Used PERKIN ELMER Lambda 20 #146018 for sale

PERKIN ELMER Lambda 20 Spectrophotometer is an advanced optical instrument designed to measure absorptions in the ultraviolet and visible radiant energy spectrum. It uses cutting-edge technology to provide accurate analysis of the properties of compounds by monitoring their absorption of ultraviolet or visible light. This allows for precise determination of the optical properties of sample solutions or solids. Lambda 20 utilizes a monochromator for spectral selection, ensuring that the sample is illuminated accurately and efficiently. The total spectrum of the light is divided into individual wavelengths, allowing for the selection of specific characteristics of the spectrum to be studied. The light is then collimated by a mechanical shutter and directed through a loading chamber, which houses the sample solution. The sample is then divided into two parts by a beam-splitter, and a detector array is used to measure the intensity of the light at each wavelength. As the sample absorbs the light, its absorbance is calculated using the measured intensity-wavelength relationship. The absorbance measured is matched to a specific wavelength, allowing for the analysis of a wide variety of sample solutions. PERKIN ELMER Lambda 20 is also built with a temperature-controlled sample compartment, allowing for optimal accuracy during analysis. The instrument is also equipped with a built-in video system, allowing for easy sample view under the hood. Lambda 20 is a state-of-the-art spectrophotometer that offers superior accuracy in the analysis of sample compounds. Its high sensitivity and accuracy are proven to provide reliable results that support a wide range of applications, including medical research, food analysis, and environmental monitoring.
