Labtron Manual Colony Counter records colony counts from 0 to 999 and accommodates 50 to 90 mm Petri dishes. Adjustable magnification from 3× to 9× helps users inspect colonies.

White LED lighting improves visibility, while the pressure-sensitive marking pen records colonies during manual counting. A three-digit display presents readings, and an audible beep helps prevent counting errors.

Manufactured for bacterial enumeration and microbial growth assessment in laboratory testing, this colony counting instrument supports agar plate analysis.
