1 Wheel for exerting the contact pressure
2 Lid sealing button
3 Display
4 USB port
The device is controlled via a 7" touch screen display and the easy-to-use user interface.
The touch screen is installed at a flat angle. This guarantees that there are no reflections
on the touch screen so that it can be operated ergonomically.
The touch screen display is resistive. You must apply slight pressure to trigger the func-
tion of a particular button. Just slightly touching the display as with the capacitive touch
screen of a smartphone or tablet is not enough.
The lid is closed using the lid sealing button. In order to exert the ideal contact pressure
on the samples, turn the lid wheel clockwise until you can hear a click. This lowers the lid
until it touches the surface of the sample tubes. The integrated clutch mechanism en-
sures that the same contact pressure is effectively applied regardless of the sample ves-
sels’ height so that the conditions are reproducible.
You can use the USB port to export PCR protocols and run log files and save them onto a
USB flash drive. This allows exchanging PCR protocols between instruments or saving
run log files for documentation purposes to a PC with ease.
The device has an automatic restart function. In case of a power failure during a PCR
run, the device will resume running as soon as the power supply is reestablished.
In the event of a prolonged power failure (≥30 min) the Freeze program will start auto-
matically: The device will then cool down the sample block to 4 °C. You can then decide
whether to repeat the run or to discard the samples.
