III. Colony Counting
1. What types of colony count plates can be read automatically?
A variety of plate types and sizes can be read including: Plates up to 150mm in diameter, 3M™ Petrifilm™, Ames assays, phage/plaque assays, pour plates, spiral inoculated plates, filter membrane agar plates (with or without printed grids), and chromogenic agars.
2. Can the colonies be counted when there is food or debris in the agar?
Yes. Most food and debris is distinguished from colonies by color and/or size.
3. Can blood and dark colored agar be read?
Yes. Clear, opaque, blood and dark colored agar can be read. TRINITY V3 contains a closed cabinet with upper and lower LED lighting for both light and darkfield, or combined. A closed cabinet (drawer) is critical for difficult reading situations.
4. Can touching and overlapping colonies be divided into separate counts?
Yes. Colonies that are touching or overlapping can be separated by size and shape into multiple counts automatically. Large colonies may be divided into multiple counts based on a flexible size variable. These settings can be turned on or off. These colonies can also be manually added or deleted from the automated count using the touch-screen or mouse click.
5. What is the smallest detectable colony read?
The smallest detectable colony is 0.05mm and smallest colony size discrimination is 0.08mm.
6. Can plates that are divided into several segments be read automatically?
Yes. Entire plate, half-plates, quadrants, or custom defined areas can be read. Each plate segment is counted independently in addition to total plate count.
7. Are colonies differentiated based on size?
Yes. Colonies may be differentiated based on size. Up to 10 size ranges can be defined and counted simultaneously. Counted colonies may be differentiated based on color similarities with user adjustable color ranges. One or any number of user-defined colors can be counted as well.
8. Can I add colony counting software after I purchase TRINITY V3?
Yes. Customers may purchase colony counting software at any time. Software is provided via website download.
