Chambers for Small Leaves

6400-40 Leaf Chamber Fluorometer

6400-40 Leaf Chamber Fluorometer

The 6400-40 Leaf Chamber Fluorometer enables the simultaneous measurement of chlorophyll fluorescence and gas exchange over the same leaf area. The 6400-40 is designed with a uniform, integrated LED light source and PAM fluorometer that easily attaches to the LI-6400XT sensor head, giving the user complete control of the environment surrounding the 2 cm2 leaf area. Measurements of combined gas exchange and fluorescence expand the LI-6400XT's usefulness in assessing a plant's response to stress (read more).

6400-15 Extended Reach 1 cm Chamber

6400-15 Extended Reach 1 cm Chamber

The 6400-15 Extended Reach 1 cm Chamber is designed with a 1.0 cm diameter aperture positioned 8.5 cm away from the main body of the IRGA. Both the top and bottom chambers have Propafilm® windows and leaf temperature is computed using energy balance. The chamber is useful for measuring small leaves that are tightly bunched in rosettes and difficult to clamp in conventional chambers.

6400-02B Red/Blue LED Light Source

6400-02B LED Light Source

The 6400-02B LED source is designed with red and blue LEDs (665 and 470 nm, respectively) to provide uniform intensities up to full sunlight (~2,000 µmol m-2 s-1) over an area of 6 cm2. Mounting simply requires replacement of the upper half of the standard leaf chamber. Powered from the LI-6400XT console, the 02B allows the light intensity to be automatically controlled, which is especially critical for response curve measurements.
