Laboratory instruments and equipment are test tubes, beakers, evaporating dishes, crucibles, alcohol lamps, and Brinell's funnels.
Laboratory instrumentation, the instruments used in specific experiments in the natural sciences, mainly used in physics, chemistry and biology. Modern commonly used experimental instruments are test tubes, beakers, evaporating dishes, crucibles, alcohol lamps, Brinell's funnel, gas-washing flasks, drying tubes, tray balances, measuring cylinders, volumetric flasks, burettes, measuring devices and so on.
Biochemical incubator: low-temperature storage medium and microbial culture, environmental testing, etc..
High and low temperature test chamber: alternating, hot and humid, for industrial and mining enterprises, laboratories, scientific research units for high and low temperature environmental testing, detection purposes.
Aging test chamber: can be compiled temperature, time, heating rate, etc., suitable for a variety of aging test requirements.
Water bath: constant temperature digital display, for drying, concentration, distillation, impregnation of chemical reagents and biological products, can also be used for water bath constant temperature heating and other temperature tests.
Importance of Laboratory Instruments
Laboratory instruments homemade, refers to the lack of readily available commercialized instruments to buy, or although bought but can not afford to buy the case, looking for relevant materials to develop and produce their own experimental equipment to meet the teaching requirements.
The significance of the main lies in:
1, the transitional solution to the lack of instrument resources, and the original old instruments and the new curriculum and new teaching materials to match the problem of poor, for the comprehensive and effective development of experimental teaching to provide the conditions of space.
2, but also for the development of industrialized commercial instrumentation to create the conditions of the prototype.
3, cultivate students' innovative spirit and practical ability. Students' teaching aids (learning aids) homemade activities, is a form of physical experiment teaching activities, is an important part of physical experiment teaching activities.
4, the production process of homemade teaching aids is a student brain process, from the initial concept in the mind, hands-on design, and then to the middle of the process of repeated consideration of the modification of the need for their own thinking in order to carry out the next step of the production, to the final completion of the middle of the experience is in fact a discovery of the problem, the problem-solving process, not only to exercise the hands-on ability of the students at the same time it is the students to develop a positive thinking good The first step is to make the product more attractive to the public.
