Quality scores* and run time†
NovaSeq X Series
| Flow Cell Type |
1.5B | 10B | 25B |
|---|---|---|---|
| Quality Scores | |||
| 2 × 50 bp | ≥ 90% of bases higher than Q30 | ||
| 2 × 100 bp | ≥ 85% of bases higher than Q30 | ||
| 2 × 150 bp | ≥ 85% of bases higher than Q30 | ||
| Run Time | |||
| 2 × 50 bp | ~17 hr | ~18 hr | ~25 hr |
| 2 × 100 bp | ~20 hr | ~22 hr | ~38 hr |
| 2 × 150 bp | ~23 hr | ~25 hr | ~48 hr |
* A quality score (Q-score) is a prediction of the probability of an error in base calling. The percentage of bases > Q30 is averaged across the entire run. Quality scores are based on NovaSeq X series 10B reagents using an Illumina PhiX control library. Performance may vary based on library type and quality, insert size, loading concentration, and other experimental factors.
† Run time includes automated cluster generation, sequencing, automated post-run wash, and base calling. Run times are based on Illumina PhiX control library at supported cluster densities. Performance may vary based on library type and quality, insert size, loading concentration, and other experimental factors.
How to maximize performance on the NovaSeq X Series
Follow the best practices outlined in this technical note to assess library quality, optimize loading concentration, and pool libraries to maximize performance on the NovaSeq X Series.
Estimated sample throughput for key applications*
NovaSeq X Series
| Flow cell type | 1.5B | 10B | 25B |
|---|---|---|---|
| Human genomes per flow cell | ~4 | ~24 | ~64 |
| Exomes per flow cell | ~41 | ~250 | ~750 |
| Transcriptomes per flow cell | ~30 | ~200 | ~520 |
*All sample throughputs are estimates per single flow cell run. Human genomes assumes > 120 Gb of data per sample to achieve 30× genome coverage. Exomes assumes ~8 Gb or ~40M reads per sample to achieve 100x coverage. Transcriptomes assumes ≥ 50M reads. Throughput may vary based on many factors including exome panel size, depth required, and library preparation kit used.

Innovation powers the NovaSeq X Series
Go on a virtual tour of the many innovations in the NovaSeq X Series and an overview of XLEAP-SBS chemistry. Learn about the integrated bioinformatics, reduced data footprint, lyophilized reagents, and other innovations.
Breakthrough technology innovations delivering a leap forward in sequencing
Powered by XLEAP-SBS chemistry
The NovaSeq X Series is powered by XLEAP-SBS chemistry, our fastest, highest quality, and most robust sequencing by synthesis (SBS) chemistry to date. Built upon the proven foundation of standard Illumina SBS chemistry, XLEAP-SBS chemistry delivers improved reagent stability with two-fold faster incorporation times.
Ultra-high density patterned flow cells
The NovaSeq X Series incorporates patterned flow cell technology to generate an ultra-high level of throughput for a broad range of sequencing applications. NovaSeq X patterned flow cells contain tens of billions of nanowells at fixed locations, a design that provides even spacing of sequencing clusters. This delivers significant increases in sequencing reads and total output of the system.
Streamlined, comprehensive informatics
The NovaSeq X and NovaSeq X Plus Systems are integrated with the DRAGEN secondary analysis Platform for ultra-rapid, accurate genomic data analysis. Run multiple secondary analysis pipelines in parallel, onboard or in the cloud. Run up to four simultaneous applications per flow cell in a single run.
Integrated DRAGEN ORA (original read archive) can perform lossless compression to reduce FASTQ file sizes by up to five-fold. This optimized genomics data compression enables faster data transfers and easier data management. The smaller data footprint also reduces storage and energy consumption costs.
More discoveries, more sustainably than ever
The NovaSeq X Series was purpose-built for improved sustainability. Innovations include lyophilized reagents that arrive at room temperature and a ~90% reduction in packaging waste for reagents. Plastic mass is reduced by over 50% and the buffer cartridge is made with a plant-based biopolymer.
The NovaSeq X Series achieves ultra-high-resolution imaging through higher numerical aperture, a custom CMOS sensor, and two-channel SBS with blue-green optics. The smaller wavelengths allow for tighter spacing between nanowells for up to 26 billion single reads on NovaSeq X Series 25B flow cells.
