Instrument: Turner Designs 700 Laboratory Fluorometer
The TD-700 Laboratory Fluorometer is a benchtop fluorometer designed to detect fluorescence over the UV to red range. The instrument can measure concentrations of a variety of compounds, including chlorophyll-a and fluorescent dyes, and is thus suitable for a range of applications, including chlorophyll, water quality monitoring and fluorescent tracer studies. Data can be output as concentrations or raw fluorescence measurements.
Chl. a was determined during growth of cultures and bottle blooms using a fluorometer (Turner 700) by filtration of samples onto 0.4 μm PC filters and soaking the filters in 90% acetone over night in the freezer (Strickland, 1972).
