Glassware is widely used in chemical experiments for the following reasons. First of all, the glass is transparent, which is good for observing the reaction inside. Secondly, the chemical properties of glass are stable, and it is not easy to react with acid and alkali. In addition, many glassware are temperature-resistant. How to clamp glassware is an essential skill in chemistry experiments, watch the video to the right to learn.
Quick instructions
Place the iron stand on a level table with the base turned to the back.
Carefully pass the condenser tube through the iron ring and connect it to the conical flask.
Adjust the position of the iron ring up and down, it should be controlled at the upper part of the middle of the condenser tube, and then tighten the iron ring knob.
Questions to test you've understood how to do the technique properly.
There are many types of glassware, think about how to clamp other glassware in addition to the assembly of the flask and condenser mentioned in the video. （How to assemble a simple distillation apparatus?）
