Select your stirring hotplate
Heat-On is compatible with most leading brands of stirring hotplate with a

Set-Up
Important Note
Always fully read the instructions of any third party equipment, such as stirring
hotplate or temperature probe thoroughly, to ensure you are not contravening
any safety recommendations or manufacturers warranty when used in
conjunction with Heat-On.
Heat-On Instructions
Warning
When placing oil baths, sand baths, polymer coated or aluminium blocks etc onto a stirring hotplate the increased surface
area will reflect heat back to the stirring hotplate. In such instances care should be taken to ensure that the hotplates
external housing does not exceed the maximum temperature recommended by the manufacturer. Such overheating can
cause damage to internal and/or external parts and lead to failure of your stirring hotplate.
Warning
Always refer to the manufacturers operating instructions for your stirring hotplate before using it with Heat-On to be sure
of any limitations or safety restrictions.
Do you need an adapter plate?
The Heat-On blocks and multi-well holders have a single recess in the base to locate onto
your stirrer hotplate. Some hotplates, such as the Carousel Stirring Hotplate and IKA, have a
smaller top plate diameter (135mm) so some movement will be noticed between the block
and the top plate.
If you feel this is unacceptable an adapter plate can be purchased. This optional aluminium
adapter plate for 135mm diameter top plates is available from Heidolph: -

Optimising the temperature performance of Heat-On
The heating performance of Heat-On will be affected by:
1. The limit of the maximum operating temperature of the stirring hotplate.
2. Heating power (Watts) of the stirring hotplate.
3. Flatness of the top plate on the stirring hotplate.
4. Ambient temperature.
5. Load to be heated.
6. Maximum housing temperature of the stirring hotplate.
7. Whether you use a separate temperature controller (probe) see overleaf.
Important Note
Heat-On blocks can be used up to 200˚C
without damage to the block. Temperatures
up to 260˚C can be achieved but some
minor surface degradation may occur.
