PHYTO-PAM-II MODULAR Version

In the MODULAR version of PHYTO-PAM-II the multi-color-emitter and photomultiplier-detector units are separated from the control unit; they are instead mounted on an optical unit ED-101US/MP in which a 10 x 10 x 45 mm cuvette is placed.
The modular setup gives flexibility in the choice of detector filters and constitutes an open optical system, providing two additional optical ports for connection of alternative light sources or detectors. Furthermore, it also allows the user to connect a miniature magnetic stirrer to the bottom of the cuvette and to insert a Peltier temperature control “finger” at the top.

The MODULAR version uses the same Optical Unit as the MULTI-COLOR-PAM and also the emitter unit looks similar. However, in terms of electronic components and functionality there are differences. The PHYTO-PAM-II has a photomultiplier detector whereas the MULTI-COLOR-PAM is equipped with a photodiode detector. In addition, the PHYTO-PAM-II applies the 5 measuring light colors simultaneously and uses only one type of actinic light, whereas the MULTI-COLOR-PAM has 5 measuring and actinic light colors that must be applied one by one. See the table below for a list of differences.
IThe PHYTO-PAM-II was designed for the differential analysis of mixed phytoplankton samples, whereas the MULTI-COLOR-PAM is a versatile fluorometer that can be for a variety of kinetic fluorescence measurements (including the analysis of wavelength-dependent properties) on monocultured algae samples as well as leaves.
