Laboratory furniture in the pursuit of the experimental environment comfortable and safe at the same time, should also meet the functionality, fixation, corrosion resistance, installation and layout flexibility and other requirements. In the construction of the laboratory, must pay attention to the design and selection of laboratory furniture, which requires a high level of structural and material requirements.
Laboratory furniture configuration is mainly considered: acid and alkali resistance, corrosion resistance, high temperature resistance, good load-bearing, easy to clean and other factors.
Laboratory furniture category mainly includes: test benches, rooftops, fume hoods, biological safety cabinets,, utensil cabinets, cylinder cabinets, safety cabinets,, fume hoods, reagent racks, workstations and so on.
Laboratory furniture category I: laboratory bench.
1, according to the structural form of classification.
Divided into fixed and combined two kinds.
2, according to the material classification.
Now the commonly used materials are steel and wood structure and all-steel structure.
3, categorized by the purpose of the experiment.
It has chemical test bench, instrument test bench, rooftop, washing test bench and so on, there are many kinds.
4, desktop.
Now commonly used desktop materials are as follows:
Physical-chemical board: it is screened high-quality multi-layer sandwich paper, immersed in special phenol solution, molded by high-pressure thermosetting action, and the surface of a special corrosion-resistant treatment.
TRESPA: Composition of 70% wood fiber, 30% melamine resin, using technology, melamine pasted on the surface layer, high temperature and high pressure molding.
Laboratory furniture category 2: laboratory cabinets.
1, drug cabinet.
To solid chemicals and standard solutions, the two must be placed in categories, not mixed together.
2, specialized cabinets.
Sample cabinet: used to place a variety of experimental samples of the sample cabinet, there should be separated, can be labeled and other partitions, in order to facilitate the storage of samples and samples to find.
Drug storage room: used to store volatile drugs, such as hydrochloric acid, nitric acid, perchloric acid, organic reagents and other liquid reagents. It is usually made of wood or steel and can store reagents of different specifications.
Dangerous Goods Storage Tube Cabinet: It is suitable for simple and short-term storage of dangerous goods, made of stainless steel, or made of refractory bricks.
(4) glassware drying and storage cabinet: washed utensils placed on the bracket, the bracket is fixed to the cabinet with a guide rail, easy access to glassware, each layer of the bracket can be adjusted according to the size of the position of the utensils, the bracket is well ventilated, easy to clean and dry.
