The distillation apparatus requires instruments such as an iron stand, alcohol lamp, distillation flask, thermometer, condenser tube, long conduit, asbestos mesh, branched conical flasks, rubber stopper, bullwhorn tube, beaker, and so on. Distillation is a mass transfer process that separates components of a liquid mixture by taking advantage of differences in volatility of the components.
1, iron frame table
The iron frame table consists of a large mass of the base and fixed to the iron base and perpendicular to the base of an iron rod. According to different experimental content, often equipped with up and down to move the iron ring, flask clamps, burette clamps, condenser tube clamps and other additional equipment.
2, alcohol lamp
Alcohol lamps are alcohol-fueled heating tools, widely used in laboratories, factories, medical, scientific research. Because of the heat generated during the combustion of alcohol lamps, can be heated to other experimental materials.
3, thermometer
Thermometer can accurately determine and measure the temperature of the tool, divided into pointer thermometer and ? Digital thermometer. According to the difference in the purpose of use, has designed and manufactured a variety of thermometers.
4, condenser tube
Condenser tube is used as a laboratory equipment to facilitate the role of condensation, condensation or reflux, usually by a mile and two glass tubes, where the smaller glass tube through the larger glass tube.
5, long conduit
The role of the conduit is to guide the gas and semi-trust condensation, reflux.
6, asbestos mesh
asbestos mesh is used to heat the liquid on the tripod in the alcohol lamp on the wire mesh, which consists of two pieces of wire mesh sandwiched between a piece of asbestos soaked with water to dry cotton-like products, is a commonly used in chemical experiments in the chemical apparatus.
7, branch mouth conical flask
A kind of chemical laboratory common glass instruments, German chemist Richard Erlenmeyer invented in 1861. Generally used in titration experiments. In order to prevent the titrant drop down splash, resulting in experimental error, the bottle will be put on the magnetic stirrer.
8, rubber stopper
Rubber stopper can control the material in the container, only let the generated gaseous material escape.
9, bullhorn tube
Bullhorn tube, also known as the receiver, the receiver tube, is designed to collect the role of the liquid in the condenser tube.
10, beaker
Beaker refers to a common laboratory glassware, made of glass, plastic, or heat-resistant glass.
