furniture, almost exactly the same. The raw materials required for a steel-wood test bench are: countertops, wood panels (melamine panels), steel frames, handles, rails, hinges, plugs, adjustment feet, etc. Can these things be found on your list? There are brands, places of origin, Are the materials and specifications the most detailed description? A table with the same specifications (25 standard boards, 12.7 solid core physical and chemical boards, 16 epoxy resin boards) can be a lot different, but their performance is also very different. The specific price can be checked online: 25mm standard board: It is a surface layer made of surface paper, colored paper and kraft paper. The inside is particle board (melamine board). It is not resistant to high temperature, does not prevent strong acid and alkali, can not be repaired after scratching on the surface, and is easy to warp. If he uses a standard countertop in your chemistry lab, then he just wants to attract your attention with low prices, which is very irresponsible. 12.7mm solid core physicochemical board: It is a layer made of multi-layered cowhide paper, which is made of particle board (melamine board), which can protect different degrees of strong acid and alkali, but the desktop will leave different degrees of defects. Not resistant to high temperatures (about 80 degrees), easy to deform, unrepairable features, in the mainstream stage of the laboratory countertops before 2008, is now slowly being phased out because it has defects. 16mm epoxy resin board: the full name is epoxy vinyl ester resin board, which is made by mixing epoxy resin, quartz sand, curing agent and pigment, and is baked at high temperature. It is resistant to 350 degrees high temperature and has an instantaneous temperature of 600 degrees. The problem is to prevent strong acid and alkali, and it is not easy to be denatured. After the surface is scratched, a 600-mesh sandpaper is used, and then the oil is rubbed. Just like the new one, the epoxy resin board has become the mainstream of the laboratory countertop. Some manufacturers will buy their own epoxy resin plates to cut their own processing, the price will be cheaper than it, but the nature of the countertop is basically unchanged. 25mm standard board price 180 units / square 12.7mm solid core physics and chemistry board Shanghai VIA Asia 300 units / square 12.7mm solid core physics and chemistry board Wuhu Weishengya 180 units / square 12.7mm solid core physicochemical board Jiangsu Weishengya 170 units / square 16mm epoxy resin board 420 units / square Wood board: The melamine board industry is divided into many types. The brand, thickness and color are different. The good tripoly board must be the national E1 board. The formaldehyde is not exceeded. The cut is visible inside, but it is powdery. The price of a good tripoly plate and the worst tripoly plate can differ by more than half. Oh, the edge banding machine used to seal the edge of the tripoly plate is better. This kind of edge banding is not easy to fall off, it is not easy to enter the water, and the polytriene plate enters the water. It’s basically over. Ordinary square board is about 50 units / piece Steel frame: The steel frame of the steel frame depends on the place of production, whether it is Maanshan Iron and Steel or Anshan Iron and Steel. If the steel is not the steel, it is estimated that it is not very reliable. Or it is not necessary to use iron instead. The steel should see the thickness. 1.2 of 1.6 and 1.2 of 1.8, of course, the thickness is relatively firm. The surface is polished, acid washed, phosphatized and epoxy resin sprayed, which can effectively prevent acid and alkali, rust and epoxy. Epoxy resin spray is also thick, so be careful. Handle: It can be a common alloy handle of a few cents, or it can be a tens of dollars and a meter is a plastic one-shaped handle, or it can be a higher-priced aluminum alloy spray handle. Hinge, guide rail: The brand of these accessories is very important, which determines its price and quality, you can go online to check. Laboratory accessories are also important, such as sinks, faucets, drip racks, eye washers, etc., which depends on the brand. In this way, the price difference between a seemingly identical test bench is generally very normal. Of course, we are not saying that the higher the price, the better. For example, some physical laboratories do not need to prevent acid and alkali, so some things are also There is no need, according to their actual needs, there will be no mistakes, but if the demand does not meet the requirements, this is a very serious matter, and the consequences will be very serious.
