Inficon MPG400 vacuum gauge
MPG400 is a member of full range vacuum gauge (gauge that can measure both low vacuum and high vacuum). It applies a Pirani detector for low vacuum (>1Pa) and a cold cathode for high vacuum (<1Pa). Here are two very good videos for how Pirani gauge and cold cathode gauge work. The electronics is separated. …

Make Crystals via Vacuum Distillation
Table of content Introduction Metal Distillation Theory Experiment The End Reference Introduction Vacuum distillation is a widely applied in laboratories. Not only can vacuum environment prohibit most contaminations, but it also allows distillation to happen at lower temperature, which is both environment-friendly and time-saving. For most people, vacuum distillation is only a familiar process of …
