About Plant Invent
Research instruments shaped by plant science.
Plant Invent develops gas-exchange systems that help researchers observe plant responses with greater throughput, context and comparability.
Our origin
Born from the needs of real experiments.
Plant Invent grew from plant-physiology research at the University of Tartu. The idea was practical: researchers needed a better way to follow gas exchange across several intact plants at the same time.
That research challenge became a family of instruments for small whole plants, larger crops and individual leaves—each built around how scientists actually work in the laboratory and field.
What guides the work
Designed around the experiment.
01 · COMPARABILITY
Measure together
Parallel sampling helps reveal treatment and genotype differences under the same changing conditions.
02 · CONTEXT
Keep plants intact
Non-destructive measurement supports repeated observations across the course of an experiment.
03 · PRACTICALITY
Fit the workflow
Instrument and cuvette choices are matched to the plant material, setting and question being studied.
65+
peer-reviewed studies using Plant Invent technology.
Scientific use
Evidence is part of the product story.
Plant Invent systems have supported published work across plant physiology, environmental response and phenotyping. A focused research section makes it easier to see how the technology has been used.
3systems for different samples and settings
8parallel cuvettes supported by Jyrkki
