VWR® Counter-Pen™ Colony Counter

Supplier: VWR International
VWR® Counter-Pen™
Made of durable ABS plastic, this combination marker and digital counter is designed for the lab and plant.

  • LCD display
  • Counts up to 99,999
  • Simultaneous touch, sound, and count

Use the unit to count cell growth on Petri dishes, inventory parts, and tally samples received. Each time a black mark is made with the felt-tipped pen, the unit automatically sounds a beep, and the LCD displays the count. Touch, sound, and count occur simultaneously. Even when interrupted, marks hold your place and the counter holds your total, making the unit virtually error-proof. Unit features audio/visual counts to 99,999 with reset button, on/off switch, and pen cap.
