UTOOLIGO is a flexible and intuitive full-automatic oligonucleotide synthesizer, which can be used for 1 μ The rapid synthesis of mol-50mmol nucleic acid sample is suitable for clinical research, medical development and the synthesis of molecular diagnostic probes.
AUTOOLIGO comes in four models:
● AUTOOLIGO, synthesis capacity 10~100 μ mol
● AUTOOLIGO100, synthetic capacity 50 μ mol~9mmol
● AUTOOLIGO150, synthesis capacity 150 μ mol~12 mmol
● AUTOOLIGO600, synthesis capacity 1mmol-50mmol
Unique AutoOligo adopts a high-precision metering pump drive system, which is compatible with reagents for nucleic acid synthesis. The adoption of flow solid phase column synthesis technology can significantly reduce reagent consumption, ensure the accurate control of reaction speed and contact time, and at the same time, the synthesis efficiency is higher, facilitating linear amplification, so as to obtain cost-effective and high-quality synthesis results.
AUTOOLIGO can use up to 14 kinds of monomers at the same time, and continuously and automatically perform the synthesis process on 1 or 3 or 8 columns.
The CD System workstation has a powerful data management system to provide you with a complete and reliable nucleic acid synthesis method development platform.
● High precision metering pump, flow path resistant to organic reagents;
● Multiple column positions are optional;
● High degree of automation and low reagent consumption;
● Monomer solution recycling;
