The iFOUR - Your Microdispensing Instrument
The iFOUR is a benchtop microdispensing instrument designed for automated ultra-low volume liquid handling from the picoliter to the nanoliter range. Combining non-contact dispensing with industrial-grade mechanics and optics, iFOUR delivers highly reproducible spots and lines across a wide range of substrates – from microscope slides and biochips to microtiter plates and diagnostic membranes.
Whether you are developing diagnostic microarrays, loading biosensors, or preparing MALDI targets, iFOUR helps you miniaturize assays, save precious samples, and standardize your workflows.
Key benefits of the iFOUR
- Unmatched Reproducibility at the Nanoscale:
High spot-to-spot consistency, minimal CVs, ensuring reliable assay results and faster validation. - Optimized R&D Workflows:
Simple, intuitive software, quick setup, integrated QC (head camera/droplet view) to optimize dispensing parameters instantly. - Configurable Versatility for Complex Samples:
Compatibility with diverse substrates (slides, chips, microtiter plates), ability to handle different liquid viscosities (proteins, DNA, polymers), and non-contact operation for delicate reagents.

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.
