Linear Expansion Apparatus with Three Pointers 1000830
Instruction sheet
02/13SF
1 Steam generator with silicone hose
2 Base strip
3 Sample tubes
1. Safety instructions
The glass tube is breakable. Risk of injury!
• Handle the apparatus with care.
Danger of serious burns! It is a property of all
the materials that these tubes are made of that
they store heat.
• Therefore, allow the tubes to cool after every
experiment.
2. Description
The thermal expansion apparatus is used for the
simultaneous measurement and comparison of
the coefficient of thermal expansion of tubular

bodies made of different materials.
Three sample tubes are mounted on an alumin-
ium base strip. The free end of each tube rests
on a pilot bearing. The thermal expansion of the
tubes is demonstrated by three pointers, each of
a different colour, on a mirror scale.
