FluoroMax-4 Spectrofluorometer

Steady-state fluorescence spectroscopy investigates the long-term average fluorescence of a sample when irradiated with UV, visible, or near-IR light. The FluoroMax-4 is a compact spectrofluorometer with high sensitivity. The sample chamber allows a wide variety of accessories for special samples and allows experimentation with different sample schemes. FluoroMax-4 is controlled by PC driven FluorEssence™ software. On start-up, the system automatically calibrates and presents itself for new experiments, or stored routines called from memory. Publication-ready plots and data-analysis are based on Origin®.

Specifications include:

  • Excitation: 200950 nm, optimized in the UV
  • Emission: 200950 nm, optimized in the visible
  • Bandpass: 030 nm, continuously adjustable from computer
  • Wavelength Accuracy: ± 0.5 nm
  • Scan Speed: 80 nm/s
  • Integration Time: 1 ms to 160 s
  • Emission Detector: Photomultiplier, range 200850 nm
  • Reference Detector: Photodiode selected for stability
  • Signal-to-Noise Ratio: 3000:1 (steady-state mode)
