Real-time optical density using IR light

Our built-in optical density sensors record the state of your culture every five seconds. The sensors can be oriented to record scatter (135°, 90°, or 45°) or transmission.

Also included is a reference photodiode, to control for variations in LED luminosity.

Mixing and agitation

A magnetic stir bar provides agitation and mixing. RPMs range from 50 - 1000 RPM and are controlled via a feedback loop.

Web-based interface for controlling bioreactors

The Pioreactor comes with an intuitive browser-based interface. All the Pioreactors in your cluster are controlled from a single interface.

Real-time growth rates

Using biologically-inspired algorithms, the Pioreactor calculates a real-time growth rate of the culture after every optical density measurement - including during and after pumping.

Control how and when liquid is handled

Attaching peristaltic pumps to the Pioreactor allows for controlled and measured dosing and removal of media. The vial comes with four inlets/outlets that can be used for doing, sampling and air flow - each with a male luer lock connector.

Pioreactor has common modes of dosing operations like turbidostat, chemostat, morbidostat, fed-batch, but can also be programmed for more specific needs.

Control up to four individual LEDs

Up to four 5mm LED can be used and then controlled programmatically with the Pioreactor. This turns your bioreactor into a photo-bioreactor to grow photosynthetic microorganisms. LEDs can be programmed for day/night cycles, or any specific behaviour you need!

Heating and thermoregulation

The Pioreactor has built-in heating and temperature sensors to stabilize the temperature of the culture, from ambient temp to ~(ambient temp + 20℃). Like the LEDs and dosing, the heating can be manually and automatically controlled.

Data exports to CSV

Almost every data point and system change is logged and recorded in an onboard SQL database. All datasets are easily exportable to CSV format from the interface. 

The Pioreactor exposes a real-time event stream for other software to listen to as well.

Built-in stirring calibration and pumping calibration

We think calibration should be automated. Whenever possible, we have automated calibration, so you don't have to spend time thinking about it.

Backup data between Pioreactors

When more than one Pioreactor is in your cluster, data is backed up between Pioreactors to minimize chances of data loss. 

Plugins can be installed to back up data into a private cloud as well.

Culture volume

The total volume of the bioreactor is 20ml, and the working volume is 15ml.

Programmable bioreactors at your fingertips

Design and implement your own bioreactor automations using the Pioreactor's API.

Use feedback loops to respond to how your cultures are progressing, set up alerts to other systems, or implement new machine learning models. Our source code is open source, too!

Add your own sensors

The Pioreactor hardware has a StemmaQT / Qwiic connector that allows for third party sensors to be easily integerated into the Pioreactor system.

For example, this is Adafruit's SCD-40 sensor: a true CO₂, temperature, and humidity sensor that can be used in a CO₂ incubator with the Pioreactor. The Pioreactor can read from this sensor using the StemmaQT / Qwiic connection.

Add additional Pioreactors to your cluster

Our software and web interface can scale to any number of Pioreactors: quickly add Pioreactors to expand to the needs of your experiments and control them in parallel.
