Petrilyzer
Automated colony counting. Simple workflow. Consistent results.
Petrilyzer combines high-resolution imaging, intelligent analysis and flexible illumination to make microbiological plate analysis fast, consistent and traceable.
Fast
Analyze plates in seconds and increase laboratory throughput.
Objective
High-resolution imaging and automated analysis provide consistent measurements.
Flexible
Configure plate types and analysis parameters to suit different applications.
Traceable
Maintain documented results and plate images throughout the workflow.
From Plate to Result in Seconds
1. Insert the plate
Slide the plate into the Petrilyzer lightbox to begin the analysis.
4. Review the results
Analysis results are displayed in the software, giving you an immediate view of the detected colonies or measurements.
2. View the plate
The plate image automatically appears in the software, ready for inspection.
5. Save the result
Select Continue to save the analysis data and associated plate image as part of the documented workflow.
3. Inspect & analyze
Review the live image, make sure the plate is correctly positioned, then select Continue to start the automated analysis.
6. Ready for the next sample
The system is ready for the next plate, helping you move efficiently through your sample queue.

Intelligent analysis behind a simple workflow
High-resolution imaging
Capture detailed images of each plate using an industrial machine-vision camera.
Flexible illumination
Select the appropriate top, bottom or UV illumination for the plate and application.
Intelligent image analysis
Automatically identify relevant features while filtering unwanted artifacts.
Documented results
Save analysis data together with plate images for traceability and further review.
Designed for a wide range of applications
Petrilyzer supports automated image analysis across a broad range of microbiological plate types, from routine colony counting to challenging low-contrast samples and inhibition zone measurements.

Routine Colony Counting
Reliable counting across common microbiological media.
- PCA
- Spread and surface plates
- Pour plates

Chromogenic Media
Analyze colonies based on color and other visual characteristics.
- E. coli
- Coliforms
- VRBG
- Other chromogenic media

Blood & Enriched Media
Analyze colonies on media where colony appearance and background contrast can vary.
- Blood agar
- Other enriched media

Mould & Low-Contrast Colonies
Enhanced illumination helps improve contrast for challenging samples.
- Mould colonies
- Low-contrast colonies
- Difficult-to-distinguish colony types

Antibiotic Susceptibility
Measure inhibition zones to support antibiotic susceptibility testing.
- Inhibition zones
- Large-zone measurements
- Automated image-based measurement
