The fluidlab R-300

The fluidlab R-300 is the smallest, most comfortable laboratory instrument on the market. It combines a full-fledged spectrometer with an automatic cell counter. Its intuitive handling and precise measurements make the fluidlab R-300 the laboratory instrument of the future. With standard cuvettes as well as with glass sample carriers from anvajo a variety of analyses such as absorbance, automatic cell counting and staining-free viability measurements can be performed.

Measure viability without staining: Cytotoxic effects and measurement errors are eliminated by staining-free determination of the viability. Standardized cell count and viability measurements also lead to improved predictability and quality of your experiments.


The fluildab R-300 is the smallest spectrometer in the range from 375 to 700 nm with a spectral resolution of less than 2 nm. The fluildab R-300 is linear in the range of 0 - 2.5 absorbance units with a photometric accuracy of 0.01.


The results are available within 1 minute. A large "field-of-view" (5.3 mm²) and automated measurement of the cell count reduce human error and increase statistical certainty.


The fluidlab R-300 has a wizard for automatic calibration curves. By saving the curves, an automatic calculation and sample quantification is possible.

Erik Klapproth, PhD

Technical University Dresden

"The fluidlab is a great method for cell counting because it is small, you have it in or next to the bench and you can pipette it directly onto the sample carrier acella. The workflow is the same as with the Neubauer counting chamber, but ten times faster and more convenient."

"What we really like about the fluidlab, is that it can be operated intuitively. It is kept simple so that anyone new to the lab can use it. We also like that it gives very reproducible results when measuring a sample multiple times."

"The fluidlab can be used for cell culture and bacterial cultivation at the same time, which is very convenient. The device is easy to handle, we get fast results, the measurement can be performed independent from the location and the instrument does not take up much space beneath the sterile workbench."

Technical Assistant, BASF

"In direct comparison, I actually prefer the fluidlab R-300, simply because it gives me the same reliable results as my reference photometers, but in my laboratory it can be below the bench. In our case, the photometers are located two or three laboratories down the hall. So I don't have to go to another laboratory."

Contact us by phone or e-mail and arrange a personal demonstration appointment. Our product specialists will come directly to your laboratory and you can test the fluidlab R-300 for free. Several times a year we also exhibit at national and international trade fairs. Follow us on LinkedIn, facebook, instagram and twitter to make sure you don't miss a chance to exchange ideas with our team on site.

Our spectrometer is linear in the value range 0 - 2.5 with a photometric accuracy of 0.01 or 1 %. The spectrum can be captured between 375 nm and 700 nm, with a spectral resolution of less than 2 nm. Further information can be found in the performance report of the spectrometer.

Our Cell Counter shows a high correlation (99% accuracy, coefficient of determination R²=0.9956) both with the manual method (Neubauer chamber) and with established automated cell counters.

The determination of viability is performed with the fluidlab R-300 staining-free. Cytotoxic effects are eliminated and pre-analytical steps are reduced. This saves valuable time during preanalytics, increases the stability of cells and avoids contact with harmful staining materials.  The differentiation of dead and living cells works based on our innovative optics identifying the refractive index of cells. The adequate visualisation of the viability application, can be found in our product video.

With a flexible adapter system, the fluidlab R-300 supports both standard cuvettes for spectrophotometric measurements and glass sample carriers of different layer strengths for automatic cell counting and staining-free viability determination.
