The Norma HT is the most simple automatic benchtop cell counter for High throughput parallel culture monitoring. It uses the new and revolutionary lensless imaging technology to rapidly measure viable cell count and viability on up to 48 samples. The Norma HT provides an unmatched accuracy and precision thanks to its wide field of view and label free measurement. Each of the 3 microliter samples is analysed undiluted and several thousands of cells are counted within a single image.

The sample images from the Norma HT are processed by the HORUS software. HORUS returns the number of cell counted, the viability and the cell size. HORUS stores, analyses and displays all the images and results from the current user data or from previous runs.
