The iFOUR
The iFOUR microdispensing instrument provides precise, non-contact liquid handling from picoliters to microliters in a compact benchtop format. It integrates seamlessly into existing lab setups and complements conventional pipetting and liquid handling workflows.
Dispensing Technology
Our non-contact microdispensing technology covers volumes from microliters down to picoliters and is designed for flexible, high-precision liquid handling. It is ideal for limited and sensitive samples in applications such as microarray printing and assay miniaturization.
Applications
The iFOUR is a reliable tool for advanced microdispensing applications in diagnostics and life science: from developing tests and loading biosensors with proteins, aptamers or oligonucleotides to creating microarrays on chips, slides and microtiter plates.
Precision in every drop: Tailored solutions for your application
Whether you are developing diagnostic microarrays, biosensors, lab-on-a-chip devices or cell-based assays, the iFOUR supports a broad range of substrates and sample types, ensuring a seamless transition from R&D to production.
High-Density Microarray Printing
Achieve high-density microarray printing with excellent spot-to-spot consistency on slides, membranes or custom substrates. Non-contact picoliter dispensing keeps proteins, DNA and antibodies highly active with low CVs.
Advanced Biosensor Functionalization
Precisely functionalize biosensors by coating electrodes and optical sensing areas with aptamers, antibodies or enzymes. Camera-guided alignment ensures accurate placement even on very small sensing spots.
Lab-on-a-Chip & Microfluidic Loading
Load lab-on-a-chip and microfluidic devices with pL-µL accuracy into micro-channels, reaction wells and complex chip geometries. The compact benchtop iFOUR supports fast prototyping and small-scale production.
Seamless Assay Miniaturization
Move from conventional pipetting to high-precision pico- to microliter dispensing for multiplex diagnostics and drug screening assays. The iFOUR reduces sample consumption and accelerates validation of miniaturized workflows.
