Classification and analysis of test benches

I. Classification by structure.

There are three types of experimental platforms: experimental central table, experimental side table, experimental corner table.

Second, according to the experimental use of classification.

There are mainly a wide variety of chemical laboratory bench, instrument laboratory bench, rooftop platform, washing table, corner table and so on. According to the laboratory layout, the experimental bench is located in the middle of the laboratory, known as the island type experimental bench; experimental bench one end of the wall known as the peninsula type experimental bench; if the long side of the experimental bench against the wall known as the side of the experimental bench. The corresponding reagent racks, washing table and container cabinets are also different. Some also divide the laboratory bench into single-sided laboratory bench and double-sided laboratory bench, the latter actually refers to the island type laboratory bench and peninsula type laboratory bench.

Third, according to the material classification.

Wooden structure:This is a commonly used form at home and abroad, light in quality, flexible, can be made into a variety of unit combinations, the disadvantage is the high consumption of wood.

Steel structure:The structure consists of steel bracket, cabinet, countertop, foot and other components. The steel bracket is made of thin-walled steel, the foot bracket has ground screws at the bottom, and there is piping space between the steel brackets. The cabinet is a wooden component that can be flexibly hung on the steel brackets. Although the material has an anti-corrosive coating on the exterior, it will inevitably rust and is generally used in instrumental analysis rooms. Advantages of steel laboratory furniture: sturdy, beautiful, can be used for more than 10 years to maintain no deformation, strong acid, strong alkali, is the direction of development of laboratory furniture.

All-steel structure: composed of steel bracket, all-steel cabinet, table top, floor feet and other components. The steel bracket is made of thin-walled steel, and there are ground screws at the bottom of the foot bracket, and there is piping space between the steel brackets. The steel cabinet is a wooden component that can be flexibly hung on the steel brackets. Although the material has an anti-corrosive coating on the exterior, it will inevitably rust and is generally used in instrumental analysis rooms.

In the entire laboratory infrastructure equipment sales, countertops account for 1/3 of the total offer, the role of countertops can be seen.

Fourth, according to the functional classification.

Chemical test bench top: strong acid, alkali, high temperature resistance; 98% concentrated sulfuric acid; such as solid core physical and chemical board.

Physical test bench top: anti-static, temperature resistance, slip resistance, strong stability; 28% sulfuric acid resistance, surface materials for fire board.

Biological test bench top: waterproof, prevent bacteria density is strong; surface material for stainless steel plate.

Fifth, according to the countertop material classification.

Can be divided into physical and chemical board, epoxy resin board, marble board and ceramic board.

Physicochemical board (VIA) can not directly contact the light flame, 65% nitric acid, chromic acid, hydrofluoric acid has a slight defect, 98% sulfuric acid has a defect;

Epoxy is a high temperature (380°C) resistant polymer material with excellent chemical resistance that can be repaired and restored;

Marble is generally used for high-temperature platforms and overhead platforms, etc. It is resistant to high temperatures, but is easily damaged during transport;

Ceramic is expensive and less used in China. Its high temperature and corrosion resistance.
