Microarray printers and instruments

For the last 20 years, Arrayjet has been involved in the design and manufacture of microarray instruments. Arrayjet printers are capable of depositing samples with the help of inkjet technology. This is up to 100 times quicker compared to so-called “conventional” dispensing or pin-spotting systems.

They also have a bigger output capacity, printing up to 1000 slides (or 200 microplates) in a single batch. The new Mercury instrument range from Arrayjet is the outcome of five years of R&D and comprises the most sophisticated advancements in inkjet bio-printing.

Advantages of inkjet


  • The inkjet print head has the potential to deposit 700 drops per second, thereby printing on-the-fly
  • A complete 384-well plate could be printed, in triplicate, onto 100 microarray slides in just 25 minutes

Contactless printing

  • The printable surface has been safeguarded from damage as a result of contact pins
  • The piezoelectric print head does not denature samples or get clogged


  • Perfect for printing onto plates, membranes, PCR chips, slides and microfluidic devices
  • Printers are modular and satisfy requirements from R&D to bulk manufacturing


  • Precision feature size: 50 μm to 1 mm
  • User-defined spacing: Increments of 1 µm
  • Low intra- and inter-slide CVs of <5%
  • Accurate spot volume: 40 pL to 10 nL


  • Real-time print evaluation and parameter monitoring are available
  • Intuitive software, twin quality control cameras and automated spot reprint in real-time
  • HEPA filtration and environmental control operating temperatures range from 4 to 25 ºC

Arrayjet microarray printers have been combined with the JetSpyder™ — Arrayjet's patented liquid handling device. This device allows the aspiration of biological samples into an industrial-grade inkjet print head and uses as little as 0.5 µl sample for 1000 slides to be printed.

Without any contact, the print head crosses the print surface and then deposits the sample at a rate of 700 drops per second.
