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.

Main Components of the Basic System
Package GFS-3000

  Control Unit 3100‐C containing the CO2 and H2O analyzer, as well as all components required for the CO2, H2O and flow control

  Standard Measuring Head 3010‐S featuring high application flexibility containing the ventilation system, temperature and light control

  LED Light Source 3040‐L with an LED array providing 90% red and 10% blue light

  AC Power Supply 3020‐N for laboratory use

  Two LiFePO4 Battery Units 3035‐A for field work and Battery Charger LC‐03

 

Modified System Package GFS-3000FL

The modified system package GFS‐3000FL contains the LEDArray/ PAM‐Fluorometer 3055‐FL instead of the LED Light Source 3040‐L. All other components remain the same as in the basic system package GFS‐3000. In terms of price, GFS‐3000FL offers an interesting option to combine gas exchange and fluorescence measurements.

Optional Components and Accessories
of the GFS-3000

  LED‐Array/PAM‐Fluorometer 3055‐FL for illumination of the leaf area and fluorescence measurements

  Fiberoptics PAM‐Fluorometer 3050‐F to analyze fluorescence in sunlight

  Miscellaneous accessories such as cuvettes and adapter plates offering user‐specific application options

  Accessories for product combinations with other Walz systems

Also, the complete equipment will be modified on customer request.
