The easiest method to save time in the lab. The OT-2 pipetting robot makes it easy for users to automate various fundamental liquid handling operations, including sample pooling, cherry picking, serial dilution, tube and microplate filling, and normalization. Users can design their own protocols, ask the Applications Engineering team to build one, or select from a variety of tested protocols in the Protocol Library.

PCR Setup

Another widely used automation application, particularly for users preparing many samples. To mix samples and PCR mastermix in the reaction plate placed in the thermocycler or qPCR equipment, users can utilize the OT-2 pipetting robot.

Protein Purification

API compatibility Interfaces with any product that has an API
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 i.e. most customers will need to write custom libraries and install software packages that are not shipped with the robot.
Interface Windows 10, macOS 10.10 or later, Ubuntu 12.04 or later.

Tip compatibility Use Opentrons Tips and Opentrons Filter Tips
Opentrons guarantees the performance of Opentrons Tips specifically designed for the OT-2. The OT-2 was designed to accommodate all universal bore tip types, but tip quality and dimensions can vary significantly, so third-party tip Opentrons cannot guarantee performance.
Labware compatibility Use common labware already in our Labware Library, or add your own. If your labware fits on the OT-2 but is not in the Labware Library, you can add it using our Labware Creator or our team.
Warranty One-year warranty against manufacturer defects
Stress tested to last a minimum of 3 years of full-time use

Choose the Hardware and Pipettes

  • 11 deck slots, plus trash, and space for two swappable, single and 8-Channel pipettes
  • Magnetic, Temp, Thermocycler, Heater-Shaker, and HEPA Filter modules available

Use the Existing Labware and Reagents

  • Reagent and consumables agnostic
  • Compatible with any ANSI/SLAS-compliant labware

Choose the Right Protocol Method

A protocol is the code that directs the robot through the experiment. They have developed many methods for creating a protocol accessible to everyone, from automation novices to seasoned Python coders.

Custom Protocol

  • Ideal for users who want a quick, sophisticated, or unique protocol
    • Have a protocol designed specifically for the experiment created by the specialists

Protocol Library

  • Ideal for new users seeking to acquire experience
    • Look for open-source protocols that are thoroughly documented

Protocol Designer

  • Ideal for users who wish to develop a novel protocol without having to code
    • Create new protocols using the user-friendly drag-and-drop interface

Python Protocol API

  • Ideal for those who know Python
    • Using the open-source Python Protocol API, users can develop their own protocols.
