Automatic Model:
High throughput analysis of bacterial colonies or bacteriophage plaques in less than a second. The schuett colonyQuant is comprised of a CCD-Firewire camera (colour) with autozoom and autofocus, a light-proof sample chamber and the software for automated colony counting.

Differentiation by colour, size and shape to be combined at choice by the user. Additional features allow for separating overlapping colonies. Settings to be stored and retrieved via mouse-click for future analysis of similar type samples. The system is straightforward to use and the software is Windows® based. Results are presented as an image on your monitor or in a table exportable to Excel®.

The system has been designed for use with Petri dishes of 60 and 90 mm diameter. As a result of using a LED-array to illuminate the surface of the agar circular from the side a hereto unknown transparency and sharpness for detecting colonies can be observed.

Manual Model:
