General information

CH-100 and Combitherm-2 CH 3-150, dry-block thermostats with heating and cooling

function, are designed to thermally stabilize materials at a wide range of temperatures. Built-in
Peltier elements allow fast and precise cooling, and heating plates – heating of the materials
according to used methods.

Model CH-100 with built-in blocks (on request) is intended for micro quantities of
reagents, in volume range from 0.5 to 2.0 ml. Temperature setting range is from -10°C to
+100°C. Model features exceptional temperature maintenance stability and uniformity, as well
as high heating and cooling speed.

Model Combitherm-2 CH 3-150 with changeable blocks is designed for increased
versatility. Temperature setting range is from -3°C to +20°C for cooling block and from +25°C
to +150°C for heating block. Combitherm-2 consists of two independent modules for
interchangeable blocks, cooling and heating, combined in a single unit. Control panel is divided
in two parts for separate control of cooling and heating blocks. Blocks are controlled
independently, with possibility of setting up to 16 custom programs for different temperature
and thermostating time. Seven thermoblocks are available, for different size and quantity of
tubes.

Models can be used in:

 Molecular and cell biology, for nucleic acid extraction and analysis.
 Protein analysis (denaturation).
 Biochemistry, for analysis of enzyme processes.
 Chemical laboratories, in matter composition analysis.
 Food and environmental investigation laboratories, in composition analysis of food

and cosmetics.

Depending on the model, different quantities of microtubes of different volumes can
be placed in the thermostat.

- (Model CH 3-150) Plug the power cable into the socket on the rear side of the unit,

and position the unit with easy access to the power switch and plug.

- (Model CH-100) Connect the external power supply and the power cable. Plug the

external power supply into the socket on the rear side of the unit and position the

unit with easy access to the power switch and plug.

4.4. Heating or cooling block installation and replacement (model CH 3-150).
Caution! Heating/cooling block surface may become very hot or cold during

the operation. Avoid touching the block or heating/cooling surfaces.

Change the blocks only at room temperature.

- Use the extractor tool for removing blocks. Screw the tool into a threaded hole in

the middle of a heating/cooling block and lift it out. Unscrew the tool.

- Ensure that the heater bed and the block are clean in order to ensure good thermal

contact between unit and the block, resulting in optimal temperature control

performance.

Operation

Recommendations during operation

Please check the tubes before using, be sure that tubes are heat resistant. Don’t heat

the tubes over the melting point of the material they are made of. Remember that

thin-walled tubes have a higher thermoconducting factor.

 Microtube caps can open under the action of high temperature (> 85°C), thus causing

sample volume shrinkage or potential health risk when working with infected material.

To prevent such cases, use microtubes with cap lock of Safe-Lock® type.

 Do not fill tubes more than 3-5 mm over the level they are immersed in the heat block.

5.1. Working with model CH-100.

Fig. 1. Control panel of CH-100

5.1.1. Connect the external power supply to a grounded power socket. Switch on (position I)

the power switch on the rear panel of the unit.

5.1.2. The unit will turn on and the following readouts will be shown on the display:

- In the upper line Set: previously set time and temperature parameters;

- In the lower line Actual: operation status (S – stopped), timer indication STOP and

current temperature.

5.1.3. Temperature setting. Use the ▲ and ▼ T (ºC) keys (fig. 1/5) to set the required

temperature. Values are shown on display (upper line, fig. 1/3). Temperature incre-

ment is 0.1ºC. Pressing the key down for more than 2 s makes the values change

quicker.

5.1.4. Press the RUN/STOP T (ºC) key (fig. 1/8) to start heating or cooling. The corres-

ponding operation status is indicated on the display, H for heating, C for cooling

(fig. 1/1). Current temperature value is shown on display (lower line, fig. 1/5).

5.1.5. To stop the heating or cooling, press the RUN/STOP T (ºC) key again. It takes a few

moments before the heating or cooling process stops and the operation mode

indicator shows S, for stopped.

5.1.6. The set temperature can be changed during operation without stopping the process.

5.1.7. After thermal stabilisation of the unit (i.e. after set and current temperatures equalize,

fig. 1/3), open the block lid, place samples and close the lid.

5.1.8. Timer setting. The unit is equipped with an independent timer for convenient control

over the samples heating/cooling time.

5.1.9. Use the ▲ and ▼ TIME keys (fig. 1/4) to set the required time period. Values are

shown on display (upper line, fig. 1/2). Time increment is 1 minute. Pressing the key

down for more than 2 s makes the values change quicker.

5.1.10. Press the RUN/STOP TIME key (fig. 1/7) once to start the timer. The elapsed time is

indicated in the lower line of the display (fig.1/2). When the set time is reached, the

timer stops and a sound signal is heard.

Calibration

6.1. The device is precalibrated at the factory (calibrating coefficient is 1.000) for operation

with temperatures measured by a sensor in the heating block.

6.2. To change the calibration coefficient, hold the RUN/STOP TIME key (fig. 1/7, CH-

100) or Start Stop (fig. 2/7, CH 3-150) key pressed for more than 8 s to activate

calibration mode. The calibration mode appears on the display (fig. 3).

6.3. Restoring factory settings. Set 1.000 value using the ▲ and ▼ Temp or T (ºC)

keys as shown on fig. 3/1 to restore the factory settings. Press the RUN/STOP TIME

or Start Stop key once to save the changes and exit the calibration mode.
Note. For model CH 3-150, coefficient value changes are recommended

after the unit has reached 30°C temperature.

6.4. Calibration procedure.

6.4.1. Install independent sensor (0.5°C accuracy) into microtubes placed into the block

sockets.

6.4.2. Set the required temperature in operation mode (e.g. 40°C).

Fig. 3. Control panel in calibration mode

6.4.3. After the unit reaches the set temperature (when the set and current temperature

readings equal) leave the unit for 30 min for thermal stabilization.

6.4.4. Let us assume that the readings of independent sensor is 39°C, but the display’s

actual temperature is 40°C (fig. 3/4). Then it is necessary to add 1°C correction.

6.4.5. Hold the RUN/STOP TIME or Start Stop key pressed for more than 8 s to activate

calibration mode. The following parameters will be shown on the display (fig. 3).

6.4.6. Using the ▲ and ▼ Temp or T (ºC) keys, change the calibration coefficient (fig. 4/1)

so that the new temperature value (fig. 4/2) corresponds to the independent sensor

temperature. In our example, the calibration coefficient will be 0.974.
Note. Calibration coefficient can be changed in range from 0.936 to 1.063

with increment of 0.001. This calibrating coefficient will correct
temperature through all the operation range of the block.

Note. For model CH 3-150, coefficient value changes are recommended

after the unit has reached 30°C temperature.

6.4.7. After finishing the calibration, press the RUN/STOP TIME or Start Stop key once to

save the changes and exit the calibration mode.

6.4.8. The display will show calibrated temperature as shown on fig. 5/1 and the unit will

continue thermal stabilization according to the previously set temperature.
