Illumina NextSeq 550

This is a used Illumina NextSeq 550, the successor to the NextSeq 500 platform that added an onboard array scanning capability alongside its core sequencing function, giving labs a single instrument that can handle both genotyping array reads and next generation sequencing runs. It uses the same two channel chemistry and high resolution optics as its predecessor, delivering flexible read lengths and output scaling across its supported flow cell types. The added array scanning mode makes it attractive to labs that run both microarray based and sequencing based genomic assays. The unit offered here comes from a working laboratory setting and is being sold as used equipment in good functional condition for its age. It includes the fluidics cartridge dock, imaging module, and internal control computer, and it completes its standard power on diagnostics. Buyers should plan to run a qualification sequencing pass with new reagents after installation, which is standard practice when bringing any secondhand sequencer back online. The NextSeq 550 is well suited to clinical research groups, genomics core facilities, and biotech labs running RNA sequencing, targeted panels, whole genome sequencing at lower coverage, or microarray scanning for SNP genotyping studies. Its dual mode operation and moderate throughput make it a flexible addition for labs that want array and sequencing capability without operating two separate machines.
