The simplest benchtop cell counter

The NORMA XS, based on the new lens-less technology, is the simplest automatic benchtop cell counter for cell culture monitoring. It rapidly measures cell concentration and viability without repeatability compromise. The NORMA XS provides an unmatched accuracy and precision thanks to its wide field of view (29.4 mm2) that allows counting several thousand of cells within a single sample image! No need to adjust focus, brightness or any other parameters, our algorithm will reconstruct cells wherever cells are located… from a few micrometres to some millimetres! There is no sample preparation: no dilution and no Trypan Blue! You just have to take about 3µL of your sample and to deposit it on the measuring slide. These characteristics make the NORMA XS an extremely robust device not fearing temperature variation or any other parameter which can affect traditional focus adjustment.

What are the results ?

Then, the technology directly acquires the light diffraction properties of each individual cells through their hologram images without any settings. Several thousands of holograms are acquired into one single image that is immediately “reconstructed” with our HORUS holographic algorithm to obtain a microscopic like picture; at this stage cells can be segmented. Living and dead cells have significant holographic patterns that can be distinguished and accurately count.

The measurement results are returned by the HORUS software. Each parameter is visible on a simple graphical interface with the possibility to follow several running cultures on user friendly charts.

A strong correlation with the traditional trypan blue methods

Comparatives studies between the NORMA XS and other traditional counters have been performed and have shown their strong correlation and the High Repeatability of the NORMA XS!

The NORMA XS is an innovative automated cell counter and cell viability analyzer designed for precise and accurate cell counting, offering unmatched convenience and reliability.

The NORMA XS boasts several key features:

    • Automatic cell count and viability analysis
    • Small device footprint
    • Sample preparation-free operation
    • Rapid results within a short time frame
    • High repeatability for consistent performance
    • Low sample volume requirement
    • Compatibility with the Trypan Blue method for reference matching

The NORMA XS utilizes state-of-the-art lens-less technology to rapidly measure cell concentration and viability without compromising accuracy. Its wide field of view enables the counting of several thousand cells within a single sample image. With no need for adjustments, such as focus or brightness, users can simply deposit their sample onto the measuring slide, making it exceptionally user-friendly.

The NORMA XS directly acquires the light diffraction properties of individual cells through hologram images, enabling precise cell segmentation. The results, generated by the accompanying HORUS software, provide detailed insights into cell viability, size distribution, aspect ratios, and growth curves, presented in a user-friendly graphical interface.

Using the NORMA XS is effortless:

    1. Extract your unprepared sample using the provided pipette (label-free, undiluted).
    2. Load the sample into the slide chamber.
    3. Insert the slide into the NORMA XS and press measure.

Yes, comparative studies have demonstrated a strong correlation between the NORMA XS and traditional Trypan Blue methods, affirming its reliability and repeatability.

Absolutely, the HORUS software, our premier cell counting and analysis software, is included with every NORMA XS purchase. It is regularly updated by our dedicated development team to ensure optimal performance.
