According to the function of the test bench and the ventilator, it can be divided into:
Physical test bench and ventilation cabinet countertop: anti-static, temperature-resistant, anti-skid, strong stability; surface material is fireproof board; 28百分比 sulfuric acid resistance.
Biological test bench and ventilation cabinet counter: waterproof, strong bacterial density; surface material is stainless steel plate.
Chemical test bench, ventilation cabinet counter: strong acid, alkali, high temperature resistance; surface material is phenolic resin board; resistant to 98百分比 concentrated sulfuric acid.
According to the material of the mesa, it can be divided into paste panel and solid core board.
Solid core board is divided into: epoxy resin board, marble, ceramics and so on.
Epoxy resin is a high molecular material with high temperature resistance and excellent chemical corrosion resistance. It can be repaired and restored.

Marble is generally used for high temperature platforms, skyscrapers, etc. It can resist high temperature, but it is easy to be damaged during transportation.
Ceramics are expensive and seldom used in China.

There are steel structure test-bed, wood structure test-bed and Steel-wood structure test-bed. Each material has its own advantages and disadvantages.
1. Wooden Structure Test Bench
Mainly melamine board as the main material, combined with splint, medium density fiberboard and other auxiliary materials, according to the climate differences of different regions in China, reasonable selection of plates from different origins, so as to meet the requirements of laboratory use.
Features: Proper price; Various kinds of wood, easy processing, easy forming, novel and unique; easy installation and disassembly, easy after-sales service; excellent acid and alkali resistance.
2. Steel and Wood Structure Test Bench
There are two kinds of structures in the steel-wood structure test-bed: H-frame type and C-frame type. H-type is dignified and generous, with good load-bearing performance. The C-type structure is simple, flexible and changeable, and can be combined at will.
Features: 40*60/30*30 square steel is selected, the surface is phosphated and pickled, and then treated by epoxy powder baking paint. No prominent paint block, bright and bright, strong acid and alkali resistance is prominent; the overall level can be adjusted, with primary shock absorption function, the load-bearing capacity can reach more than 150 kg; the table can be selected epoxy resin, Thousand Thousand Thousand Thousand Plates and other laboratory dedicated countertops. C-frame can choose suspension cabinet and push cabinet structure, which is convenient for installation and disassembly and for laboratory cleaning. The steel structure of H-frame makes the load-bearing capacity of the test bench reach more than 500 KG, which meets the requirements of large precision instruments.
3. All-steel structure test-bed
All-steel laboratory operating platform has the advantages of good load-bearing performance, long service life and good cost performance. In recent years, it has been highly praised by domestic and foreign laboratory users. It has the development trend of gradually replacing wooden laboratory operating platform, which is the trend of future domestic laboratory development.
All-steel series of floor-type experimental operating table, the overall use of computer-aided design, numerical control manufacturing, as a unit structure, manufacturing accuracy, can be easily assembled, adaptable, cost-effective, safe and durable.
How to choose basic laboratory furniture? It is necessary to determine the material according to the nature of your experiment, and also according to the temperature and humidity environment of your area, otherwise it will accelerate the aging speed of laboratory furniture. Choosing good laboratory furniture is also a matter of learning.
