Allows you to count microorganisms with ease and accuracy.
Supplier: Science First™ 6231050
Microorganisms are far too small to count with the naked eye. However, many of them join together to form visible colonies. To facilitate easy counting of these colonies, it is best to use a dedicated colony counter. Comes with instructions.
- Back-lit counting surface
- 1cm grid distribution; ergonomic angle
- Place sample of microorganisms into Petri dish, and place it on the lighted base
- The counter consists of a grid of 12 x 12 squares, each 1cm on a side
- Arranged in an “X” pattern from corner to corner, the squares are broken down into nine smaller squares, each one third of a centimeter on a side
- Take five or ten squares at random and count the number of colonies in each
- Add these counts together, and divide by the number of squares counted
- This will yield an average colony count per square
