The TopSpot® technology is a noncontact printing method offering an up to now unmatched throughput in the
  production of low- and medium density microarrays. The core of TopSpot® is the micro-machined print head.
  24 or 96 different liquids can  be loaded into the reservoirs of the print head.
  Once loaded, several thousand prints can be made without refill.
  The 24 or 96 different liquids can be delivered on demand and at a pitch of 500 ¥ìm.

Applications

 DNA / RNA microarrays

 Protein / antigen microarrays

 Fabrication of bio-chips

 TopSpot® print module

  The TopSpot® print heads are actuated by the so called print module.
   After filling with samples the print heads are inserted into the module,
  which is then ready for up to 2000 prints.
  To better fit our customer¡¯s needs this module is now also available
  as OEM component for third party integration.
  Whether you plan your own custom made microarrayer, a production
  machine or if just would like to upgrade your old pin-printer, the
  TopSpot® print module almost fits everywhere.
   The TopSpot® print module contains a piezo stack as primary
  actuator, all mechanical parts to support the print head as well as
  precise adjustment stages to control actuation and printing height.
 

 Electronics & Software
   The piezo actuator inside the module is driven by a high voltage
  signal generated by the R5 amplifier. This amplifier is contained with
  in the OEM package and can be controlled by simple software from
  any PC via a RS232 or USB port. Trigger input lines enable easy
  synchronization with external components like x-, ystages or
  cameras.
