Used WATERS 470 #9079714 for sale

WATERS 470 is an advanced UV-visible spectrophotometer manufactured by WATERS Corporation, allowing users to measure the absorbance of light by a sample in the visible and near infrared range of 200 to 900 nanometres (nm). This device is a double beam instrument, operating by the use of two monochromator beam-splitters to separate the sample and reference beam. The light is then filtered and directed towards a photomultiplier tube, which produces a current proportional to the incident light. When the sample passes through the optical system, a change in absorbance is registered and recorded in the detector as the ratio of transmitted light to the incident light. The instrument is enclosed in a metal case with an LCD display providing important information such as sample path length, wavelengths, energy calibration, instrument range, peak resolution, concentration limit, etc. It also includes a sample compartment with five sample cells, which are suitable for samples with an absorbance of less than 0.3 absorbance units (AU). The software used for 470 spectrophotometer includes multiple user-friendly tools for both users and operator control, enabling easy examination of spectral scans and data processing. With the data acquisition and processing features, users can store and process an unlimited number of spectral scans. Additionally, the software includes sample library functionality, making it suitable for multi-sample data acquisition and comparison. In terms of performance, the device has a wavelength accuracy of 1/nm and a spectral resolution of 0.1nm. The limit of detection for absorbance is 0.001 AU while the range of absorbance reading can go up to 3 AU. With an additional accessory, WATERS 470 spectrophotometer is able to attain molar absorptivity values and Beer-Lambert linearity. Overall, 470 spectrophotometer is a versatile instrument, ideal for a variety of applications such as protein and nucleic acid quantification, quality-control standardization, as well as cell and tissue analysis. With its easy-to-use software and adjustable parameters, the device is capable of providing reliable results and making a valuable contribution in research and industrial laboratories all over the world.
