Opentrons Flex Robot

The future of lab automation is here.

Opentrons Flex is a liquid-handling robot designed for high throughput and complex workflows. The Flex robot is the base of a modular system that includes pipettes, a labware gripper, on-deck modules, and labware — all of which you can swap out yourself. Flex is designed with a touchscreen so you can work with it directly at the lab bench, or you can control it from across your lab with the Opentrons App or our open-source APIs.

Purchase of Opentrons’ On-Site Installation service offering is required. Prices listed here are valid in the US and select other territories. Please get in touch with your local team for pricing for your territory.

Easily swap pipettes

Reliable liquid transfers from 1–1000 µL with our swappable 1-, 8-, and 96-channel pipettes.

Touchscreen for easy protocol setup

Select and run protocols directly from the lab bench using the touchscreen. It also guides you through deck setup and automated calibration.

Gripper extends walkaway time

The Flex Gripper can move plates and tip racks across the deck or on or off modules, maximizing throughput and walkaway time.

Modules to fit your workflow

Opentrons modules work seamlessly with our robots and software, and can be easily swapped out yourself. Choose from on-deck Thermocycler, Heater-Shaker, Temperature and Magnetic Block.

You do not need to know how to code to use the Opentrons Flex platform. Protocols can be created using Opentrons’ plug-and-play protocol design tools. We also have an Applications Engineering team that can build custom protocols for you.

The Opentrons Flex requires on-site installation. We also offer both remote and on-site services solutions, as well as annual preventative maintenance.

You can find more information on Opentrons’ service offerings here.

Yes. Just like the OT-2, the Flex has full capability to accept custom or irregular labware. Our custom labware creation tools can be used to help create the compatible labware definitions that are required to use irregular labware with our software.

Users do not need a computer connected to the Opentrons Flex to run a protocol. Users will need to build the protocol on a computer and upload it to the Flex. Once uploaded, the protocol can be ran solely off the display.

No, Opentrons’ OT-2 pipettes will not be compatible with the Opentrons Flex. The Opentrons Flex is intended for use with our Flex Pipettes.

Yes, the Opentrons Flex’s side windows and front door are removable.

Crashes will be detected by the Opentrons Flex by comparing the actual vs. intended move of the embedded motors.

For example, If the robot expected 2 motor rotations, but only 1 rotation is completed due to a crash(which stops the motors from moving), then the robot would detect a discrepancy between intended move and actual. This would then throw an error and let you know you need to recalibrate.

You can use one computer running the Opentrons App to connect to multiple robots. This is true for both the Opentrons Flex and OT-2 robots.

Users can save up to 8 protocols to the Opentrons Flex display.

20 cm (8 in) of side and back clearance for cables, USB connections, and to dissipate exhaust from instruments like the Thermocycler or Temperature Module.
