The Unico S1000 Visible Spectrophotometer comes complete with 10 mm test tube cuvettes (box of 12), 10 mm square cuvette adapter, USB port, dust cover, and user manual. The S1000 is precisely designed and ruggedly built. This easy-to-use spectrophotometer is ideal for student use in high schools, colleges, and for general laboratory testing. It is suitable for general analysis and experiments such as Beer-Lambert, absorption spectrum, chlorophyll, protein (Biuret test), and more. Includes a visible wavelength spectrum chart on the instrument panel, allowing the user to make the correlation between a wavelength number to an actual color on the visible light spectrum. A versatile instrument designed to accept both round optical glass or square 10 mm path length cuvettes. The built-in secondary filters reduce stray light and increase precision. The "student-proof" positive safety stopper integrated with the wavelength dial prevents damage to the monochromator and grating. Large digital display makes reading much easier, and USB interface allows customers to collect data easily. Unico S1000 Visible Spectrophotometer Specifications: Bandpass (Slit Width): 20 nm.
