Detailed Description

The QPix™ 420 High Throughput Microbial Colony Picker combines intelligent image analysis with precise automation for fast and efficient screening of large libraries. Capable of picking up to 3000 colonies per hour, it will streamline your workflow. In addition to microbial screening, the system automates several sample preparation and plate handling processes such as transfer of bacterial liquid culture and plating on agar. With a variety of data tracking and assay tools, the QPix Software streamlines the control and management of complex and iterative processes.
