Illumina is an American life science tools and integrated systems manufacturer that specializes in DNA sequencing and array-based solutions for genetic and genomic analysis. It was incorporated in California in April 1998 by David Walt, Larry Bock, John Stuelpnagel, Anthony Czarnik, and Mark Chee to develop and commercialize BeadArray technology licensed from Tufts University. The company is headquartered in San Diego, United States, and trades publicly on Nasdaq under the ticker ILMN with no parent company. Its instruments perform DNA sequencing, the reading of the order of bases in a genome, and they are the platforms behind most short-read genomic analysis published today. The product range covers benchtop sequencers, high-throughput systems, microarray scanners and the reagents and consumables that run them. On Questpair, these systems are listed as used units from verified suppliers and distributors.
Sequencing is the field this equipment serves. The instruments are built for whole-genome sequencing, targeted resequencing and exome work, and they anchor laboratories doing genomics, molecular diagnostics and cell culture research across clinical and academic settings. The array platforms support genotyping and gene expression studies, and the whole family feeds into molecular biology workflows from library preparation through to variant calling. The DRAGEN and Illumina Connected Analytics software lines turn raw reads into analysed data, so the hardware rarely stands alone.
Illumina sequencer and array product lines
The sequencing instruments split by throughput. The iSeq and MiniSeq are the smallest, built for targeted panels and amplicon runs. The MiSeq is the established benchtop system for small genomes, microbiology and targeted resequencing. The NextSeq raises output to exomes and larger panels, and the NovaSeq and HiSeq are the high-throughput platforms for whole-genome sequencing and population-scale genomics. Alongside these sit the array products: the iScan microarray scanner and the VeriSeq and TruSight application kits for specific clinical and oncology panels, with COVIDSeq a dedicated assay line. Each line has its own flow cells, library preparation kits and sequencing reagents, so a buyer matching a used instrument to an application should check which chemistry the model supports.
Which Illumina systems are listed on Questpair?
The Questpair catalogue holds 205 Illumina listings from 9 verified suppliers and distributors across 5 countries. Prices run from EUR 139 to EUR 301.311, the distance between a benchtop sequencer and a high-throughput system, with the average listing at EUR 18.226. Every unit is listed as used, and 100 percent of the listings are used. The spread reflects the throughput tiers in the range, so a buyer can match a listing to the intended run rather than to the brand alone. Where a warranty is needed it is arranged in consultation for the specific listing, and parts can be sourced via Questpair. For manuals or documentation a buyer can contact Questpair, where specialists respond within the hour.
Questpair review of Illumina
Our take based on listings data and supplier feedback
Illumina occupies an unusual position in the lab equipment market: it is the dominant maker of short-read DNA sequencing instruments, and much of the published genomic literature of the last fifteen years rests on data generated on its platforms. That matters for a buyer evaluating a used listing, because an Illumina sequencer is not a standalone box but the centre of a workflow that includes flow cells, library preparation kits and sequencing reagents, most of which remain available for the current instrument lines. Three things separate these systems on the Questpair catalogue, and each is worth weighing against the specific listing rather than the brand as a whole.
The first is throughput tier. The product range splits cleanly by output. The iSeq and MiniSeq sit at the low end, suited to small targeted panels and amplicon work. The MiSeq handles small genomes, 16S microbiology and targeted resequencing. The NextSeq steps up to exomes and larger panels, and the NovaSeq and HiSeq cover whole-genome sequencing and population-scale projects. A used listing is only a good fit if its tier matches the intended run, and the price difference between tiers is large. On Questpair that spread is visible directly: listed prices range from EUR 139 to EUR 301.311, which is the gap between a benchtop sequencer and a high-throughput system.
The second is condition and what it means for a consumables-driven instrument. Every Illumina unit on the Questpair catalogue is listed as used, and 100 percent of the listings are used. For a sequencer this is less of a concern than it sounds, because the optics and fluidics are built for continuous operation and the consumable flow cell is replaced every run. The question for a used unit is less about wear and more about which chemistry version the instrument supports and whether the kits for that version are still produced. A buyer should check the model generation against the kit availability for the planned application.
The third is total workflow cost. The sequencer price is only part of the picture, since reagents, flow cells and library preparation kits recur with every run. Across the catalogue the average listing sits at EUR 18.226, but the instrument is the one-time cost against an ongoing consumable spend that often exceeds it over an instrument's life. For a lab moving into genomics, molecular diagnostics or proteomics-adjacent work, the used instrument lowers the entry cost while the running cost stays the same as new. Where a buyer has to weigh a used unit against a new one, the clearest difference is price, and warranty on a Questpair listing is arranged in consultation for that specific listing.
