Dosing and LED updates


You can run the pumps from the Pioreactor UI. These are NOT automations, but rather simple commands to use to set up an experiment, or perform cleaning.


Under the Dosing tab, you activate the media pump or the alt-media pump and concurrently the waste pump. This is called cycling. By running the waste pump simultaneously, the vial will avoids being overflowed. You can cycle for a set duration of time.

Specific control of pumps

Under the Dosing tab, you can also run specific pumps (media, waste, and alt-media) for specific durations, volumes (if calibrated), or continuously. The latter will run until the Stop button is pressed.


Careful not to overflow your vial! The vial can hold 20ml, but stay well below this.

Adjustments from manual changes

Sometimes you may want to add or remove liquid from the vial manually. These changes can be recorded by using the Manual adjustments form under the Dosing tab. These do not run the pumps, but will log the adjustments. This is useful for recording adjustments into the database, and keeping metrics accurate.


Under the LED tab, you can update specific intensities of the LEDs.
