1. General description
Cole-Parmer block heaters are designed to
accurately control the temperature of test tubes
and other small containers using heated
aluminium blocks drilled with holes of the
appropriate size for the containers in use. A
large variety of blocks with different holes for
different sizes and type of container are available
– see section 7.
The blocks are fitted into the recess in the top of
the instrument (see figure 1) and heated from
below. All blocks are fully interchangeable and
blocks for different sizes of container may be
used in a block heater at the same time.
The large thermal mass of the aluminium blocks
allows very accurate and stable temperature
control.
Perspex safety covers are available as accessories
for protection in the event of tubes “spitting”.
These also help improve temperature uniformity
within the blocks by excluding draughts.
2. Preparation for use –
All models
1. Follow the instructions for Electrical
Installation given in section 8 of this manual
and connect the instrument to the electricity
supply – DO NOT SWITCH ON.
2. Choose aluminium blocks with holes suitable
for the containers to be heated.
3. Carefully place the appropriate number of
aluminium blocks into the recess in the top of
the instrument – see figure 1.
1
N.B. The plate at the bottom of the recess
and the base of the aluminium blocks must
be kept scrupulously clean to allow good
thermal contact. If foreign matter, especially
particulate matter, is present the
performance of the instrument will be
impaired.
4. Place the containers to be heated into the
holes in the aluminium blocks.
5. Fit safety cover if required. This may simply
rest on the top of the block heater or be
hinged by using the screws provided. These
should be located in the holes at the top rear
of the block heater (see figure1).
6. The instrument may now be switched on and
the desired temperature set.
3. Temperature setting
3.1 Digital models BH-200D-2, BH-200D-2-HT,

6. Pressing these buttons once adjusts the
setting up or down in 0.1°C increments.
Pressing and holding will scroll the display
rapidly up or down until the desired value is
reached.
7. When the desired temperature is displayed
release the “set” button to revert the display
to showing actual temperature.
8. The instrument will now begin to heat the
aluminium blocks to this temperature.
9. The light labeled “heat” on the control panel
will illuminate continuously during the heating
phase but will begin to flash when the set
temperature is approached.
10. Once the set temperature is reached the
instrument will maintain the blocks at this
temperature until the setting is changed or
the instrument is turned off.
11. Containers may be removed from or added to
the blocks at any time during operation.
N.B. Care must be taken if placing cold glass
vessels into pre-heated blocks. The resulting
thermal shock may cause the container to
break.
12. After use the instrument should be switched
off at the rear and allowed to cool. It should
then be disconnected from the electricity
supply. Note that when next used the
instrument will have retained its previous set
temperature.
3.2 Dual control digital models BH-200DC-2 &
BH-200D-2-HTC
Models BH-200DC-2 & BH-200D-2-HTC
accommodate 2 aluminium blocks with
independent temperature controls so that each
block may be set to a different temperature. The
layout and operation of the controls for each
block is exactly as described above.
If using this model with only one block in place
the side with no block should have its set
temperature adjusted to 30°C.
3.3 Analogue model BH-200-2
1. Switch on using the switch located at the rear
of the instrument – see figure 2.
2. The “power” light will illuminate - see figure 4.
3. The desired temperature may be set using the
control knob labeled “heat” on the right
hand side of the control panel – see figure 4.
If turned to the position labeled “off” the
heater will be switched off. Otherwise the
scale around the knob will give guidance as
to the set temperature.
4. The instrument will now begin to heat the
aluminium blocks to this temperature and the
light labeled “heat” on the control panel will
illuminate – see figure 4.
5. If the temperature of the blocks exceeds
50°C the red light labeled “hot” will begin to
flash to warn that the blocks are too hot to
touch – see figure 4. This will continue even
if the heater is turned off using the knob on
the control panel so long as the instrument
remains connected to the electricity supply
and turned on with the switch at the rear.
6. Once the set temperature is reached the
instrument will maintain the blocks at this
temperature until the setting is changed or
the instrument is turned off.
7. Containers may be removed from or added to
the blocks at any time during operation.
N.B. Care must be taken if placing cold glass
vessels into pre-heated blocks. The resulting
thermal shock may cause the container to
break.
8. If the temperature needs to be set accurately
it may be measured using a thermometer
placed in the small hole in the top of the
block. The position of the control knob
should then be adjusted to raise or lower the
Figure 4 - analogue controls

