Nucleic Acid Extraction Workstation, OPENTRONS, USA

Nucleic Acid Extraction Workstation

Get everything you need for nucleic acid extraction and get started right away. Easy – and affordable – automated cleanups.


Nucleic acid extraction using SPRI (solid-phase reversible immobilization) magnetic beads are one of the most common and painstaking processes done by modern molecular biology labs.

Anytime a PCR product is used in sensitive downstream processes like gene assembly or next-generation sequencing (NGS), labs must go through multiple, time- and labor-intensive bead washing steps. The Opentrons Nucleic Acid Extraction Workstation is designed to automate your bead cleanups for you.

This workstation includes everything you need to start automating SPRI bead cleanups in your lab: the robot with magnetic module, correct labware, beads from Omega Bio-tek, and a validated protocol free to customize and download.

This workflow can be used for the following applications:

  • PCR Product Purification
  • NGS Library Clean-up
  • Any other bead-based size selection


  • Accuracy: 15% at 1uL

  • Precision: 5% at 1uL

  • Throughput: Fast fill a 96-well plate in 22 seconds


  • Supports Ethernet or USB connection (external dongle provided)

  • 4 USB ports available to support connection to multiple modules

  • Easy access to electronics via external PCBA enclosure

  • LED indicator provide users feedback, diagnosis & troubleshooting aid on instrument power state, system processing, ethernet, and network connectivity

User Friendly

  • Self-serve unboxing and installation

  • Reagent and bead system agnostic

  • Plug-and-play setup with access to protocol libraries to enable immediate assay implementation

  • Easily integrates to your existing instruments

  • Compatible with ANSI/SBS compliant or automation friendly tubes, microplates, deep-well plates, reservoirs and adapters

This application has been fully tested and scientifically validated in our lab with reagent partner Omega Bio-Tek. We recommend you use the Omega Bio-Tek Total-Pure NGS kit for this application. If you would like to use another kit, the OT-2 supports various kits for nucleic acid extraction.


This application has been verified with the Opentrons Cleanup Labware Bundle, which includes plates for the magnetic module, reagent reservoirs, and tubes. If you have different labware requirements, reach out to our sales team to discuss modification of this protocol to fit your needs.


This application uses the p300 single-channel or 8-channel pipettes for the OT-2 robot. If you have different volume requirements, contact our sales team to ask about protocol modification.
