The LS-55 And LS-45 Fluorescence Spectrometers Perkin Elmer USA

The LS-55 and LS-45 Fluorescence Spectrometers Application: Fluorescence spectrometer that can be configured with software and accessories to address a wide range of application requirements. Description: Versatile, computer controlled Fluorescence spectrometer; incorporates a 8.3 watt, pulsed xenon source for fluorescence and phosphorescence decay time measurements. Excitation 200# 800 nm and emission 200# 900 nm with zero order selectable. Standard PMT covers 200# 650 nm; R928 or R955 PMT optionally available for full range. Synchronous scanning with constant wavelength or frequency difference included. Excitation spectra are automatically corrected. Uses holographic excitation grating for reduced stray light levels. Variable excitation 2.5# 15 nm and emission 2.5-20 nm slits in 0.1 nm increments. Scan speeds can be selected in 1 nm increments from 10-1500 nm/ minute. Includes Single-position, water-thermostatted cell holder and Septum injector Incorporates a software-controlled filter wheel in the emission monochromator with 290, 350, 390, 430 and 515 nm cutoff filters, 1% T attenuator and clear beam. Includes automated polarization accessory that consists of 2 filter wheels; each wheel containing a horizontal and vertical polarizing element. Polarizer positions are software controlled and can be manually set or automatically controlled for polarization, anisotropy or G-factor Includes sample compartment purge nipple to allow dry air or nitrogen to be blown into the sample area to prevent the optics fogging for low temperature applications. FL WinLabÔ Software Package, WindowsÒ based software controls the instrument, sampling accessories and data collection. The software provides specific applications such as Scan, Time Drive, Ratio Data Collection, ICBC Calibration, Well Plate Reader and 3D view. 1V and 10 mV analog output.
