Available in both 8- and 24-capillary configurations, SeqStudio Flex Series genetic analyzers are designed with scientists in mind.

Sample loading flexibility

Four-plate capacity, continuous plate loading, and urgent sample reprioritization provide both the largest mid-throughput capacity and complete scheduling flexibility, translating into extra time in your day.

Ease of use

Easier capillary array installation, streamlined one-button start up, autocalibration, and an onboard learning center offer users of any skill level greater usability and streamlined training whether they work in a single- or multi-user environment.

Standalone instrument

An integrated touchscreen computer with intuitive software and walk-through wizards for simplfied sample mapping, plate linking, and run setup. 

Remote setup, monitoring, and data transfer

Our Thermo Connect Platform provides enhanced flexibility and simplified collaboration by allowing users to stay connected to their instrument and data, remotely and safely, from anywhere.

Remote troubleshooting

Smart Help and Remote Support capabilities reduce instrument downtime and resolve up to 70% of issues without a service visit using immersive, real-time audio/video collaboration tools and push-button support requests.

Advanced communications and connectivity

Integrating the communication technologies of today, such as voice commands and a wide array of connectivity options, to propel laboratory efficiencies of tomorrow.


SeqStudio Flex genetic analyzers deliver high-level Sanger sequencing and fragment analysis performance using capillary electrophoresis to support a diverse range of applications, including:

Targeted sequencing

NGS confirmation

Cell line authentication

Minor variant finding

Gene editing confirmation

Multiplexed PCR

Microbe or virus identification

DNA methylation analysis

SNP genotyping

Microsatellite instability (MSI) analysis

dsDNA quality control

Plasmid sequencing

Featured applications

Multiplexed PCR analysis

While quantitative PCR is the mainstay for rapid and concurrent analysis of several genomic sequences, it can be limited by the number of unique fluorophores, and therefore, the number of genomic targets that can be queried. In situations where a high multiplexing capability is desired, standard PCR coupled with fragment analysis by capillary electrophoresis offers a versatile solution to detect multiple targets in a single reaction as it separates amplicons based on both size and fluor in a single capillary allowing a very high degree of multiplexing.


It is often necessary to run a quality check (QC) on a starting pool of double-stranded DNA (dsDNA) before initiating genomic analysis or continuing to the next step. For example, DNA extracted from FFPE-preserved tissue may be fragmented and too small to provide useful information, so it’s useful to know the overall size before proceeding.

Optimized end-to-end workflow

Thermo Fisher Scientific is committed to helping you improve data quality and drive laboratory efficiency for all your Sanger sequencing and fragment analysis applications, by providing everything you need for successful capillary electrophoresis (CE) separations from sample preparation through data analysis. We focus on quality and providing fully validated workflow solutions so that you can focus on your research.
