The QPix® Microbial Colony Picker leverages best-in-class colony picking technology to alleviate bottlenecks and quickly, accurately, and efficiently screen through massive genetic libraries. The easy-to-use, intuitive software guides users through setting up colony picking runs where precision robotics pick the right colonies every time.. 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.
Data is automatically recorded into the machine’s database, providing users with a complete audit trail and sample tracking, ensuring that no data is ever lost. Our modular, scalable series of colony pickers allows groups of all sizes to increase the accuracy and throughput of their workflow, while still allowing for future throughput growth.
The QPix colony pickers support a wide variety of microorganisms and multiple selection modalities, including fluorescence intensity, blue/white selection, size and proximity, and zone of inhibition.
A suite of organism-specific pin and agar sensor ensure efficient picking. The system delivers a picking efficiency of >98%, allowing you to walkaway with confidence.
A host of sterility features are available including a UV light for sanitizing the interior of the instrument, as well as pin washing, and halogen drying of pins.
