®
The upright vessel with three glass tubes is used to ob-
serve water levels in connected tubes, and also serves
as an overflow vessel for measurements of the volume
and density of solid bodies.
1. Safety instructions
• Handle the glass vessel carefully to avoid breakage
and resulting injury.
• Avoid exerting mechanical loads on the apparatus.
• Proceed carefully when interchanging the glass
tubes.
• Be careful when using coloured water not to let it
splash on your clothes, for example.
2. Description, technical data
The upright vessel consists of a glass cylinder in a plas-
tic base plate. Two outlets each with a GL screw con-
nection are located at the bottom for the purpose of
mounting either two differently shaped glass tubes, or
a dummy joint and an overflow tube.
Height: Approximately 300 mm
Diameter: 90 mm
Tube diameter: 10 mm
Screw connection: GL-17
2.1 Scope of delivery
1 upright vessel with a plastic base plate
2 differently shaped glass tubes
1 overflow tube with a drop outlet
1 dummy screw joint
3. Procedure
• It is practical to use coloured water during the ex-
periments.
• For experiments to observe liquid levels in con-
nected tubes, undo both the screw connections on
the upright cylinder.
• Mount the two differently shaped glass tubes and
screw them tightly into place.
• Fill the upright cylinder to approximately 2/3 with
water.
• Check the water level in all three vessels.
• As a demonstration, tilt the apparatus toward ei-
ther side and check the water level again in each
case.
• For experiments to determine the volume of solid
bodies, mount the dummy connection and the over-
flow tube with the drop outlet, and screw them
tightly into place.
• Position the measuring cylinder under the drop out-
let.
• Fill the upright cylinder with water until it starts to
flow out of the overflow tube.
• Empty the measuring cylinder of water.
• Immerse the sample body into the water vessel.
• To determine the volume of the body, read the level
of the displaced water which has overflowed into
the measuring cylinder.
