Opentrons OT-2 — a compact robot for every budget

OT-2 is the first Opentrons robot. It fits on half a lab bench (63 × 57 × 66 cm, 48 kg) and offers 11 deck slots and single- and 8-channel P20, P300 and P1000 pipettes. It is compact and can be used for extraction, PCR setup and NGS libraries.

  • 1 and 8 channel heads
  • 11 Deck slots
  • 1–1,000 µl pipetting range
  • 48 kg Weight, half-bench footprint
About the robot

Affordable automation without compromising on quality

OT-2 is the first widely adopted Opentrons robot, on the market since 2018. Its compact format, simple operation and affordable price have made it a common choice for academic institutions, teaching, biotech start-ups and smaller projects. Its certifications cover CE, FCC, NRTL, CB and ISO 9001.

Compared with Flex, OT-2 is more modest. It has single- and 8-channel heads and can handle NGS library preparation in smaller batches, PCR setup, extraction, ELISA and other routine workflows.

Components

OT-2 hardware down to the last detail

Swappable pipettes

Two pipette mounts for swappable pipettes. Accuracy of ±15% at 1 µl and ±1.5% at 20 µl for the single-channel pipette. A 1–1,000 µl range without having to buy more expensive models.

1-channel P20, P300 and P1000

Three models with ranges of 1–20 µl, 20–300 µl and 100–1,000 µl. For master mixes, dilutions and routine pipetting from tubes.

8-channel P20 and P300

Two models with ranges of 1–20 µl and 20–300 µl. For column operations on a 96-well plate, which covers libraries of up to 96 samples per batch.

On-deck modules

Five module types that plug into deck slots and extend what the robot can do.

Thermocycler Module

PCR directly on the robot deck, without moving the plate off the instrument. Handles standard PCR protocols as well as library amplification.

Heater-Shaker Module

Heating and shaking in a single slot. For magnetic bead clean-ups, resuspension and incubations above room temperature.

Temperature Module

Temperature control from 4 °C to 95 °C for reagents and enzymatic reactions that need a stable temperature.

Magnetic Module

An active magnetic module for SPRI bead clean-ups (AMPure XP, KAPA Pure Beads). Compatible with most NGS protocols.

HEPA Filter Module

HEPA filtration over the deck. For workflows where a clean environment matters, such as single-cell methods and low DNA inputs.

Interface and control

OT-2 is simpler than Flex: it has no built-in display or gripper. Protocols run the same way, but they are started from an app on a computer.

Control via the Opentrons App

The robot is controlled with an app for Windows, macOS and Linux over USB or Wi-Fi. Protocol start, progress monitoring and alerts are all in one interface.

Manual XYZ calibration

When a new protocol is set up, pipette and tip-rack positions are calibrated manually in the app. It takes longer than on Flex, but the result is just as accurate.

Camera and audio

A built-in camera and microphone let you monitor a protocol run over the network, from the next room or from home.

NGS focus

OT-2 as a robot for smaller library batches

Even without a 96-channel head, OT-2 handles most library preparation protocols. The difference is that it processes the plate column by column rather than all at once. For smaller numbers of samples, that is sufficient.

The 8-channel pipette, on-deck thermocycler, heater-shaker and magnetic module cover the entire workflow: fragmentation, adapter ligation, amplification, SPRI bead clean-up and pooling.

Smaller sample batches

The 8-channel pipette processes a 96-well plate column by column. That is sufficient for pilot studies or smaller numbers of samples.

On-deck PCR

The thermocycler module enables PCR directly on the robot, so libraries are amplified without moving the plate to another instrument.

Bead clean-up

The magnetic module, heater-shaker and precise pipetting handle the magnetic bead clean-up steps automatically.

Accuracy at 1 µl

Accuracy of ±15% at 1 µl for the single-channel P20. Usable even for low-input libraries and limited samples.

Other applications beyond NGS

OT-2 handles more than NGS

PCR setup

PCR setup

Setup of standard PCR and qPCR, suitable for both teaching and research. Combined with the on-deck thermocycler, the entire reaction runs in the robot.

Nucleic acid extraction

Nucleic acid extraction

DNA and RNA isolation with the magnetic and temperature modules. Compatible with both Norgen and QIAGEN kits.

ELISA and proteomics

ELISA and proteomics

Automation of immunoassays, proteomic workflows and antibody work. Frequently used at academic institutions.

Software

Three paths to your own protocol

Protocol Designer

A graphical editor in the browser. You build a protocol from blocks, export it and run it via the Opentrons App, with no coding required. Sufficient for routine pipetting.

Protocol Library

An open library of ready-made protocols from Opentrons and its users: library preparation, extraction and PCR. Protocols can be reused and modified.

Python API

Full programmatic access for complex workflows. Multi-step protocols, dynamic branching and custom logic. This is where our application specialists work.

OT-2 or Flex

When to choose OT-2 and when Flex

OT-2 if…

You have a limited budget and process smaller numbers of samples. You need a compact instrument for a smaller lab and do not need a 96-channel head or a built-in display.

Flex if…

You need a 96-channel head that processes an entire plate in one step, automatic XYZ calibration, a gripper for moving plates and a built-in touchscreen.
