At Synbiosis, we have pioneered the development of automated colony counting since 1985. Today we offer three world leading colony counters - the ProtoCOL 3, Protos 3 and the aCOLyte 3. Within these ranges you’ll find the perfect colony counting system to fit your budget and the level of sophistication your environmental monitoring and water sampling needs.

Colony counts in seconds

You can use a ProtoCOL 3, Protos 3 or an aCOLyte 3 for microbial limits testing in air quality and water monitoring applications to quickly provide you with a precise total count. These systems can accurately count bacteria (Staphylococcus and Bacillus) and yeast from active air samples on settle and contact plates. The systems are so flexible they can even count colonies on spiral and multi-sector plates, as well as filter paper on plates post membrane filtration.

Excellent colour detection

With the ProtoCOL 3 and Protos 3 you’ll find unique colour differentiation technology. So if you’re screening raw, potable or recreational waters to determine the presence of total coliforms or to count different types of bacteria such as Legionella on selective agar, ProtoCOL 3 and Protos 3 can do this quickly and easily.

Rapid analysis

With the simple to use software in Synbiosis colony counters, you can automatically distinguish true colonies from debris or bubbles in the media. The software saves you time by effortlessly delivering you true to life images and count data in seconds, which you can store and return to when you need it.
