Lightweight and durable, this pen is ideal for microbiology laboratories, research facilities, and diagnostic centers that require reliable colony identification and tracking.

Use the Counter-Pen to count cell growth on petri dishes, to help in inventory processes, or to tally samples received. The Counter-Pen is a permanent marker and a digital counter all-in-one device. The device sounds an audible beep every time a mark is made. With touch, sound, and counting occurring automatically and simultaneously, counting procedures become error-free and hassle-free - even when interrupted. Always pick up your pen and your count right where you left off.
