2. Description
The steam generator is used as a source of heat in
experiments which require the generation and use
of steam (e.g. thermal expansion apparatus).
The steam generator is made up of an adjustable
hot plate with a thermal circuit breaker, upon
which a metal container has been mounted. The
metal container is held in position on the hot plate
by a securing clamp and can be shut by means of a
cork lid with a steam outlet pipe.
The steam generator is available for two different
mains volatages. U8624650-230 is designed for 230 V
(±10 %) mains supplies, while the U8624650-115
model is for 115 V (±10 %) supplies.

4. Operation
• Half fill the container with water and close it
with the cork cover. Press the lid firmly onto
the vessel.
• Secure the container onto the hotplate by
means of the retaining clamp.
• Attach the hose and connect it to the experi-
mental apparatus. Make sure that the hose is
not obstructed or crimped in such a way as to
prevent flow.
• Connect the hotplate to the mains supply and
set the heating level using the control knob.
Level 4 is sufficient for most experiments.
• Carry out the experiment.
• After completing the experiment, allow the
steam generator to cool for about 30 minutes
before removing the hose or the retaining
clamp.
• If the cork lid is difficult to remove, blow hard
down the hose to release it.
