Isoteniscope

An Isoteniscope is a device used to measure the vapor pressure of liquids. It consists of a submerged manometer and container holding the substance whose vapor pressure is being measured. The open end of the manometer is then connected to a pressure measuring devise. A vacuum pump is used to adjust the pressure of the system and purify the sample.
