  • Perkin Elmer LS 55 Fluorescence Spectrometer
  • This is a 0.1nm resolution, compact spectrophotometer that uses the windows-compatible FL WinLab™ software that can measure fluorescence, phosphorescence and bio- and chemi-luminescence using a pulsed Xenon lamp source.

Purpose of use

Instrumentation The LS55 Perkin Elmer Fluorescence Spectrometer, 230V uses a pusled Xenon source to measure fluorescence, phosphorescence, chemi- and bio- luminescence. The FL WinLab™ software has different modes operation like Scan, TimeDrive, and Ratio Data Collection, increasing the versatility of the instrument. The excitation and emission monochromators can be used independently or simultaneously. The instrument also has the ability to prescan the sample to determine the excitation peak and maximum emission.

Included with the LS55 Perkin Elmer Fluorescence Spectrometer, 230V is a single-cell sample holder that can hold up to a 1cm pathlength cell and has the option of stirring. The automated polarizer has two filter wheels that have both a horizontal and vertical polarizing element. The polarizer is controlled by the software.
