Technical Description

The Model 2011 Gas Pressure Syringe is a calibrated, 60 mL syringe.   The volume in the syringe may be adjusted by moving the plunger in the syringe to the desired volume.  An included short flexible hose with a Luer fitting is used to connect the syringe to a MicroLab gas pressure input, or to a Luer fitting in another gas experiment.

A three-way valve permits opening either the syringe or the hose to the MicroLab pressure input to ambient pressure during set-up.  

The handle of the valve points to the valve input that is closed.

For Boyle's Law experiments, we recommend that students start the experiment at a volume of 20 mL and ambient pressure.   Then pull the plunger out to take volume/pressure readings at 5 mL increments.  It is difficult to pull hard enough to reduce the pressure by more than a factor of two (40 mL).

The internal pressure sensor in the MicroLab will measure 0-2 atm pressure.   As a safety feature to protect the sensor, the hose will pop off the sensor at about 3 atm pressure.

By reducing instead of increasing pressure during the experiment, there is no possibility of blowing the hose off the sensor.
