CAMPAIGN OF VACUUM WITH MANUAL PUMP
This instrument is composed by a transparent campaign and a manual
pump of vacuum both made with ABS plastic in order to realize physic
experiments with vacuum.
The campaign gives security to perform
experiments without implosion danger or break and it has a pressure gauge
and a scape valve.
A rubber gasket is on the base and it achieves a perfect sealing of the
campaign. There is a manual pump on the base that provides a rapid and
efficient air scape.
Note: the explosion or contact with solvents or vapors organic or to other
reagents is not allowed. This instrument is not autoclavable.
Practice
Introduction
We are going to observe the effect of the pressure on a balloon reducing
the pressure on the outside.
Objetive
Check that the pressure of a gas changes its volumen.

Explanation
Normally, a ballon increases in volume when it is swollen. The pressure
inside is higher than outside thus the balloon expands until the two
pressures are equal and are in equilibrium.
1.
1. P1 and P2 are equal the atmospheric pressure.
2. Before start the campaign P2 decreases and the balloon increase in
volume to achieve the equilibrium.
QLB006
1. Fill the balloon with air only a Little.
2. Put it into the campaign of vacuum
3. Start and observe
4. The balloon will increase in volumen
5. Desconect the campaign of vacuum to
