5.3 Inserting tubes and plates
1. Select a suitable exchangeable thermoblock and mount it (see Inserting exchangeable
thermoblocks on page 18).
2. Place the tubes or plate on the thermoblock.
For optimum temperature control transfer the micro test tubes to the exchangeable
thermoblocks using IsoRacks. The IsoRack reduces the heat exchange of the thermoblock
with the environment. If necessary close the IsoRack lid.
3. If using the MTP thermoblock: put the lid on.
5.4 Time counting mode
The time counting function enables temperature control and/or mixing for a limited period of time.
The temperature will be held constant by the device even after the set time has elapsed.
There are two ways to measure the time of the temperature control processes:
•
Time control:
Time counting begins immediately when "Start/Stop" is pressed. The indicator lamp in the
key lights up.
•
Temp control:
Time counting only starts when the nominal temperature value has been reached.
During the time in which the device controls the temperature to reach the nominal
temperature, the colon of the time display flashes. This signals that the device is active.
When the nominal temperature has been reached and time counting starts, the indicator
lamp of the "Start/Stop" key lights up.
To terminate the process early, press the "Start/Stop" again.
1. Hold the "Progr." key while switching the device on. Hold the key until the display either
shows time control or temp control.
2. Using the "Time" arrow keys, set time counting.
On the display, the time will appear on the bottom left. The time can be set from 1 minute to
99 hours 59 minutes. Pressing the key once will alter the setting by one minute. During the
run the remaining run time will be displayed in minutes. The last minute is counted down in
seconds.
WARNING!
Caution! Microplates melt at extremely high temperatures.
 Only heat microplates made of polystyrene to a maximum 70 °C.
