Used WATERS 2487 #136263 for sale

WATERS 2487 is a dual wavelength spectrophotometer manufactured by WATERS Corporation. It is designed to measure absorbance and fluorescence in the ultraviolet and visible spectral range. The spectrometer is suited for a wide range of analytical applications in the laboratory, including colorimetric assays, nucleic acid and protein quantitation, and the analysis of trace contaminants. 2487 is equipped with a quartz tungsten halogen (QTH) lamp for absorbance measurements in the UV/Vis range. A xenon flash lamp is used for fluorescence measurements. The spectrometer uses two monochromators to control the light source, each equipped with a holographic grating and variable slits. The grating is motor-driven and provides dispersion power up to 0.5nm over a wavelength range of 220 - 1000nm. The slits enable a variety of scan speed/bandwidth settings to accommodate different sample types and applications. The detector is an R928 photomultiplier tube, which is protected from stray light by a baffle design. This enables high-sensitivity measurements for both absorbance and fluorescence. The dynamo amplifier is used to monitor changes in light intensity, providing a fast response time for flow cell analyses. WATERS 2487 can be configured with either a Peltier-cooled or room-temperature dark chamber. The dark chamber reduces background signal and allows for greater precision in light measurement. A single cell holder or combinatorial flow cell holder can also be used to accommodate multiple sample types. The instrument is equipped with a microprocessor-controlled keyboard and display. The user-friendly interface allows fast and accurate operation of the spectrometer, as well as adjustment of parameters such as sensitivity, scan speed, gain, wavelength shift, and baselines. 2487 is a reliable, high-performance spectrophotometer with a small footprint. The combination of precise optics and user-friendly interface makes WATERS 2487 a versatile and cost-effective solution for a wide range of applications.
