The iFOUR - Your Microdispensing Instrument

The iFOUR enables automated ultra low liquid handling and high-precision dispensing of various liquids in the picoliter and nanoliter volume range - your instrument for advanced non-contact microdispensing applications:

  • DNA / protein / cell microarrays
  • Multiplex ELISA
  • Lateral Flow applications
  • Cell transfection arrays
  • Diagnostic biochips, Lab-on-a-Chip
  • Diagnostic biomarker and microbiology assays on multiple substrate (slide, MTP, NC membrane)
  • Drug discovery: small volume GPCR assays, immunoassays
  • Compound library screening
  • Biological screening
  • Spotting to custom-specific substrates and formats
  • Biosensors

The iFOUR is a compact cube of just 50 cm and offers a work surface of 200 x 220 mm.
With a resolution of <0.5 µm and a speed of 500 mm/s, the iFOUR is the perfect solution for demanding applications.
The iFOUR is operated simply and intuitively via the InDot software - a user-friendly interface for experienced users and newcomers. The software is image based, self-explanatory, reflects the deck layout, so you can effortlessly put together your individual process using drag and drop.

Discover our technology

Pulse Shaper

Form follows function

The Pulse Shaper - our newest generation of piezo-wave form generator is already an integral part of your iFOUR. Create your piezo-signal form as a freeform and handle even the most difficult liquids. This feature is unique in its class. Watch the Pulse Shaper video.

Wash Station


The combination of a diaphragm and piston-stroke pump results in an extremely durable washing station for our dispensing needles. No wear and tear promise a long service life as well as minimal maintenance.

Camera System

Reliable feedback

The uncompromising industrial design, camera, lens quality and light flash generation are unique to this device class. Clear and high-resolution images provide quick feedback on your liquid dispensing processes.

LED-Status Display

432 individual LEDs

The iFOUR displays its status via large, bright, definable light patterns. These status LEDs signal each step of the process, and even the remaining runtime.
