The SphereFlash® is an Automatic Colony Counter that meets all the requirements that may be required in a modern microbiology laboratory. With its Colony Lite software version it performs the colony counting in a simple and reliable way thanks to its world-class software and its patented built-in lightning system. For more demanding users the software can be upgraded to Colonies PRO to increase its capabilities, e.g. setting User’s Permission Levels, LIMS connectivity, Worksheets, Barcode Reading, Reporting, Audit Trail, or CFR21 Part 11. With the optional Halos PRO app, the Sphere Flash unit can be transformed to measure inhibition halos accepting various circle approximation criteria to obtain the corresponding diameters of virtual circle areas. In all versions the lighting is done through LEDs that are oriented to the internal wall of a moving spheric chamber. The result is an unprecedented uniform and reflections-free illumination in a colony counter device. The moving sphere automatically closes the chamber and prevents the area in which the Petri dish is located from any external light. It avoids any reflection or interference of external light, creating a luminous atmosphere without reflections of the walls of the Petri dish or of the colonies. For the transparent media the light by transmission is also available in all versions.
