Detail Information

This monochromator based instrument uses a high energy pulsed xenon source for excitation. For more than 20 years PerkinElmer has relied on pulsed xenon sources to minimize photo bleaching of samples and provide a long-lived excitation source.

  • Superb performance at an attractive price
  • Versatility, reliability and ease-of-use
  • Pulsed Xenon lamp reduces photo bleaching
  • Large convenient sample compartment
  • Easy-to-use FL WinLab software

FL WinLab™ software, designed for the demanding needs of modern laboratories, operates in the Microsoft® Windows® environment and controls the LS 45. The software combines the user-friendly appeal of a Windows based software package with application specific knowledge PerkinElmer has developed through decades of experience. The result is a powerful system that can be used routinely for quality fluorescence analyses. Specific modes of instrument operation such as Scan, Time Drive, and Ratio Data Collection can be easily accessed in the Application Menu. The excitation and emission monochromators can be scanned independently or synchronously. In addition, the PRESCAN mode is an ideal method development tool for location of peak excitation and emission maxima. FL WinLab includes a validation protocol that automatically checks the instrument performance to ensure that it is operating within specification. FL WinLab, when combined with the LS 45, provides a wealth of tools for data collection and analysis such as:

  • Fluorescence, phosphorescence, bioluminescence and chemiluminescence measurement modes
  • Spectral scanning, including excitation, emission, constant wavelength synchronous and constant energy synchronous
  • 3D Excitation/Emission (EEM) and 3D synchronous scanning
  • 3D kinetic scanning
  • Single- and multiple-wavelength kinetics
  • Simple quantitation by curve fitting with a number of fit algorithms
  • Intracellular ion analysis
