Used PERKIN ELMER Lambda 25 #293648099 for sale

PERKIN ELMER Lambda 25 is a double-beam ultraviolet-visible spectrophotometer designed with advanced features for sophisticated research, quality control, and industrial applications. This open-ended instrument is designed to measure absorbance, transmittance, and fluorescence in the UVA, UVB, and visible spectral ranges. It has a deuterium lamp for UV measurements and a tungsten-halogen lamp for visible range measurements, and utilizes a unique optical design to deliver exceptional signal-to-noise and performance not achievable with other spectrophotometers. Lambda 25's design is temperature controlled to ensure a stable operating environment. The instrument is composed of various components such as a xenon flash lamp, monochromator, grating, sample and reference cells, and a detector. Samples are placed in cuvettes, which are inserted into the sample compartment. For fluorescence measurements, the sample can be placed in the fluorescence compartment and excited by the xenon flash lamp. The monochromator and grating work together to disperse the incident light, while the detector measures the intensity of the light being received. When the exposed sample is measured, PERKIN ELMER Lambda 25 uses a series of algorithms to convert the detected signal into quantitative readings that enable measurements of absorbance or transmittance of light at any given wavelength. For example, if the instrument is used to measure the absorbance of a sample in the visible range, an absorbance spectrum is generated to determine the quantitative absorbance at each wavelength across the visible range. The data produced can be processed using the built-in software, allowing the user to easily capture, analyze, and store results. Lambda 25 comes with a range of other features that make it well-suited for a variety of applications. These include a variety of user-friendly controls and a library of external accessories which allow users to customize the instrument to their specific needs. Furthermore, the instrument is ergonomically designed for straightforward operation, making it easy to use even for novice operators. In conclusion, PERKIN ELMER Lambda 25 is a highly reliable and precise spectrophotometer perfectly suited for many applications. Its innovative design, performance capabilities, and various user-friendly features make it an ideal tool for research, quality control, and industrial applications.
