Sterility
Full polycarbonate enclosure designed to limit exposure. The Opentrons Flex is not a sterile environment. An optional HEPA/UV accessory is in development.
Deck Slots
12 main ANSI/SLAS-format deck slots (working area, accessible to pipettes and gripper) 4 additional slots for staging tips and labware (staging area, accessible to gripper only)
Ros Support

Return Policy
60 day return policy
Rear Clearance
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.
Coding Required
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.
Crash Detection
Crashes will be detected by the Opentrons Flex by comparing the actual vs. intended move of the embedded motors.
Pipette Volumes
Flex 1-Channel Pipettes: 1–50 µL, 5–1000 µL Flex 8-Channel Pipettes: 1–50 µL, 5–1000 µL Flex 96-Channel Pipette: 1-200 µL, 5–1000 µL
Fleet Management
Yes
Api Compatibility
Opentrons software is open-source and users can make adjustments to the software as needed to interface with other products. While all integrations are possible, they all require custom code work: most customers will need to write custom libraries and install software packages that are not shipped with the robot.
Service Offerings
The Opentrons Flex requires on-site installation. We also offer both remote and on-site services solutions, as well as annual preventative maintenance.
Tip Compatibility
Use Opentrons Flex Tips and Opentrons Flex Filter Tips
Ot 2 Compatibility
No, Opentrons’ OT-2 pipettes will not be compatible with the Opentrons Flex. The Opentrons Flex is intended for use with our Flex Pipettes.
Power Adapter Input
100–240 VAC, 50/60 Hz, 4.0 A/115 VAC, 2.0 A/230 VAC
Computer Requirement
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.
Gantry Motors Upgrade
Yes, we are still using stepper motors with linear encoders. This enables us to track the steps of the motor and handle errors with positioning.
Labware Compatibility
Use common labware already in our Labware Library, or add your own. If your labware fits on the Opentrons Flex but is not in the Labware Library, it can be added by you using our Labware Creator, or by our team.
Remote Protocol Start
Yes, this can be achieved through the Opentrons app. You will need to be connected to a computer that is on the same WiFi or wired network as the liquid handler.
Side Panels Removable
Yes, the Opentrons Flex’s side windows and front door are removable.
Software Requirements
Windows 10 or later, macOS 10.10 or later, Ubuntu 12.04 or later.
Operating Temp Humidity
Recommended 20–25 °C Recommended 40–60% RH
Smart Sensors Calibration
This is not an optical process. The robot uses capacitance sensors and a calibration probe (shipped with Flex pipettes) to perform automated calibration.
Accuracy 1 Channel Pipette
8% at 1 µL
Independent Volume Control
The Opentrons Flex 8-channel and 96-channel pipettes will aspirate and dispense the same volume with all channels at the same time. Volume is not independently controlled across channels.
Protocols Saved On Display
Users can save up to 8 protocols to the Opentrons Flex display.
Precision 1 Channel Pipette
7% at 1 µL
Irregular Labware Compatibility
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.
Multiple Computers For One Robot
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.
