JUNIOR-PAM Teaching Chlorophyll Fluorometer Miniaturized PAM Fluorometer for Undergraduate and Graduate Training

JUNIOR- PAM Teaching Chlorophyll Fluorometer Pulse-amplitude modulated (PAM) chlorophyll fluorometry in combination with saturating pulse analysis of fluorescence quenching is now a standard technique to assess plant photosynthesis. In the 1990s, the Walz Teaching-PAM fluoro meter (PAM-200) carried PAM fluorometry into university classrooms. Since then, there has been considerable progress in LED and PC technology, enabling the development of a powerful and versatile, and at the same time compact teaching fluorometer: the JUNIOR-PAM. FEATURES The JUNIOR-PAM excels by its simplicity and ease...

Chlorophyll Fluorescence Analysis PAM-Fluorescence The JUNIOR-PAM detects only the fluo escence excited by its evenly pulsed r measuring light: the instrument is insen sitive to continuous light. Hence, signal changes reflect changes in the yield of chlorophyll fluorescence, which is complementary to the yields of photochemistry and heat dissipation in photosystem II (PS II). Saturating Pulse Quenching Analysis The JUNIOR-PAM’s low measuring light intensities and its ability to deliver strong light pulses permit determinations of F0 and FM , the minimal and maximal fluorescence yields of a...
