The iFOUR - Your Microdispensing Instrument
The iFOUR is a high-throughput microdispensing instrument designed for automated ultra-low volume liquid handling and non-contact dispensing in the picoliter and nanoliter range. Engineered for maximum precision and reproducibility, the iFOUR is ideal for advanced life science and diagnostic applications, including:
-
DNA, protein, and cell microarrays
-
Multiplex ELISA assays
-
Lateral flow assay development
-
Cell transfection array production
See a demonstration of a workflow where the Microdispensing Instruments iFOUR sequentially dispenses 3 samples onto 2 target substrates.

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
Service-free
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.

Customisable All-Rounder
The iFOUR offers everything you need for your liquid dispensing processes in the nano and picoliter range. Regardless of whether it's a Control Computer, Electronics, Pneumatics or Wash Pump, with the configurator you are just a few clicks away from your customised solution.
Compact Cubic
With its dimensions of 50[nbsp]cm / 19.7[nbsp]inch, the iFOUR is a microarray printer that offers professionalism with an extremely small footprint: a perfect match for every laboratory workbench.
Bauhaus Design
Your Liquid-Handling System iFOUR is made of high-grade aluminium. It is uniquely sustainable, manufactured from a few selected, basic materials only. No structural elements are painted or contain materials that are not reusable.
Ready to Go
Your droplet dispenser iFOUR comes ready to go, directly out of the box. You need only to attach your favourite input and output devices, like a monitor, keyboard or mouse, and start to change your view on state-of-the-art microdispensing.
