RUBENS’ TUBE LA 50-550
This apparatus provides a dramatic visual presentation of wave
motion based on the original apparatus designed by Henrich
Rubens in 1905.
There are various safety precautions to be observed and these
should be studied carefully before use.
The system uses the high and low pressures in a sound wave to
vary the gas pressure and hence the flame height in the tube.
INTRODUCTION

dents.
Use low gas pressure.

materials.

mins. to avoid excessive temperatures.
AFTER USE

fore storing.
