Almost twice as accurate as other educational grade spectrophotometers, the Sargent-Welch Educational Spectrophotometer will easily do Beer-Lambert, Absorption Spectrum, Chlorophyll, protein (burette test) experiments, and more. 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. The large digital display makes reading much easier, and the analog interface allows you to collect data easily with an external analog device. The Sargent-Welch Educational Spectrophotometer comes with a 1/2 inch round tube holder, a box of 12 round glass test tubes, a 10mm square curvette adapter, dust cover, and a user's manual.
