NOTICE
The heated lid automatically switches off at a temperature difference of >75 °C
between the block and the heated lid. At these low block temperatures, sample
condensation on the tube lid is no longer to be expected. In addition, it supports
a longer service life of the Peltier elements in the block, since no unnecessary
cooling against the heating cover is required.
8.5 Preheating the heated lid
The heated lid can be set to preheating ON or OFF using the corresponding buttons:
Preheat heated lid Off
Preheat heated lid On
If the preheating mode is activated, the heated lid is first heated up to the programmed temperature
while the sample block is held constant at 25°C. After the heated lid reaches the target temperature,
a 40 second equilibration phase follows. Then the sample block starts to heat up from 25°C to the
first programmed target temperature.
Note : For most applications, we recommend to set the preheating mode to ON .
