The bbe AlgaeLabAnalyser (ALA) offers the simultaneous determination of Simple operation



chlorophyll concentrations, transmission, and – as an option – the photosynthetic Direct measurement without

activity of microalgae. Chlorophyll is excited by coloured LEDs and the fluorescence sample preparation by

emission is allocated to the different algal classes.

Laptop supplied

The AlgaeLabAnalyser enables direct measurement without sample preparation by filtration or solvent. The fluorescence signals f0, f, fm are used to calculate the Integrated stirrer

photosynthetic activity applying the Genty parameter method. A yellow substances PC operation with bbe ++

(FDOM) compensation is also used to exactly calculate the total chlorophyll content.
