overview
Introducing
the fluidlab R-300
The fluidlab R-300 was the first compact device to combine automated digital cell counting and embedded spectrometry in a single instrument. Developed to demonstrate the capabilities of anvajo’s miniaturized optical systems, it continues to serve as a trusted reference for partners developing next-generation analytical solutions.
With hundreds of field installations, published performance reports and verified real-world workflows, the R-300 represents the reliability and precision of anvajo’s core technologies.
Core capabilities
Key technologies demonstrated by the R-300
The fluidlab R-300 showcases the versatility and performance of anvajo’s optical platform:
- Digital cell counting with high statistical accuracy
- Label-free viability detection via holographic microscopy
- Integrated spectrometry (375–700 nm) for absorption and scattering
- Time-series and extinction measurements
- Compact, maintenance-free hardware design
- Minimal sample volume (10–20 µL), ideal for valuable or limited samples
OEM relevance
From device
to OEM module
As a reference platform, the fluidlab R-300 demonstrates how anvajo’s core optical technologies can be transferred into OEM components and integrated systems.
It combines label-free cell analysis and embedded spectrometry in a compact, maintenance-free design, illustrating how miniaturized optics, software-driven analysis and real-time data processing can work together in a production-ready setup.
For OEM partners, the R-300 serves as a validated blueprint for building compact analytical devices, optical modules or automated workflows based on proven field performance.

Device
The fluidlab R-300 uses the label-free technique of digital holographic microscopy (DHM) to analyze cell number and viability directly in the cell culture environment. Contrary to brightfield microscopy, DHM does not use optical lenses but generates so-called ‘holograms’ of the cells, which are analyzed by a computer.
