英语翻译
If an apparatus cracks or breaks due to thermal or mechanical shock,the hazards are sufficient to make it desirable to consider using quartz apparatus since it is necessary in many experiments to chill perchloric acid rapidly from the boiling point.Glass-to-glass unions,lubricated with 72% perchloric acid,seal well and prevent joint freezing arising from the use of silicon lubricants.Rubber stoppers,tubes,or stopcocks are incompatible with perchloric acid.
