FLUORESCENCE SPEC PACK / FLUORESCENCE SPEC PACK CUV BASIC
With great sensitivity in the Visible range, the SPEC PACK CUV BASIC is the most affordable solution for fluorescence available.
Using a SPEC STD FL spectrometer with 200 µm slit and collecting lens for greater sensitivity, the LS-LED Light Source with high power LEDs and where due to the LED slide principle can easily change the excitation wavelength, large core optical fibers and the flexible cuvette holder CH.
GREAT PERFORMANCE AT A SHOCKING PRICE!
Eosin Y was tested as a common dye used in molecular biology applications with quantum yield of 0.67. The results obtained were in the picomolar range. Four solutions were prepared in ethanol with concentrations of 19.3, 77.2, 115.8 and 154.3 picomolar. The emission wavelength considered was 544 nm.
The instrumentation used was a Fluorescence SPEC PACK CUV BASIC configured with a 495 nm high power LED. The results are below:
The pre-configured solution Fluorescence SPEC PACK CUV BASIC includes the following components:
Pre-configured solution for Basic Fluorescence using cuvettes including:
SP-STD-FL; LS-LED (inlcuding one LED in visible range); CH and OF-UV-1000-50 (2x)
