How to choose laboratory furniture such as laboratory bench and fume hood from the perspective of material?
According to the functions of the experimental table and the fume hood, it can be divided into: physical experimental table and ventilated counter top: antistatic, temperature resistant, anti-sliding, stable and strong; the surface material is fireproof board; 28% sulfuric acid resistant. Biological experiment bench, ventilated countertop: waterproof, prevent strong bacteria density; surface material is stainless steel plate. Chemical laboratory bench, ventilated countertop: anti-strong acid, strong alkali, high temperature resistance; surface material is phenolic resin board; 98% concentrated sulfuric acid. According to the material of the countertop, it can be divided into veneer board and solid core board: solid core board is divided into: epoxy resin board, marble, ceramic, etc. Epoxy resin is a polymer material that is resistant to high temperatures and has excellent chemical resistance, which can be repaired and restored. Marble is generally used in high-temperature platforms, rooftops, etc., which is resistant to high temperatures, but is easily damaged during transportation. Ceramics are relatively expensive and are used less in China. The test bench is divided into materials, including a steel structure test bench, a wooden structure test bench, and a steel-wood structure test bench. Each material has its own advantages and disadvantages.
1. Wooden bench
It is mainly made of melamine board, and is supplemented with auxiliary materials such as plywood and medium-density fiberboard. According to the climate differences in different regions in the country, the boards of different origins are reasonably selected to meet the requirements of laboratory use.
Features: reasonable price; wide variety of wood, easy to process, easy to form, novel and unique; easy installation and disassembly, convenient after-sales service; excellent acid and alkali resistance.
2. Steel-wood structure test bench
Steel-wood structure test bench includes two structures: one is H-frame type and the other is C-frame type. H-type dignified and generous, good load-bearing performance. The C-type structure is simple, flexible and can be combined at will.
Features: Use 40 * 60/30 * 30 square steel, the surface is phosphated, pickled, and then treated with epoxy powder baking paint, no protruding paint block, bright and beautiful, strong resistance to strong acids and alkalis; can adjust the overall level, Equipped with primary shock absorption function, the load can reach more than 150kg; the countertop can use laboratory special countertops such as epoxy resin and Trespa. C-frame can be used with hanging cabinet and push cabinet structure, which is easy to install and remove, which is conducive to laboratory cleaning. The steel frame of H-frame makes the test bench bear more than 500KG, which meets the requirements of large precision instruments.
3.All-steel structure test bench
The all-steel laboratory operation platform has the advantages of good load-bearing performance, long service life, and excellent cost performance. The development of the laboratory is inevitable. The all-steel series floor-standing experimental operation platform adopts computer-aided design and numerical control manufacturing as a whole. It is a unit body structure with high manufacturing accuracy, which can be easily assembled with any combination, has strong adaptability, high cost performance, and is durable.
How to choose basic laboratory furniture? It is necessary to determine the material according to the nature of your experiment, and the temperature and humidity environment of your area, otherwise the aging rate of laboratory furniture will be accelerated. Choosing good laboratory furniture is actually a matter of learning.
