Which glass instruments in laboratory equipment can be heated
Laboratory equipment is an instrument used in specific experiments in natural science. There are many types of experimental instruments in the laboratory, including instruments for heating, instruments for separating substances, measuring instruments, etc. The following Shandong experimental instruments will be introduced to you. What are the experimental instruments used for heating.
(1) Alcohol lamp: a heating source commonly used in chemical experiments.
(2) Beaker: It is used as a reaction container for preparing solutions and larger quantities of reagents, and is used at room temperature or during heating.
(3) Crucible: mainly used for high temperature burning of solid substances.
(4) Evaporating dish: used for evaporating liquid or concentrating solution.
(5) Test tube: a container used to hold a small amount of medicines and react with a small amount of reagents at room temperature or under heating, and can be used to prepare or collect a small amount of gas.
(6) Flask: It is used for a container with a large amount of reagents and liquid substances participating in the reaction, which can be divided into round-bottomed flasks, flat-bottomed flasks and distillation flasks. All of them can be used to assemble gas generating units. Distillation flasks are used for distillation to separate miscible substances of different boiling points.
