The CustomArray B3™ Synthesizer offers researchers the ability to fabricate low-, medium-, and high-density microarrays. The platform is easy to use and enables researchers to synthesize novel applications, build from the CustomArray list of pre-designed microarrays, or customize your own microarray designs.

Microarray Throughput

Fabricates one to 32 microarrays in less than 24 hours

Ease of Use

Automated to minimize operator supervision (e.g. runs overnight)

In-situ Synthesis - Free of spotting or printing

Oligonucleotides no longer need to be ordered or held in inventory – reducing costs of ownership

Arrays can be read on chip readers using either single-color or two-color fluorescence or using electrochemical detection via readout on the ElectraSense chip reader (reads 12k chip in 20-45 seconds)

Cost Efficiency

Arrays are re-usable, typically up to three times after initial usage


Produces commercial-grade high quality microarrays

High oligonucleotide coupling efficiencies

On-board quality control systems

Established quality-control procedures

Open Platform

Complete freedom to develop new and novel applications


Manage production schedules and supply

Maintain control of proprietary probe designs

Change designs to meet updates to sequence databases (especially useful for miRNA detection arrays)


CustomArray microarrays are used for genome-wide and focused. Chose from a expanding list of array designs:

  • Gene Expression
  • SNP Genotyping
  • Comparative Genomic Hybridization (CGH)
  • Tiling
  • ChIP-on-chip
  • MicroRNA
  • Resequencing

and more.

Density Choices

Low (2,240)– using 4X2K array chips
Medium (12,000) – using 12K array chips
High (94,000) – using 90K array chips
