MANOMETER VACUUM & PRESSURE GAUGE
Vacuum and Pressure GaugeManometer Let displacement illustrate the effects of vacuum and pressure for you! This unit is used to measure vacuum and pressure by means of displacement. A U-shaped manometer tube, with arms one meter long is mounted on a wooden support with a cast iron base. A liquid is then placed inside the tube to act as an indicator when pressure or a vacuum is introduced. Oil can be substituted for mercury as the liquid to be displaced. The glass tube is open on both ends. Instructions provided. (Weight & Dimensions).

BOYLE'S LAW J TUBE APPARATUS
Boyle's Law Apparatus & Supplies
This device is one of the classical forms of Boyle's Law, frequently described in experiment manuals. Consists of a funnel tube and a stopcock tube, connected together by a piece of flexible tubing, and running parallel to one another on aluminum rods. This allows one of the tubes to be raised higher or lower than the other and then locked in place. A meter stick is mounted between the two glass tubes, which allows for the measurement of pressure. This unit stands vertical on top of a cast iron base. Please note, mercury is not included. A heavy-weight oil can be used as a substitute for mercury. (50" x 4" x 6"; 6.2lbs).Price - $206.40
