Microbial Colony Picking System
Equipment Introduction
The QPix 420 system offers a range of features to accommodate various requirements for picking of microbial colonies including multiple imaging modes, organism-specific pins, agar height sensor, and specific algorithms to detect variable biological samples. Other functions include sample re-arraying, replication, color screening, and gridding.
