CytoSense – C the mobile flow cytometer

Mobile instrument for industrial, shipboard & ferrybox use

At the core of the CytoSense is our scanning & imaging technology, offering:

  • Particle scanning and imaging in one instrument
  • High image resolution
  • Unique particle size range
  • Accurate particle counting
  • Rapid particle analysis
  • a moveable instrument

CytoSense C is suitable for a wide range of applications

Ranging from high frequency HAB and water quality monitoring, algae production support to various biomedical and biotechnology research applications.  Typically onsite locations in order for speedy, flexible and continuous analyses. CytoSense C is mobile and suited for frequent transport, allowing easy change of location and deployment. For instance on ships and attaching to ferryboxes and use in more harsh ‘industrial’ conditions. The CytoSub versions can operate under water and the CytoSense XR is the basic laboratory version.

Unique features of the CytoSense – C

Advantages over typical flow cytometers or dynamic imaging devices:

  • Improved speed & response by performing local analyses with a portable instrument suited for ship & industrial sites.
  • expanded flow cytometry data (scans and images)
  • better detection limits in a single instrument
  • no changing of flow cell or lenses for different particle classes
  • small particle sensitivity: nanoparticles and picoplankton
  • larger and longer particles and filaments: scanning and imaging
  • reliable, unbiased count accuracy and particle size distributions by one-by-one laser scanning in a wide flow cell.
  • effective characterization & classification by:
    • combining laser scatter and fluorescence profiles with photo imaging.
    • ‘free flow’ particle entry without affecting the particles.
  • repeatability and reproducibility by automated analysis.
  • direct analysis (no subsampling), hands free (fixed flow cell & optics for all particle sizes), direct results, fixed
  • long autonomy by clog-free and fouling resistant fluidics
  • low running costs: internal regeneration of sheath fluid

Detailed information and examples on the quality of CytoSense counting, scanning and imaging can be found on the quality page.

The CytoSense is accompanied with user friendly software for data processing & analysis. Detailed information on the data gathered with the CytoSense can be found on the data page.

The CytoSense-C can be accompanied with various accessories, ranging from solutions for online or multi sample operation, as well as automatic fluorescent staining. Explore these on our products page or contact us for information on all available options.

Key specifications

High image resolution

Imaging in flow system/CytoSense generates high resolution images with optical resolution <1µm,   3.3 to 4.6 pixels/µm,  2.3 – 5.3 Mpixel sensors,  528 – 778 um field of view sensors).

Unique particle size range

0.1 um up to 800 um in diameter vs. 2500 µm in length.  Photo’s from 1 µm to max 778 µm.  Laser based scanning detects submicron particles and up, and has a maximum particle length of 2500 µm.

Accurate particle counting

Single cells up to colonies. Wide range of sample flow rates (0.07-16 µl/s) allows low to high particle loads

Rapid particle analysis

CytoSense  is scanning the scatter and fluorescence properties of EVERY particle passing the laser beam (even with the high particle loading, i.e. 10 000 particles per second) allowing quick and detailed analysis of cells.  Result: classic flow cytometry data for small cells <5µm and added morphological properties for particles >5µm.

Clog-free analysis

No need for pre-filtration due to specially designed fluidics with 800 µm diameter minimal orifice throughout

Maintenance free

Recirculating, antifouling sheath fluid design keeping the flowcell free of biofilm buildup

Modular design

The CytoSense C can be configured with up to 2 lasers & 6 optical detectors.


Upgradable with staining module, sampling automation & other accessories.
