Fluorometer

General description:

The QuantaMaster fluorimeter is currently the most sensitive benchtop spectrometer for fluorescence detection (in steady-state mode) available on the market. The QuantaMaster is equipped with a dual excitation and emission monochromator system (for a total of 4 monochromators), enabling the effective elimination of stray light for more accurate measurements. Its exceptional signal-to-noise ratio and high detection limit allow for the measurement of light emission from minute concentrations of fluorescent compounds in solution.
