Overview

The PerkinElmer LS 55 Fluorescence spectrometer offers flexibility, versatility, reliability and ease-of-use. Based on our popular LS-50B, the LS 55 spectrometer includes a host of auto-mated accessories and software to address a wide range of bio research applications. The LS 55 is built on PerkinElmer's heritage of sensitivity and reliability. A wide range of automated accessories have also been developed for the system making it the system ideal for bioresearchers conducting:

  • Microplate-based measurements
  • Polarization
  • Anisotropy assays
  • Intact cell work
  • Analysis of protein suspensions
Whether your application requires fluorescence, phosphorescence, chemi - or bio-luminescence, the LS 55 is ready for the challenge. Optical performance you can count on our monochromator based LS 55 uses a high energy pulsed Xenon source for excitation. For more than 20 years PerkinElmer has used pulsed Xenon sources to minimize photo bleaching of samples and provide a long-lived excitation source. The variable slit and holographic gratings provide flexibility with very low stray radiation. We've incorporated holographic gratings on both the excitation and emission monochromators to further reduce stray light and improve the system's already impressive performance. And a newly designed reference signal system has been added to provide users with much more control over signal dynamics. This is particularly useful for samples with widely differing intra-sample signal size. For example, the LS 55 signal system has reduced noise by a factor of about 5 for intracellular ion analyses, and increased data transfer rates by a factor of 10.
