Gusmer Analytical Services
The CyFlow RI-300 is a compact benchtop flow cytometer for microbial analysis and cell concentration reporting. Results between users are consistent and repeatable, and the option to configure the system with an autoloader can greatly increase testing capacity. The CyFlow RI-300 detects all cells in a sample, including viable but non-culturable (VBNC) cells, within minutes, instead of the days or weeks that traditional plating requires. This results in improved lab efficiency and allows for streamlined microbial analysis requirements, saving labor costs and allowing your product to reach the market in less time.
