The world’s fastest automated cell counter

For years, the choice between manual and automated cell counting has been a difficult one. Manual cell counting on the one hand, is accurate, but time-consuming and very user-dependent. Automated cell counting, on the other hand, is far less accurate but much faster and less user-dependent. On top of that, the disposable counting slides needed for automated counting can be expensive. A tough choice, but now there is a solution.

The Exact can perform a single measurement in less than two seconds*. This is much faster than any other current automated cell-counting system. With traditional systems, the image analysis algorithms have to be processed by a relatively small onboard computer. The Exact can be connected directly to any Windows tablet, laptop or PC, which processes the images much faster.

*  Actual speed can vary depending on the local upload and download speed since the cell count is performed in the Microsoft Azure Cloud.

The all-new Exact is the first automated cell counter that combines the best of both worlds. We combine the best qualities of manual cell counting and automatic cell counting and reduce the costs and counting time. 
​Our Exact is:

  • Fast – Faster than any other automated cell counter currently on the market​
  • Accurate – By analyzing a larger area than other protocols, a higher level of accuracy is obtained
  • Low cost – Not only is the purchase price low, also the Exact works with common reusable glass counting chambers. No consumables are required!

Higher accuracy thanks to the largest field of view of all image based cell counters

The Exact analyses a much larger area than other systems, enabling a higher degree of accuracy. Instead of using only parts of the counting chamber, the Exact analyses the full counting grid. 

Unlike other systems, the CytoSMART Exact is completely open, which allows the user to move the counting chamber. The user can easily count multiple different areas to increase the counting accuracy if necessary. 

Finally there is instant analysis, online reporting and easy reproducible data

The Exact instantly generates a report containing not only the  cell concentration and the cell viability (when using Trypan Blue), but also all images of the counted samples with the counted cells clearly indicated. This is an improvement from traditional automated counting systems. Our highlights:

  • ​Reports are generated in mere seconds by improved computing power
  • High resolution on a high resolution display makes the result transparent
  • USB 3.0 and Cloud technology allow for fast transfer of data to your workstation

​Since all counts are saved in the cloud, you can gain insight into the health and quality of your cell culture from one experiment to the next.

Growth is never by mere chance; it is the result of forces working together.

Much more affordable than manual counting

Most automatic cell counters require disposables. However, if you count manually, you don’t need disposables. We combined these two elements and created an automated cell counter that doesn’t require disposables and counts cells within two seconds. 

The Exact can work with most types of counting slide, including the common reusable glass hemocytometer slides. This means that users can enjoy the benefits of automated cell counting without the costs of disposable slides. Of course, users who wish to use disposables can do so.
