Vacuum Techniques

In this experiment you will learn about vacuum technology and how to use it for measurements.


The term vacuum refers to the condition of an enclosed space that is devoid of all gases or other material content. It is not experimentally feasible to achieve absolute vacuum, although one can approach this condition very closely. In this experiment you will:

  1. Learn about different vacuum equipment including pumps, pressure gauges and flowmeters.
  2. Create a vacuum to allow direct measurements of atmospheric pressure.
  3. Measure the conductivity of different tubes for gas flow and calculate the viscosity of the gas.
