The DNBSEQ-T20×2 is designed to accommodate the most difficult sequencing circumstances. Using OMICS technology, global large-scale population genome studies and healthcare can be improved. The fully automated sequencer DNBSEQ-T20×2 processes six slides per run using robotic integration of all genetic sequencer components.

It addresses all high-throughput sequencing requirements in both academic and medical applications, including those for WGS, WGBS, stLFR, single-cell sequencing, stereo-seq, etc.

Model DNBSEQ-T20×2RS
Slide/ Run 6
Effective Reads/Slide* 35 B (PE100)
40 B (PE150)
Read lengths PE100


* The maximum number of effective reads are based on a specific standard library, and the actual application library will fluctuate depending on the sample type and library construction method.

Supported Read Lengths Data Output per run Data Quality Q30* Run Time per run**
PE100 ~42 Tb >85% ~60 h
PE150*** ~72 Tb >80% ~80 h


* The percentage of bases above Q30 is obtained by averaging metrics for runs using standard library. Actual performance is influenced by sample type, library quality and type, insert length among other factors.

** The run time includes DNB loading, sequencing, and generation of Cal. file. Cal. file is a binary file format generated by MGI sequencer basecall software.

*** PE150 will be released on Q3 2023.
