Colony Counter

PSF-7100 is the top-level model boasts a resolution of 35 microns. It can also be used for counting stained cells. 

PSF-7100W also supports 240×240mm dishes.

 

Features

• Uniform light source solves slight difference between culture medium and colonies. Necessity of uniform light source over the whole petri dish.
• Measurement functions when there is a residue or a sediment.
• Automatic delete function for a widespread colony.
• Manual adjustment for measurement result.

* Optional software is required to inhibition zone measurement. This software is standard only in PSF-7100W.
** For square petri dishes, use one that is smaller than the maximum count area.
*** It is possible to change the height position of the top lighting. By this function, the outline of colonies can be clearly photographed.
