Interscience Counting Grid for 90mm Petri Dishes (Each)

The Interscience circular counting grid is designed to improve accuracy and consistency when counting colonies on 90mm petri dishes. The clear grid layout helps laboratories visualise colonies more easily, making manual counting faster and reducing the risk of errors during routine microbiological analysis.

This counting grid is commonly used alongside Interscience colony counters, providing a reliable setup for plate counting in food microbiology, environmental monitoring, water testing and quality control laboratories.

For complete workflows, laboratories often use this grid with petri dishes, prepared culture media ensuring accurate results from incubation through to final colony counting.

Supplied individually, this counting grid is an essential accessory for laboratories carrying out regular microbial enumeration and plate counting.
