What is the chemical laboratory equipment? 2011-08-10
Chemicals are always heard, then how the chemicals come from? This would be due to Chemistry Laboratory Apparatus, because these things have the appearance of chemical agents and application of these products. A common classification of the instrument The main purpose is generally based on the different instruments, laboratory instruments can be commonly divided into the following eight chemical categories: (A) the measurement type Used to measure mass, volume, temperature, density and other instruments. Such instruments are mostly glass container. There are burette, pipette, graduated cylinder, measuring cup and so on. (B) the reaction type Instruments for chemical reactions, but also part of the heated equipment. Such instruments are mostly glass or ceramic burner. There are test tube, flask, evaporating dish, crucible. (C) the container class Used to hold or storage of solid, liquid, gas and other chemical reagents of reagent bottles. (D) separation of class Used for filtering, sub-liquid extraction, evaporation, burning, crystallization, distillation and other separation and purification operation of the instrument. The main funnel, separatory funnel, evaporating dish, flask, condenser, crucibles, beakers, etc. (E) solid grip class For fixed, holding a variety of equipment, supplies or equipment. There are metal trap, hoop, Utility Stand with Clamps, funnel racks. (F) heating category Supplies or equipment for heating. There are test tubes, beakers, flasks, evaporating dish, crucible. (G) supporting class For the assembly, when connecting the instrument used in glass, glass valve, rubber tubes, rubber stoppers and other supplies or equipment. (H) Other Inconvenience to other types of ownership of the equipment or supplies. Therefore, the liquid chemical laboratory is sensitive to mixing research and is derived, and may attempt to place the invention. Like other exclusive chemistry lab chemistry laboratory-based experiments are also some special tools and equipment. Choose the right chemical laboratory equipment, so you can do experiments and teach students to play a very good effect.
