Target holder options for Marathon series of microarray spotters

Arrayjet offer standard and custom holders to accommodate a variety of substrates;

  • Slides: Easy-load trays with individual springs to hold each slide accurately in place with reload accuracy of +/- 10 µm. 
  • Microplates: Trays for microarray-specific two-part plates or pre-moulded polymer plates. 
  • Vacuum deck: Available with a standard slide or plate mask, or a custom mask.  The vacuum tray is available with integrated heating and/or cooling.
  • Heated/cooled decks:  All target holder options are available with integrated heating and/or cooling.  The temperature set point of the printing surface can be programmed to reach a specific temperature (-10 to +40 °C), or to respond automatically to environmental conditions in order to achieve dew-point.
  • Custom: Arrayjet can work with your design team to create a compatible holder for any target.  Custom print programming is also available for any target.
