Tab 04 / Freedom® Evo NGS workstation

There are so many things that you have to get right to create high quality libraries for reliable next generation sequencing, so why have unnecessary complexity in your liquid handling?

Automation of NGS sample preparation on the Freedom EVO NGS workstation increases throughput and reproducibility, guiding the user through each step of protocol selection and worktable set-up with the TouchTools™ operator interface.

Freedom EVO NGS workstation

The Freedom EVO NGS workstation is equipped with innovative air displacement pipetting technology, using eight pipetting channels (1) to allow precise pipetting from 1,000 µl down to 0.5 µl. The workstation includes three Inheco CPAC devices (2) to keep reagents cool and provide optimal conditions for the enzymatic steps, an Inheco Thermoshake heated shaker (3), a 96-position Alpaqua 96S Super Magnet Plate magnetic plate separator (4) and a RoMa Arm (5) for efficient bead clean-up. In addition, the compact worktable provides storage space for up to 12 tip boxes (6), allowing longer unattended runs.

Precision: The Freedom EVO’s precision automation ensures the reproducibility necessary for high quality results, with a range of qualified sequencing-verified protocols available.
Flexibility: Don’t be constrained by batching requirements. Whether you need to process 6, 13, 19, 40 or even 96 samples, only run what you need, saving on reagents.
Simplicity: You don’t need to be an automation expert. With the simple touchscreen interface, you can get started right away, set up your runs quickly and be confident in your workflows.

NGS Sample preparation Freedom EVO with Touchtools

TouchTools operator interface

The TouchTools application starter screen lets the operator select the desired protocol with the touch of a button. Step-by-step user instructions help to avoid potential errors during worktable set-up to ensure the correct initial conditions. A selection confirmation screen then provides a summary as a final check before starting the run, making it easy for anyone in the lab to use the instrument.

Installation and support

The Freedom EVO NGS workstation is supplied with one of the standard protocols available at the time of installation, including water testing and user training. Additional protocols can be installed at any time.

Tecan Journal Articles

The Leiden University Medical Center has integrated the Freedom EVO® NGS workstation into its molecular diagnostic testing and clinical research workflows. Taking advantage of this preconfigured solution, the center was quickly able to commission the platform for routine testing, while still having the flexibility to develop new protocols and conduct research studies.

The University of North Carolina (UNC) has automated its major sample preparation protocols for next generation sequencing on a Freedom EVO® workstation, enabling more efficient processing.

The GeT genomics facility near Toulouse has been developing a series of automated NGS protocols in collaboration with Tecan – including Illumina’s TruSeq® DNA and RNA kits, as well as Bioo Scientific’s NEXTflex™ PCR-Free Modules – on two Freedom EVO® workstations, helping to improve throughput and reliability for a wide range of projects.

NGS library quantification is a crucial step for a successful sequencing run. Accurately determining the number of sequenceable molecules is highly significant for new high capacity sequencers, such as the NovaSeq system.

Tecan NuQuant technology

Tecan NuQuant technology

Tecan NuQuant® is a novel library quantification method that accurately measures molar library concentration without the need for separate fragment size analysis. This proprietary method uses a fluorescent label that is incorporated into the library molecules during library preparation. NuQuant is independent of library size, allowing library molarity to be directly measured using fluorometers, such as the Infinite F Nano+ multimode reader.

Integrated library QC in less than six minutes

NuQuant library quantification on the Infinite F Nano+ plate reader eliminates the need for additional manual qPCR or capillary electrophoresis steps, saving significant time, resources and valuable library material.

After final purification of the DNA libraries in a 96-well plate on the Fluent ® Automation Workstation, the fluorescence of the libraries and standards is measured on the Infinite plate reader. The molarity determined for each library can then be used for balanced pooling and subsequent sequencing on Illumina instruments.

Other quantification assays

Other quantification assays

Reader integration for quantification

DNA quantification can be achieved by measuring an aliquot with a fluorescent dye, such as PicoGreen® or QuantiFluor™, or by measuring the absorbance of the entire DNA sample. DNA quantification and normalization workflows typically include the following steps

  • Set-up of quantification assay
  • Determination of the DNA concentration in a reader
  • Calculation of a dilution scheme to achieve the target concentration for each well
  • Dilution of the DNA samples to the desired concentration.
