Amiscience's FluoroQuik cyanobacteria fluorometer kit is a low cost hand held instrument for use in the field or the laboratory. Its simple touch screen design allows for fast and direct measurements of Phycocyanin, Chlorophyll, and the ratio between the two in a single read out, all with a single sample and one touch of the screen. Units can be read out in RFUs or in standard concentration units of ug/L. Useful for tracking dynamic changes in phytoplankton communities within a waterbody and assisting in the forecasting of potential harmful algal or cyanobacterial blooms, it is currently being used by the Cyanobacteria Monitoring Collaborative (http://cyanos.org) as a low cost tool for lake associations, drinking water utilities, local, and state and federal entities to monitor real time water quality conditions. The FluoroQuik operates on either DC AA batteries for in the field use or AC power for benchtop use. The fluorometer comes equipped with a protective carrying case, starter cuvettes and pipettes, and software for internal data storage and retrieval.
