Affordable Phenotyping for any laboratory
The LemnaTec LabScanalyzer is a versatile instrument for a broad range of phenotyping applications in laboratories. It allows imaging of many different types of biological samples including plants as well as samples in plates:
- Seedlings and small plants in pots or small trays
- samples in microtiter plates or petri-dishes, e.g. seeds, leaf disks, insects
- samples in beakers, e.g. duckweed for ecotoxicology testing
- detached plant parts, e.g. leaves, fruits, roots, tubers
LabScanalyzers consist of cabinets containing high-resolution RGB cameras together with the corresponding illumination. Depending on the configuration, cameras can be mounted in top- and/or side-view position and lights are available as direct- or back-light panels.
The unique touch-control software facilitates easy handling of experiments and analyses. The software comprises purpose-specific workflows, e.g. seedling growth analysis or duckweed testing, that enable data acquisition and analysis with a few clicks on the user interface. Customised workflows are available on request and can be established interactively.
The workflows of the analytical software provide rapid access to the parameters that are quantitative measures of the phenotypic properties of the samples. Reports are generated as PDF output and as CSV files that enable importing the data in all standard statistical software.
|Sensor||Feature||Description and application cases|
|Visible light camera||Size||Projected object area|
|Count||Number of visually-separated objects|
|Color||Surface color properties, e.g. greenness or characteristic colorations due to senescence, disease, nutrient deficiency, etc.|
|Morphology||Spatial properties of the object, e.g. compactness, convex hull|
|Texture||Spatial arrangement of color or gray values*|
|Movement||Assignment of object movement or activity using time-lapse imaging|
|High sensitivity camera||Luminescence||Emission of luminescence from samples|
LabScanalyzers are available as top-view, side view or as top-and-side view cabinets. A special light-tight cabinet is available for luminescence tests.

High-sensitivity camera for recording luminescence emission
The Growscreen Rhizo LabScanalyzer brings advanced root phenotyping to the lab. The system allows imaging of soil-filled rhizoboxes, that are placed onto a rhizobox holder in the imaging cabinet. Cameras record images from the roots and shoots of the plants.
- Roots in soil – no artificial media required
- Soil-filled rhizoboxes at 45° angle
- Non-destructive – access to roots without digging or washing
- Time-course studies
- Root- and Shoot data for each plant
- High-resolution root imaging
- High-resolution shoot imaging
- Advanced analytical software, machine learning algorithms available

Top- and side-view version
The Lab Scanalyzer is available as top- and side-view version, too. This version is particularly dedicated for imaging potted plants up to approximately 400 mm height and 400 mm diameter. One top-down viewing camera and one horizontally viewing camera enable taking images of the samples from all sides.
