Upgraded counting accuracy
The high performance telecentric lens allows the Petri dish to be viewed in an absolute vertical position, without perspective distortion. The surface area around the edge of the dish, where the agar meniscus makes counting more difficult, is reduced. By reducing this area from 9% to 5% of the total surface of the Petri dish, counting performance increases. Typical counting accuracy increases from 95% to 97.5%. This is crucial for the pharmaceutical industry, where a colony on the edge of the dish can make the difference between a positive or negative result, especially in the monitoring of air quality in clean rooms. This new feature is standard on the ScanStation 300 model.
