Used PERKIN ELMER Lambda 900 #293818729 for sale

PERKIN ELMER Lambda 900 spectrophotometer is a valuable tool for detecting and measuring light absorption and intensity in a wide range of applications. By utilizing an automated monochromator, Lambda 900 measures absorbance over a variety of wavelengths, making it ideal for use in optoelectronic, biochemical, and environmental research. The spectrophotometer uses a double-beam optical assembly to collect both the sample and reference light beams. These beams pass through a monochromator to select the desired wavelengths, then through a sample and reference cell, which are housed in a temperature-controlled cuvette holder. The sample cell contains the fluid specimens, while the reference cell holds deionized water, which serves as a baseline or zero absorbance point against which the sample absorbance is compared. Both the sample and reference beams travel in paths equal in length to eliminate any interference or errors caused by any differences in their paths. A detector measures the difference between the sample and reference beams, and the results are displayed as absorbance units or in terms of concentration when using the built-in equations. PERKIN ELMER Lambda 900 has many features that make it a versatile and user-friendly tool for research and industry. The cuvette holder is able to accommodate a wide range of sample sizes, and features a temperature-control system to keep the samples at an optimal temperature. The computer interface allows for quick and easy data entry and access to a plethora of options and functions, while the built-in equations make it possible to express the absorbance results in terms of concentration of sample. In addition, the software is capable of making various modifications to the data, such as baseline correction and data smoothing. Overall, Lambda 900 spectrophotometer is a reliable and robust instrument that can accurately and quickly measure light absorption and intensity in a variety of applications. Its user-friendly interface, comprehensive functions, and wide range of features make it ideal for any laboratory environment.
