GFS-3000
The portable GFS-3000 is a high precision system for the assessment of plant
photosynthesis (CO2-uptake) or respiration (CO2-release) and transpiration – also in
combination with optical measurements.
Gas exchange measurements rely on the basic principle that changes in CO2 and H2O concentrations are determined when air passes through a climate controlled chamber containing a plant sample.
The GFS-3000 is suitable for controlled laboratory settings as well as demanding field conditions.
The GFS-3000 perfectly complements with other Walz systems giving access to numerous aspects of photosynthesis research.
The Portable Gas-Exchange and Fluorescence System GFS-3000 enables wide range climate control. All environmental parameters relevant for plant photosynthesis (CO2, H2O, temperature, light, ventilation and flow) can be controlled automatically and over the full physiological range.
Optional fluorescence modules further expand the system’s capability. Experimental protocols for automatic light-curves or automatic CO2-curves can be easily programmed.

GFS-3000 & DUAL-PAM-100
System Combination
The most sophisticated combination of Walz instruments is the GFS-3000, together with the P700 & Chlorophyll Fluorescence Measuring System DUAL-PAM-100, using the specially designed DUAL-PAM Gas-Exchange Cuvette 3010-DUAL.
This novel setup is the first commercially available system allowing simultaneous analysis of PS I and PS II photochemistry simultaneously with CO2 gas exchange.

GFS-3000 with DUAL-PAM Gas-Exchange Cuvette 3010-DUAL and DUAL-PAM-100
The cuvette 3010-DUAL enables control of temperature and gas composition. Hence, the wide range of information provided by the DUAL-PAM-100 can be obtained under climate controlled conditions concurrent with gas exchange data.
The small area of the cuvette 3010-DUAL (1.3 cm2), makes it very suitable for experiments on single Arabidopsisleaves. Also the P515/535 Emitter and Detector, which enable the DUAL-PAM-100 to measure the electro-chromic carotenoid shift and “light scattering”, is compatible with the cuvette 3010-DUAL.
