The ÄKTA oligosynt™ oligonucleotide synthesizer is a compact, fully automated oligonucleotide synthesizer built for research and process development laboratories. The system supports a robust and easily scalable oligonucleotide synthesis process and transfer to larger oligonucleotide synthesizers with high yield and quality.
System benefits
- The broad synthesis scale and optimized hold-up volume combined with a small system footprint enable a broad and flexible use for research and development requirements.
- Flexible and easy method editing, and the interactive user interface offer ease of use and support scale-up requirements.
- Robust process control is supported by sensors measuring pressure, air, temperature, UV, and conductivity. Input from external modules is also possible.
The ÄKTA oligosynt’s open front ensures easy access to all modules and full ventilation. The flow path is optimized for achieving a low hold-up volume, limiting the dilution of expensive amidites and excessive use of reagents and solvents.
Modules included with the system include two high-precision pumps, a pressure monitor, two solvent valves, two amidite valves, a recirculation valve, a column valve, a waste valve, an I/O-box, a UV monitor, and a conductivity monitor.
Components of the oligonucleotide synthesis platform
Software
The ÄKTA oligosynt™ synthesizer is controlled by UNICORN™ software, which provides real-time control of the system. Basic methods for the desired target sequence can be created in minutes using pre-defined methods and the sequence editor. UNICORN™ software also supports evaluation of results. The method overview is transparent with limited use of macros.

Primer Support™ 5G solid support
The ÄKTA oligosynt™ synthesizer and compatible Cytiva columns are designed for use with Primer Support™ 5G polystyrene solid support. This high-loaded solid support for DNA or RNA oligonucleotide synthesis is available using standard DNA and RNA bases as well as with UnyLinker™ solid support as a starting point, making the solid support more flexible for DNA synthesis.
