6.0 Getting Started
6.1 Unpacking
Open the Labnet MultiGene™ OptiMax thermal cycler package, and confirm that all items listed below are included:
Labnet MultiGene OptiMax thermal cycler unit
Electric fuses (7A and 3.15A)
AC power cord
Instruction manual
If there are any items missing, damaged, or incorrect items, please contact your distributor or sales representative immediately.
NOTE: Use 7A fuse in power source 100-120, 50/60Hz countries, while 3.15A fuse is for power source 200-220V, 50/60Hz countries.
6.2 Initial Operation
Place the machine on a steady, flat table. Please keep the machine at least 30cm from the wall or other machine. Check the power
source is compatible with your machine’s fuse rating input. Connect the power cord to the power socket in the rear of the machine.
Press the Power On/Off switch to turn on the machine. The screen will show the software version for 10 seconds, and then will enter
the User Folder screen. Pressing any key will go to the User Folder screen immediately.
6.3 Heated Lid
The heated lid heats the air in the upper part of the sample vessels at a higher temperature than the reaction mixture. This prevents
condensation of the evaporated water vapor on the vessel walls, keeping the concentration unchanged during the heating and cooling
cycles. The top also places pressure on the caps of tubes and film on titer plates to prevent vapor loss and cross-contamination of
samples.
NOTES:
If the thermal cycler is started cold, approximately 2 to 3 minutes will be required before the heated lid is at operating temperature.
To avoid heat dissipation, the heated lid should be closed and tightened during a protocol run. Keeping the heated lid open during a
protocol run might cause HEATER ERROR, because the heated lid fails to reach the set temperature.
To evaporate the condensation water inside the sample block, and to avoid HEATER ERROR, users should turn off the Lid
Temperature under the SYSTEM mode before heating the sample block and keeping the lid open.

Instruction Manual | 5
6.4 Lid Opening/Closing
There are two ways to open the lid: 1) Slide the lid to the rear. This method is recommended for common operations and to prevent
the skin burning from the heated lid. 2) Lift up the lid. This method is used to clean up the heating plate of the lid.
Rotate the lid knob clockwise to lower down the heating plate and press down on the cap of the tubes, tighten until you feel
resistance. This adjustment will provide better contact between the tube or plates and the block for better performance. Rotate the lid
counterclockwise (Figure 4) until the lid opens. Only when the lid opens, the users can slide the lid to the rear (Figure 5). To lift up the
lid for the heating plate cleaning (Figures 6-8).

6.7 Loading the Reaction Vessel
For the optimal performance of the MultiGene thermal cycler, we recommend Labnet tubes and plates. The recommended sample
volume for 0.2 mL tubes or 96-well microplates is 5-100 µL. If using the heated lid with full skirted 96-well microplates it is highly
recommended to use a silicone compression mat.
NOTE: To avoid deformation of the sample tubes or strips, it’s important to load at least one tube in each of the four corners and at
least four tubes in the center of the block, as this will distribute the pressure evenly throughout the surface.
7.0 User Folder Management

9.4.2 Incremental/Decremental Temperature and Time Settings
To increase or decrease the dwell time or temperature after each repeat you must have more than one cycle repeat (i.e., 55°C and a
dwell time 40 seconds, you could decrement the second step by 5 seconds. The second step would be 55°C and a dwell time of 35
seconds).
1. Place the cursor at the Temperature or Time values. Press F3:INCRE.
2. Select increment/decremental values. The screen will ask to input the increment values. Press F3 + or F4 to choose increment or
decrement.
3. Enter your desired values, and press ENTER. The graph will show the increment/decrement values.
4. To accept the values, press F1:ACCEPT. Or, to re-enter the values, press F2:CLEAR.
To remove the Incremental/Decremental Temperature and Time settings, place the cursor in the temperature segment with
Incremental/Decremental Temperature and Time values. Press F2:CLEAR to clear the values. Pressing F1:ACCEPT will remove the
incremental/Decremental Temperature setting and its symbol.
Temperature Increment
Max. Temperature incremental value: ± 9.9°C
Max. Time incremental value (minute:second): ± 9:59
NOTES:
Temperature limits 4.0°C to 99.9°C. DO NOT exceed.
Only Multi-cycle segments will have incremental/decremental time or temperature function.
