BZG 40

WTW colony counter BZG 40

Colony counter to count microbial colonies in petri dishes - easy, quick and reliable counting with great ease of use

  • Counting accuracy by adjustable sensitivity
  • Optimal lighting by adaptable intensity or direction
  • Documentation via interface or memory

The colony counter BZG 40 is easy to operate; it allows for a fatigue-free and safe work environment by the problem-free counting mechanism: the resting surface for the petri dish is sensitive to pressure; if the colony is tapped on the dish with the counting pen, the counter is activated. For optimized operational adaptation, the counting sensitivity can be adjusted individually. All generated data can be saved and transferred to a computer, if you wish.
