After inserting a plate into the TRINITY V3 drawer, a color digital image on-screen is analyzed instantly with zone diameters displayed. The user reviews and confirms, or can adjust any zone size. Few (if any) zone measurements need adjustment; most plates require only a quick visual check. Threshold/sensitivity settings allow for precise, consistent reading of difficult plates. After all plates are read, calculations are displayed. All plate images may be saved and archived for future review.

TRINITY V3 eliminates all transcription and calculation errors, providing significant labor savings and standardization of testing. Regular software updates including new features are available via CD or website download. TRINITY V3 requires no routine maintenance; it contains no motors or moving parts, only solid state digital electronics.

An electronic caliper is also included with the TRINITY V3. This provides backup reading for the automated system and reading of large single plate assays. Learn more

TRINITY V3 includes Installation Qualification, Operational Qualification, Performance Qualification validation and complies with 21 CFR Part 11 for electronic records. Learn more

Plate Layout
The layout of the samples on the plates and number of plates per set is outlined exactly in the published methods of the USP/CFR/AOAC. Testing can be incorporated into the laboratory routine without altering current manual methods, materials, organisms, plate sample layout pattern, or government

documentation. Some flexibility in the layout is allowed.

Test Results
Test results can be printed, saved, and exported. The standard curve is plotted with the average of standard (known) concentrations. The plotted curve is shown to help visualize on-scale and off-scale test result values. A correlation coefficient, slope and intercept are also displayed.

All calculated values are displayed on-screen. Unknown concentrations are calculated mathematically, based on the standard regression formula derived from the standard curve.

"Easy setup and validation of TRINITY V3 Zone Reader"

"It has been pleasure working with the Giles Scientific sales and service team as we implemented the TRINITY V3 zone reading system for our USP antibiotic potency assays.  Their qualification documentation was very simple and straightforward, and the support we received has been great. The system was completely implemented in just a few weeks and we’ve had nothing but praise from the analysts in the lab.  The TRINITY V3 system has been very reliable and much easier to use than our old system.  We’re looking forward to many years of working with Giles Scientific."

"TRINITY V3: A Reliable Instrument for our USP Antibiotic Potency Assays"

"The TRINITY V3 is flexible and very reliable for our USP antibiotic potency assays. The optics produce high quality images and the software interface is easy to use and navigate. It allows for visual verification of the inhibition zones on screen. TRINITY V3 is also fully compliant with 21 CFR Part 11 requirements."

"Great Customer Service and Support from Giles Scientific!"

"TRINITY V3 is a well-built and easy to use device that never let us down in three years. It also enables us to produce faster results on our USP antibiotic bioassay in animal feeds. Since we have had TRINITY V3 we have asked for minor adjustments specific to our needs. These demands were treated rapidly and efficiently and the customer service is great!"

"TRINITY V3: User friendly system with consistent results"

"TRINITY V3 instantly reads and calculates the zones of inhibition for our USP and MYCO antibiotic potency tests. It has significantly reduced our labor time for this assay. The software is very user friendly system and provides consistent results for our microbiology lab. I have worked with Giles Scientific for several years and their service and support is excellent."
