The fluidlab R-300 combines two central lab technologies in one handheld device:
- spectrometry
- cell counting
It can be used to conduct extinction measurements, generate calibration curves, perform cell counts and measure cell viability label-free in under 60 seconds! The fluidlab R-300 can be used with standard cuvettes as well as custom designed anvajo sample carriers. With its size slightly larger than a smartphone the fluidlab R-300 is the most comfortable instrument to use in field tests, inside the lab or directly under the clean bench.
Features:
- Enabling staining-free viability analysis by using next gen holographic imaging
- Measuring directly under the clean bench to prevent sample contamination
- Measuring heterogeneous samples and using the cell size histogram to distinguish between different sized cells
- Cell counting of a broad range of cell types based on neural networks
- Inspecting the full extinction spectrum between 375 nm to 700 nm at one glance
- Generating, saving and retrospectively adapting calibration curves for the quantification of unknown samples
- Transferring quantitative data and images to an external device
- Staying up to date by downloading the newest software version free of charge
- No calibration and regular maintenance needed

Spectrometry & cell counting in the palm of your hand
In this brochure, anvajo GmbH introduces the fluidlab R-300 which combines two central laboratory technologies, spectrometry and cell-counting, in one portable device.
Performance Report: fluidlab R-300 Cell Counter
Reliable and accurate cell counts are crucial for many different purposes such as the maintenance of cell cultures in biological research or in-process controls in industrial bioprocessing. When considering currently available cell counting options, many users ask which cell counting method is better: manual counting or using automated cell counters.
In this application note, anvajo GmbH demonstrate that the fluidlab R-300 can be successfully employed for automated cell counting across a broad range of cell types, including heterogeneous samples and small cells such as PBMCs and yeast cells.
Holographic analysis of single cells
A sensitive and reproducible cell viability assay is essential for monitoring cell health in cell culture laboratories. In this application note, anvajo GmbH compares the performance of the label-free viability tool of the fluidlab R-300 to two well-established colorimetric viability readouts, showing that the staining-free viability tool of the fluidlab R-300 can be reliably used for monitoring cell health and for assessing dose response curves in pharmacology.
fluidlab R-300: Application examples and functions
In this video, anvajo GmbH introduces the fluidlab R-300, the smallest and most practical fluid analysis device on the market. It combines a full UV/VIS spectrometer with a cell counter to enhance analytical performance. A variety of test-specific sample carriers allows the performance of a wide range of fluid analyses such as viability and precise scatter light measurements.
