LI-COR's chambers are carefully constructed for ultimate ease of use and minimal environmental disturbance. Internal surfaces are nickel plated to minimize water sorption, and external surfaces are either bright anodized aluminum or covered with titanium dioxide white epoxy to minimize radiation absorptance and maximize emissivity. The chamber gaskets have minimal interaction with CO2 and water vapor, seal tightly, and do not exhibit a permanent memory where leaf midribs and other structures press into the gaskets when the chamber is sealed. In the 6400-05, -07, -08, and -15 leaf chambers, the leaf temperature is estimated from energy balance. In all other chambers, leaf temperature is measured using a leaf temperature thermocouple. |

6400-22L Lighted Conifer ChamberThe 6400-22 Opaque Conifer Chamber is the newest addition to the long line of leaf chambers and accessories available for use with the LI-6400/LI-6400XT Portable Photosynthesis System. The 6400-22L Package combines the 6400-22 Opaque Conifer Chamber and the 6400-18 RGB Light Source, which are also available separately. The 6400-22 is constructed with an opaque plastic material that has excellent resistance to water sorption. It is designed to mate with the 6400-18 RGB Light Source so that users can make response curve measurements on short-needle conifers in the field. The 6400-22L consists of the 6400-22 Opaque Conifer Chamber, and the 6400-18 RGB Light Source. |

6400-02B LED Light SourceThis Red/Blue Light Source not only provides red actinic light source to drive photosynthesis, but also provides a blue component to control stomata. Red LED's are used to provide radiant output at 665 nm (nominal), while blue LED's provide output at 470 nm. The output of the blue LED's is crucial for studying stomatal kinetics (Zeiger, et al., 1987). For more information click here. Download 6400_02B Brochure |

6400-07 Needle ChamberPhotosynthesis rates of long needled conifers are easily measured using the 6400-07 Needle Chamber. The 6400-07 has a 2 x 6 cm aperture and specially designed foam mounting pads that hold up to five needles in the chamber. The 6400-07 allows each needle to be pressed into place in the chamber, where it is held securely in the channels of the foam mounting pad. The chamber top and bottom have replaceable clear Propafilm® windows for excellent light transmittance. A quantum sensor in the chamber provides light measurement at the plane of the needles.

6400-40 Leaf Chamber FluorometerThe 6400-40 Leaf Chamber Fluorometer transforms the LI-6400/6400XT System into the most integrated and powerful Portable Fluorescence and Gas Exchange System available. Stressed Plants? A new LI-COR publication illustrates why the 6400-40 Leaf Chamber Fluorometer is an ideal complement to expand the analysis capabilities of the LI-6400/6400XT System Click here to see why or view the Integrated Fluorescence area of our website. |
Fluorescence Adapter ChambersAdapters to accommodate fiber probe sizes of 2 mm
(6400-10), 8 mm (6400-06), and 10 mm (6400-14) are
available. Each chamber has a quantum sensor that allows
incident irradiance to be measured. |
