II. Antibiotic Potency Zone Reading
1. What different antibiotic potency assay methods are read and calculated with TRINITY V3?
TRINITY V3 automates USP (United States Pharmacopoeia), EP (European Pharmacopoeia), BP (British Pharmacopoeia), JP (Japanese Pharmacopoeia), AOAC (American Association of Analytical Chemists), US-CFR (Code of Federal Registry) and a custom single plate methods. Giles Scientific may also customize software for your unique method/procedure.
2. What size plates can be read?
TRINITY V3 automatically reads 90-100mm round plates.
3. Are zone diameters viewed on-screen?
Yes. All automated zone measurements are viewed on-screen.
4. Is plate to plate variation accounted and corrected for in USP method calculations?
Yes. Sometimes the depth of agar, temperature differences in an incubator, or other factors may result in conditions that should be corrected for in the calculations of sample concentrations. This is automatically performed by the standard sample layout and calculations in the USP methods.
5. What purpose does the standard curve graph serve? (USP only)
The standard curve graph is displayed on-screen to help the user visualize where the standard and unknown samples are plotted relative to the curve. The graph is not used for calculations; the calculations are performed by mathematical formulas.
6. Is there an option to automatically check for outliers? (USP only)
Yes. Each set of zone measurements can be automatically checked for outliers using the USP Outlier Test. Outlier values are marked on-screen and automatically excluded from calculated results.
7. Can samples be put onto paper disks, into wells cut in the agar, and into metal cylinders?
Yes. Liquid samples may be placed in any of these. Some method guidelines specify which of these may be used.
8. How many standard concentrations can I have?
The number of standard concentrations is defined in each published method.
9. Can a Peni Cylinder Dispenser be used with TRINITY V3?
Yes. A peni cylinder dispenser is recommended to drop 4 or 6 cylinders onto a Petri plate. This provides a more efficient workflow and accurate cylinder placement. Giles Scientific sells peni cylinders and peni cylinder dispensers. Learn more >

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 are 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.
