Temperature non-uniformity test
Configuring the
GeneAmp
®
9700
1. Power on the thermal cycler. The Main menu opens. For best results, allow the
thermal cycler 15 to 30 minutes to warm up to ambient temperature before
performing the test.
2. Press
F4
(Util).
The Utilities screen opens.
3. Press
F1
(Diag). The Diagnostics screen opens.
4. Press
F3
(TmpVer). The Temperature Verification screen opens.
5. Press
F2
(TNU).
The thermal cycler automatically starts to configure the temperature non-
uniformity test, with the cover setpoint of 35 °C and the sample starting with the
setpoint of 37 °C. It may take several minutes for the system to stabilize at the
cover and sample setpoint temperatures. After the system is configured, the
TNU Performance screen opens.
Running the test
The temperature non-uniformity test uses the 0.2-mL probe assembly to test the
temperature uniformity of 8 different wells in the sample block.
Note:
Press
F5
(Cancel) if you want to exit the test.
To run the temperature non-uniformity test:
1. Place the probe into the indicated well, then press
F1
(Run). The temperature
non-uniformity test for the setpoint temperature of 94 °C starts, and the TNU
Performance screen opens with the setpoint value displayed.
Note:
The sample block increases from 37 °C to 94 °C. The sample block must
be at 94 °C ±1.0 °C. It may take several minutes for the GeneAmp
®
9700
thermal cycler to stabilize at the setpoint temperature.
