Do you know the classification of the test bench?

2020-03-05

The products of the laboratory bench have been comprehensively improved in many skills. In terms of the selected principles, there are many new operating methods developed. This makes the types of products have more different classifications, and also allows people in these aspects. They all got an excellent experience, and the selection time has a richer selection. The following editors will share with you what are the classifications of the experimental bench?

The experimental table can be divided into a central table, a side table, a cleaning table, an equipment table, a chromatography table, a work table, a cleaning table, a physics table, etc. according to the effect; it can also be divided into an all-steel experimental table, a steel-wood experimental table, The last three items of aluminum-clad wood experimental benches and all-wood experimental benches are gradually being updated.

I. Classification

1. All-wood structure: This is the commonly used method at home and abroad. It is lighter and more sensitive, and can be made into various unit combinations. The disadvantage is the high consumption of wood.

2. Steel-wood structure: This structure is composed of steel bracket, cabinet, table top and ground feet. The steel bracket is made of thin-walled steel, the feet of the foot bracket have fixing screws, and the pipe rack space is left between the steel brackets. The cabinet is made of wooden components and can be hung sensitively on a steel stand. Although this material has an anti-corrosion coating on the outside, it inevitably rusts and is generally used in instrument profiling rooms. The advantages of steel laboratory furniture: solid, beautiful, can be used for more than 10 years, adhere to no deformation, can accept strong acids, strong alkalis, is the development direction of laboratory furniture.

3. All-steel structure: It consists of a steel bracket, an all-steel cabinet, a table top and a foot. The steel bracket is made of thin-walled steel, the feet of the feet have fixing screws, and the space of the pipe rack is left between the steel brackets. Although this material has an anti-corrosion coating on the outside, it inevitably rusts and is generally used in instrument profiling rooms. The advantages of steel laboratory furniture: solid, beautiful, can be used for more than 10 years, adhere to no deformation, can accept strong acid, strong alkali, is also the direction of the development of laboratory furniture.

Classification by experiment

There are many types of chemical experiment benches, instrument experiment benches, high-temperature benches, sky channels, and wash benches. The experimental bench is located in the laboratory center according to the layout of the laboratory, and is called the island experimental bench (central channel); the end of the experimental bench against the wall is called the peninsula experimental bench; if one of the long sides of the experimental bench is called the side experimental bench ( Side table). Reagent racks, washstands, and ware cabinets to which it wants to adapt are also different.

Some people also divide the test bench into single-sided test benches and double-sided test benches.

Three, according to the structure: divided into fixed and combined

1. Fixed experimental bench: There are many ways of fixed experimental bench, which are still widely used. Common countertops are supported by reinforced concrete structures and brickwork, wooden ware cabinets under counters, white tiles, terrazzo, marble or natural granite on the countertops. These test stands are solid, durable, high temperature resistant, and stable. They are commonly used in high-temperature furnace stands and photometric instrument stands, but the shortcomings of such experimental stands are also obvious.

2. Combined experimental bench: Depending on its own structure, it is divided into several independent parts, which can be assembled separately after production. It can be sensitively arranged in the laboratory, convenient for transportation, and convenient for serial production.

In daily life, many researchers in physics and chemistry will stay in the laboratory all day long. For some people, natural generation has a blind pursuit of experiments. Every experiment is regarded as a common stimulus and enjoyment. This is why some people feel headaches when they see physics and chemistry, and some people can become this. Outstanding talent.
