This automatic colony counter PSF-1000 enables to count the number of colonies in a designated area in a fast manner. This device equipped with color camera and enables accurate measurement even culture media with unclear colonies or uneven thickness. The uniform light source solves slight difference between culture medium and colonies. Moreover, accurate counting can be achieved even if there is residue or sedimentation. Standard software is used to manage a variety of specimen like circular, rectangular and spiral types.
