hank you for purchasing Heat-On
T
Please read this Instruction Manual thoroughly before operating your unit.
Introduction
Heat-On is a modular heating and stirring work station designed to accept either one or two round bottom flasks from 10ml to 5 litres.
Heat-On offers the following features and benefits:
• All Heat-On blocks are manufactured from solid aluminium providing excellent, even heat transfer to the
entire block, preventing hot spots.
• Sleek weight saving design reduces the mass of the block to be heated, improving heat-up times.
• Uniquely shaped deep wells maximise heated surface area to improve heat-up time and minimise the difference
between the block and solution temperature.
• Fluoropolymer coating gives added durability.
• Tests have shown that a 250ml flask of water can be boiled in under 9 minutes, 50% faster than the competition.
• All Heat-On blocks have a probe hole for use with separate temperature probe.
• 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.

Important WARNINGS
1. Please read these instructions completely before using your Heat-On Block.
2. Operate only in a fume cupboard with protective safety sash.
3. During and after heating take care not to touch the Heat-On block.
4. Risk of burns from hot blocks
Like oil baths, Heat-On blocks remain hot for some considerable time after the heating source has been switched off. A temperature
probe or temperature sensitive label can be used to indicate when blocks are too hot to touch.
5. Flask selection process
Heat-On is designed so that over sized flasks cannot fit through the slightly narrower opening at the top of the block well. This means
that all suitable flasks should sit at the bottom of the block well, be a loose fit and as such spin freely in the Heat-On well.
When a flask is inserted into the well it is important to ensure that the flask touches the bottom of the well and does not ‘catch or stick’
on the sides of the block well. If the flask is ‘catching or sticking’ it may be deformed and may result in jamming and even cracking of
the flask when the Heat-On block is cooling.
There is a simple rule when using glassware with the Heat-on: “If it does not spin, then throw it in the bin”. If the flask does not
spin freely then it is unsuitable for use in the Heat-On and an alternative flask should be used.
6. Starting and stopping your reaction
In an ideal situation you should load your glassware into the block when the block is at ambient (room temperature).
However in certain situations this may not be practical. In such circumstances you should note:-
a. You can use cold water to cool the block down rapidly, but take care with blocks above 100˚C as steam is a potential hazard.
b. It is generally safe to insert flasks into blocks that are below 50˚C, but the flask should be removed before the block temperature
drops below the start temperature as there is a small risk that the contraction of the block could crush the glass flask.
c. In all eventualities flasks should be removed at or above the temperature they were originally inserted; i.e. in the case of a flask
that is inserted at 80˚C, it should be removed when or before the block cools to 80˚C.
7. Chemical resistance
Anodised Heat-On blocks are resistant to the majority of solvents and splash resistant to dilute acids and alkalis at room temperature.
The fluoropolymer coated Heat-On blocks offer superior resistant to the majority of solvents, acids and alkalis.
Extended exposure to acids or alkalis will attack the surface of the Heat-On blocks. The stronger the concentration and the longer the
exposure time the more chance and intensity of any attack. Heat will also speed up and intensify any attack. e.g. hot concentrated
sulphuric acid will damage the fluoropolymer coated Heat-On blocks over a period of time. It is important to clean off any residual
chemical spills immediately after they occur.
8. Temperature range
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.

Set-Up
Select your stirring hotplate
eat-On is compatible with most leading brands of stirring hotplate with a
H
diameter of up to 145mm including the Radleys Carousel Stirring Hotplate
and the Heidolph (505-20000-00 or 505-30000-00) stirring hotplates.
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: -

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.

Important Note
Please note that typically temperature controllers should be set between
5˚C and 15˚C above the boiling point of the solvent to achieve a gentle reflux.
Warning
Temperature controller wire/cable should not come into contact with the HeatOn Block. Always rotate the block to ensure that the probe hole is nearest to
the probe socket on the stirring hotplate.
Optimising the stirring performance of your Heat-On
The Heat-On system uses the magnetic field of the stirring hotplate to stir your sample. The Heat-On blocks have been optimised to work
with leading brands of stirring hotplates with a top plate diameter of up to 145mm.
The stirring performance of Heat-On will be affected by:
1. The limit of the maximum stirring speed of the stirring hotplate.
2. Power and size of the magnet within the stirring hotplate.
3. Selection of an appropriate magnetic stirring bar for your chosen flask
4. Viscosity of sample.
Wide choice of magnetic stirring bars
The selection of an appropriate magnetic stirring bar for your chosen flask is key to the
performance of stirring within the Heat-On block.

left in block whilst heating they will become hot.
Warning
Extreme caution should always be used when lifting hot vessels or objects.
Please check with your laboratory safety officer to ensure that you are
complying with all relevant safety procedures.
Many laboratories do not permit the handling of hot liquids or objects
and therefore the use of the optional handles may not be permitted
within such a laboratory.
To increase user safety Radleys recommend the use of a retort stand with Heat-On blocks,
adding further stability to the system, particularly when using the larger blocks.
We find it best to locate the stand to the rear of your set-up thus avoiding any obstruction
when using hotplate controls.

Flask selection process
Heat-On is designed so that over sized flasks cannot fit through the slightly narrower opening at the top of the block well. This means that
ll suitable flasks should sit at the bottom of the block well, be a loose fit and as such spin freely in the Heat-On well.
a
When a flask is inserted into the well it is important to ensure that the flask touches the bottom of the well and does not ‘catch or stick’
on the sides of the block well. If the flask is ‘catching or sticking’ it may be deformed and may result in jamming and even cracking of the
lask when the Heat-On block is cooling.
f
here is a simple rule when using glassware with the Heat-on: “If it does not spin, then throw it in the bin”. If the flask does not spin

freely then it is unsuitable for use in the Heat-On and an alternative flask should be used.
Warning
Factors that could lead to a flask failure...
!
Description of Problem
1. The flask does not spin freely and therefore is deformed and is catching or sticking on the inside of the well. The flask may well crack
when the Heat-On block cools.
2. There is grit or an object between the flask and the well.
3. The flask was sealed with a closure or cap and there was a build up of pressure in the flask during heating.
4. The flask was scratched, or cracked and failed due to weakness.
5. The flask was not properly annealed during manufactured and has cracked due to stress.
Remedy
1. There is simple rule when using glassware with the Heat-on: “If it does not spin, then throw it in the bin”. If the flask does not spin
freely then it is unsuitable for use in the Heat-On and an alternative flask should be used.
2. Always thoroughly clean the Heat-On block before and after use.
3. Never heat sealed glass vessels, unless they are specifically pressure rated.
4. Never use glassware that shows signs of scratching, cracking or has chips, as this causes inherent weaknesses in the glass strength.
5. Always buy glassware from reputable sources.
