|Description|| The gold standard for automated bioresearch:|
Developed for a wide range of bioanalytical applications • Based on decades of experience in Luminescence Spectroscopy • Automated accessories designed for bioresearch • Holographic gratings for reduced stray light • Versatility, reliability and ease-of-use • Pulsed Xenon lamp reduces photo bleaching • Large convenient sample compartment • Easy-to-use FL WinLab software • Includes automated polarizers
The PerkinElmer LS 55 Luminescence 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 PerkinElmers 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
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 systems 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.
Powerful software controls your entire analyses:
Our FL WinLab software is designed for demanding laboratories. It seamlessly combines PerkinElmer's extensive application specific knowledge and instrumentation control with the ease-of-use provided by the Windows operating environment. Specific modes of instrument operation such as Scan, Time Drive, and Ratio Data Collection can be easily accessed from the Applications Menu. Excitation and emission monochromators can be independently or synchronously scanned, while the Prescan mode is ideal for method development and locating 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. With its unique set of accessories and software applications, the LS 55 offers the most powerful and flexible system for data collection and analysis.
Measurement Modes for the LS 55:
Fluorescence, phosphorescence and bio- and chemi-luminescence measurement modes. • Excitation, emission, constant wavelength synchronous, and constant energy synchronous spectral scanning. • 3D excitation/emission scans, 3D synchronous and kinetic scans. • Microplate measurements with fixed wavelength, wavelength program or automated spectral data collection. • TLC plate, electrophoresis gel or other flat sample types can be analyzed with our Plate Reader accessory. • Single and multiple wavelength kinetics • Simultaneous kinetics for multiple samples • Simple quantitation by curve fitting with a number of fit algorithms • Intracellular ion analyses
