Colony Picker

Manually picking colonies from an agar plate or re-arraying a genomic library in microplates one toothpick at a time

is a very slow and tedious task and can lead to repetitive motion injuries. We have invented a simple hand tool that

reduces the repetitive motion by a factor of twelve and greatly accelerates the picking and placement process. It also

eliminates the difficulty of handling toothpicks aseptically.

The Colony Picker is amazingly easy to handle while making precise "picks." The Colony Picker is operated with

just one hand and the picking position remains the same for all pins thus providing a consistent hand/eye coordinated

target. Once all 12 pins have been used to pick colonies or re-array a library they are inoculated in a 96 well microplate.

The pins are sterilized by dipping in ETOH and flaming. The Colony Picker is designed for right handed operation.


We also provide a rack that holds 4 Colony Pickers in every other row of a 96 well microplate. After four rows have

been inoculated the microplate is shifted 9 mm and the remaining 4 rows are inoculated.   The rack system provides

a fail safe system against double inoculation of the same row of wells.  The Colony Picker and the rack are compatible

with conventional and deep well microplates
