Leaf Chambers

image
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.
Opaque Conifer Chamber

6400-22L Lighted Conifer Chamber

The 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.

6400-17 Whole Plant Arabidopsis Chamber

The 6400-17 features a large diameter that allows for measurements of entire Arabidopsis rosettes; this makes it easy to conduct growth studies that were previously difficult to achieve. Interchangeable bottom plates allow the use of 2.5 in. (65 mm) pots or 1.5 in. (38 mm) Cone-tainers™.

6400-18 Red Light

6400-18 RGB Light Source

Designed to be used with the 6400-17, the 6400-18 RGB Light Source provides a powerful tool for whole plant light response studies. The 6400-18 features LEDs with independent control of the intensity and proportions of red, green and blue. You can also define a blended color, or emulate the 6400-02B.

6400-02B LED Light Source

This 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).

6400-05 Conifer Chamber

The conifer chamber is constructed of acrylic for durability and lined with teflon to minimize water sorption. Shoots with needles up to 3.5 cm long can be accommodated in the 7.5 cm diameter chamber. The 6400-05 mounts directly to the sample cell of the system's CO2 and H2O IRGAs.

6400-07 Needle Chamber

Photosynthesis 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.

6400-15 Extended Reach 1 cm Chamber

The 6400-15 Extended Reach 1 cm Chamber was designed for measurement of small leaves such as Arabidopsis, which are difficult to clamp with conventional chambers.

This chamber has clear apertures for natural illumination of the top and bottom of the leaf. The aperture is 1.0 cm in diameter and is positioned 8.5 cm away from the main body of the IRGA.

This design allows you to access and measure small leaves that are tightly bunched together.

Fluorescence Adapter Chambers

Adapters 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.

The clear chamber windows are lined with teflon to minimize water sorption, and can be used with either the standard 2 x 3 chamber bottom, or the 6400-08 Clear Chamber Bottom. The probe is mounted 60° from the leaf plane in all cases.

Dark Adapting Clips

A new accessory for the 6400-40 Leaf Chamber Fluorometer that allows you to dark-adapt leaf samples is now available. Each Dark Adapting Clip consists of two "shutters", and a clip that secures the shutters over the leaf. The Dark Adapting Clip (with the shutters in the closed position) is attached to the leaf; after the leaf is fully dark-adapted, the Clip is secured to the Leaf Chamber Fluorometer, the shutters are opened, and the measurement is taken.
