Featuring many new technological developments, the iFL is designed to provide plant physiologists with the most advanced, accurate and reliable experimental capabilities. The iFL features a highly accurate, miniaturised infra red gas analyser (IRGA), housed directly inside the leaf chamber head, with a fully integrated pulse modulated chlorophyll fluorometer. Thus providing researchers with measurements of an expanded range of photosynthetic parameters. Additional photosynthetic parameters These photosynthetic parameters include Γ* and Rd, which can be used in subsequent automated experiments to measure gm, J, and Cc. So providing researchers with more detailed diagnostic information on the photosynthesis process and its adaption to different environmental conditions and stresses. These long-term experiments, such as Laisk protocols, are conducted without any interr

Full automation - without interruption The unique differential in time design of the ADC IRGA, with automatic zeroing, ensures that there is no calibration drift. This means that long experiments such as entire Laisk protocols may be performed, fully automatically, without any interruption for cell “matching” or any other intervention. Simply set up an experiment, walk away and return when the experiment has finished. Several hours of automated experimentation can be initiated with one touch of the iFL screen. For example a complete Laisk may be performed together with post processing, directly...

The iFL can be used in three modes • Automated combined system • Advanced gas exchange system • Powerful chlorophyll fluorometer Automated combined fluorescence and gas exchange system The iFL provides preprogrammed, fully automated routines of the Laisk, Kok and Yin protocols for the determination of Γ* and Rd including all post processing. These determinations may then be automatically transferred to subsequent experimentation for measuring gm, J and Cc including A/Cc curves. Whilst the Laisk protocol is the most frequently used protocol for determining Γ* and Rd, Kok is sometimes preferred...

Truly portable for field research Weighing only 5.2kg (including battery) the iFL is a truly portable and versatile instrument for field plant physiology research. The highly power efficient iFL operates continuously from a single battery charge for up to 8 hours.
