Used PERKIN ELMER / BECKMAN COULTER DU-50 #9254220 for sale

PERKIN ELMER / BECKMAN COULTER DU-50 is a double-beam UV/Visible spectrometer that is capable of providing measurements of absorption, emission, reflectance, fluorescence, and other optical spectroscopic techniques. The device is designed with an intuitive graphical user interface which allows for quick and accurate data acquisition and manipulation. PERKIN ELMER DU-50 employs a motorized scanning mechanism which can travel over a wide range of wavelengths. The scan rate is adjustable and ranges from 0.15 nm/s to 9 nm/s. The double-beam design allowing for high sensitivity and excellent signal-to-noise ratios. The device features a wavelength accuracy of ± 0.2 nm and a bandwidth of 0.7 nm. BECKMAN COULTER DU-50 is designed with a sample compartment and a light source that is capable of providing a wavelength range between 200 and 1050 nm. The maximum photocurrent is 280 μA. The detection range of the device is capable of measure absorbance values between 0.0000 and 2.0000 A. DU-50 comes equipped with two sample cells which allows for comparative measurements and/or sequential measurements without the need to manually switch cell holders. PERKIN ELMER / BECKMAN COULTER DU-50 is also designed with standards for emission measurements. The device has a built-in xenon lamp with an adjustable power switch from relative intensities to 10 W. The UV-Vis spectrometer also contains an optional internal shutter to control light output which is ideal for both short and long exposure. PERKIN ELMER DU-50 can be controlled remotely using the RS232 protocol and features software packages for automatic data scanning and collection. Additional accessories are also available, including sample holders and positions, weighing scales, integrated PCs, and fiber optic cables. The device can be relied upon to provide accurate and reliable spectroscopic data which is critical for accurate chemical or process analysis.
