Astor 20 Colony Counter
The innovative counter based on pressure impulses
The new Astor 20 Colony Counter is very easy to use. Thanks to its Petri dish holder, back-lit and sensitive to pressure, the enumeration of the microbial grown colonies on the agar surface can be performed by a simple and common marker. The Petri dish holder is back-lit by LED's: this new technology grants a better light diffusion, a greater reliability and a minimum power consumption (2 W, as a total).
Astor 20 does not require any particular marker, connected by a cable.
