Biological Shakers Innova® 44/44R — Operating manual
48
The three-step program we have illustrated is designed to start incubating cultures at 37 °C and
hold that temperature for eight hours, shaking at 150 RPM. After eight hours, Step 2 engages,
increasing the temperature setpoint to 40 °C for a temperature induction, holding that
temperature for three hours and increasing the shaking speed to 225 RPM. After this interval, the
temperature will be cooled to 4 °C and held at that temperature for twelve hours; no shaking will
occur during this period, as the speed is set to 0 RPM.
Please note that temperature reductions, even at temperatures above ambient (going from 40 °C
to 30 °C, for example), require refrigeration to be effective.
To save the entire program:
1. Once all your steps are set, use the Control Knob to highlight Save at the bottom of the
screen, then click the Knob in. The field will flash.
2. Click the Knob in again to save the program. The display will read Process Running –
Saving Profile for a few seconds, then return to the main Programs (PROG) screen.
If you wish, you can set Programs 2, 3 and 4 and save them in the same manner.
9.5.4 Edit a program
Use the Edit function to open a program you have already created and saved, in order to modify
your settings following the same procedures.
9.5.5 Run a program
Use the Run fuction to turn a specific program on. Naturally, only one program can run at a time.
When you change the mode to Run, the screen will show the Run icon:

Hint!
When the last step of a program is completed, the Innova 44/44R will continue operating
according to the parameters of the final step programmed, until the user intervenes.
Hint!
If you wish the shaker contents to experience different conditions (e.g., a different shaking speed
or no shaking at all, and/or return to ambient temperature), set those parameters as the last step
in your program.
