PerkinElmer LAMBDA 750 UV/Vis/NIR Spectrophotometer

The PerkinElmer LAMBDA 750is an instrument ideally suited for chemistry and material science applications, busy academic and industrial laboratories that perform measurement of liquids, gels, and solid materials and need flexibility of sampling along with high measurement performance. It is designed to provide the maximum sampling flexibility for tough samples in chemistry, biochemistry and materials science.Adouble-beam, double-monochromator designof Lambda 750 provides the highest possible stability coupled with the highest accuracy and lowest stray-light performance. Extension of the measurement range into the Near-IR region of the spectrum provides richer and complementary spectral information for many compounds and materials.A choice of cells and sample holders allows virtually any liquid sample to be measured. Options include long-path cells, test-tube holders, flow through cells and micro and semi-micro cells.Powder analysis is easily accomplished using the 60 mm integrating sphere in reflectance measurement mode -raw materials testing, organic and inorganic chemicals, geological and powdered polymers and coatings. Specular, diffuse and total reflectance measurements using the 60 mm integrating sphere, allow rapid analysis of continuous solids such as glass, textiles, polymers and coated surfaces.
