Give your laboratory automation more freedom:
compatibilityExtensive API compatible with Design of Experiments programs, including AI drivers |
flexibilitySelf-replaceable modular pipettes, plate grippers and upper hardware |
opennessCompletely open source software and firmware, widely compatible with mainstream reagents with mainstream reagents and laboratory consumables |
accessibilityMultiple workstation configurations available; easy access to shared protocol resources |
Powerful automation capabilities for your applications

NGS Library Preparation
With the Flex NGS Workstation, you can automate NGS library preparation on demand, increasing efficiency, reducing errors, and saving hands-on time. You can use any popular reagent on the market to automate all pre-sequencing workflows, including fragmentation- and tagging-based library preparation.
PCR
With the Flex PCR Workstation, you can fully automate your PCR setup and thermal cycling workflow for up to 96 samples. Aliquot cooled reagents and samples into 96-well PCR plates, use the Flex clamp to load the PCR plate into the thermal cycler on the Flex bench, and run the PCR program of your choice.
Protein Purification
Using the Flex Magnetic Bead Protein Purification Workstation, you can automate small-scale protein purification and proteomics sample preparation, processing up to 96 samples at a time. The workstation is compatible with many of the most popular magnetic bead-based reagents on the market.
Nucleic acid extraction
Using the Flex Nucleic Acid Extraction Workstation, you can automate DNA/RNA isolation and purification. The workstation is equipped with a Flex ring magnet for magnetic bead separation and an Opentrons thermal shaker for sample lysis and magnetic bead resuspension.
Reagent packaging
With the Flex Dispensing Station, you can automatically dispense samples or reagents from 2, 12, or 15 mL centrifuge tubes into 96-well plates. This workstation automates many of the laboratory's most repetitive and time-consuming basic liquid dispensing tasks.

API compatibility
Interface with any product that has an API
Opentrons software is open source and users can adapt the software as needed to interface with other products. While all integrations are possible, they all require custom code work, i.e. most customers will need to write custom libraries and install packages that don't come with the robot.