temperature as required. If this setting needs
to be repeated regularly it is possible to leave
the control knob in position and use the
switch on the rear of the instrument to turn it
on and off. Note that switching off at the
rear will cause the hot warning light to stop
flashing.
9. After use the instrument should be switched
off at the rear and allowed to cool. It should
then be disconnected from the electricity
supply.
4. Calibration –
Digital models only
These units are calibrated during manufacture
using blocks designed for 16mm tubes. The
different mass of aluminium in blocks designed
for other sizes or types of container can cause
small discrepancies between the displayed
temperature and the actual temperature of the
blocks.
If the block heater is to be used with other blocks
and very accurate temperature setting is required
then the unit should be re-calibrated for the
blocks to be used.
You will need an accurately calibrated
thermometer for this procedure to be
worthwhile. The block heater can only be as
accurate as the thermometer used to
calibrate it.
Follow the procedure outlined below.
1. Begin with items that are cool.
2. The blocks should be pushed firmly to the
right hand side of the recess with no air gap
between blocks. The right hand block will be
used as the calibration block.
3. Switch on the unit and set the temperature
display to 30°C following the procedure
outlined in section 3.1
4. Press all three buttons together and hold for
5 seconds until the amber “heat” light stops
flashing and remains permanently on.
5. Self-calibration will now begin and the unit
will begin to heat.
6. After approximately 30 minutes the unit will
have stabilized at approximately 40°C and the
display will change from showing
temperature to read (EEEE).
7. Accurately measure the block temperature
within the thermometer hole in the right hand
block.
8. Press the set button and release
9. Press and hold the set button and use either
the up or down buttons to adjust the display
temperature to equal the actual temperature
measured.
10. Press the up and down buttons together to
confirm the value. The amber “heat” light will
stop flashing and remain permanently on.
11. Self-calibration will now continue and the unit
will ramp up to approximately 5°C below
maximum, i.e. either 125°C or 195°C
depending on model..
12. After approximately 30 minutes the unit will
have stabilized and the display will change
from showing temperature to read (EEEE).
13. Accurately measure the block temperature
within the thermometer hole in the right hand
block.
14. Press the set button and release
15. Press and hold the set button and use either
the up or down buttons to adjust the display
temperature to equal the actual temperature
measured.
16. Press the up and down buttons together to
confirm the value.
17. The unit will now begin to control with the
new calibration parameters.
18. Allow 30 minutes for the temperature to
stabilize.
19. Check that both the display temperature and
the thermometer temperature are now
between 124°C and 126°C or 194°C and
196°C depending on model.
20. Press the set button and release to confirm
the calibration. The set temperature will revert
to 30°C.
21. Reset the set temperature to maximum (130
or 200°C) and allow a few minutes to confirm
that the unit actually achieves that
temperature.
22. Calibration is now complete and the unit may
be used normally.

5. Factors affecting
calibration and accuracy
In order to get the maximum accuracy from the
equipment and to ensure accurate calibration the
factors listed below should be considered as they
will all affect performance.
1. The base of the blocks and the heated surface
in the unit must be scrupulously clean to
ensure good contact.
2. The blocks should be pushed firmly together
to the right hand side of the recess
3. The thermal radiation from the blocks can be
affected by surface condition and affect
accuracy. The top surface should be kept
clean and shiny.
4. If the unit is used in an area of strong drafts
such as inside a fume hood there can be a
temperature gradient across the blocks. In
this case the safety cover should be used to
protect the blocks from the air flow.
5. During calibration the temperature probe used
should be a good fit in the hole in the block.
6. Removal of aluminium
blocks
N.B. Do not attempt to remove blocks until
the instrument has been switched off and
allowed to cool
The instrument is supplied with a special tool to
facilitate removal of the blocks.
This should be screwed into the thermometer
hole in the top of the block and then used to lift
the block clear of the instrument. An extension
piece is provided for use with long tubes.
There is a convenient storage groove located on
either side of the body casing – see figure 1.
7. Aluminium blocks and
accessories
The following range of aluminium blocks is
available. All are manufactured from anodized
aluminium and have an extra hole designed to
accommodate a thermometer if desired.

1. Description générale
Les réchauffeurs de blocs Cole-Parmer sont
conçus pour contrôler avec précision la
température des tubes à essais et autres petits
récipients à l’aide de blocs d’aluminium chauffés
percés de trous à la cote appropriée pour les
récipients utilisés. Une grande variété de blocs
comportant des trous différents pour différentes
tailles et sortes de récipients est disponible -voir
section 7.
Les blocs se logent dans le réceptacle sur le dessus
de l’instrument (voir figure 1) et sont chauffés par
dessous. Tous les blocs sont parfaitement
interchangeables, et les blocs destinés à des tailles
de récipients différentes peuvent être utilisés
simultanément dans le réchauffeur de blocs.
La grande masse thermique des blocs d'aluminium
permet un contrôle de température très précise et
stable.
Des couvercles de sécurité Perspex sont
disponibles comme accessoires de protection en
cas de “projection” des tubes. Ils permettent aussi
d’améliorer l’uniformité de la température dans
les blocs, en excluant les tirages.
