BZG 30
One and two and three...
The most time-consuming part of carrying out a microbial count is the actual counting process on Petri dishes. Colony counters facilitate this task and as a result are an essential help in every bacteriological laboratory. Their particular advantages are the easy, rapid and reliable counting of bacterial colonies with very sample handling. The colony counter BZG 30 is easy to use, and allows fatigue-free and safe work thanks to its problem-free counting mech-anism: The surface on which the Petri dish is placed is pressure-sensitive; marking the colonies on the Petri dish with the marker pen activates the counter. The pressure sensitivity is adjustable for optimal adaptation to the operator.
Intelligent counting technology
The colony counter BZG 30 has an acoustic check signal and automatically compensates for the weights of different Petri dishes; the pressure sensor system also provides uniform sensitivity over the whole of the working field. Zero-voltage protection guards against short inter-ruptions to the mains supply.
The ring-shaped lamp provides uniform working field illumination; the magnifier offers distortion-free optics and can be individually positioned on its extremely flexible arm. Versatile work is guaranteed by select-able direct or indirect illumination. Direct illumination is particularly suit-able for nutrient agars with a dark back-ground; indirect illumination for lighter agars. Colony counter BZG 30 has an additional counter input for counter marker KS 30 and is supplied with an interchangeable Wolffhügel grid.
