Norgren Systems CP7200 Colony Picker

The CP-7200 is a simple and efficient pick and place machine designed for high speed colony and plaque picking.

Even when picking extremely dense packed colonies, the CP-7200 will accurately pick only round, isolated colonies. Plating density can be as high as 500 colonies per 4×4 inch agar plate and typical colony diameters can be easily less than 0.5 millimeter. Blue/white selection and plaque picking are also available.

The instrument is controlled with an intuitive graphical user interface, which provides complete real-time control of the intrument.

The system has an on board imaging system for image acquisition. Higly optimized image analysis software automatically locates the position of objects of interest only. The image analysis software also allows individual selection, using a mouse, of any objext in the field of view for custom picking applications.

Twenty tungsten needles, guided by precision linear slides, independently pick and place clones of interest. The input agar or microtiter plate is moved under the pick needle by high precision X,Y stages capable of positioning within 6 microns.

Sterilization is provided by simple water rinse staton and a small, high temperature, bore hole furnace, which quickly heat sterilized needles.

The peak rate is over 7200 picks per hour. The system can pick from round, square or rectangular plate, and it can pick into 96- or 384-well microtiter plates. Using the rearraying software module, clones of interest can be consolidated from 96- or 384-well input plates into either 96- or 384-well plates or square agar plates.
