The colony counters carried by New Star are designed for the reliable and traceable counting of bacteria growing on nutrient agar in a wide size range of Petri dishes. The most notable thing about our colony counters is that they are one of the lowest priced colony counters in the industry that are also packed with features such as PC-software, interchangeable background plate (white or black), non-glare illumination, and a back button to avoid over counting. Additionally, our colony counters boast adjustable pressure sensitivity and can be used with any marking pen.
