ABOUT THIS PRODUCT:
The Visible Spectrophotometer enables quantitative and qualitative analysis of samples within the visible spectrum and is a great value in a precise, accurate, compact design. Featuring a large, easy to read digital display, visible wavelength range of 340 -1020 nm, 5 nm bandpass, Four modes: T = transmittance, A = absorbance, C =concentration & F = factor, auto-zero function, and a sample compartment that accepts square cuvettes (4 square optical glass cuvettes included as well as a user manual). It can be widely used in the classroom to analyze biotech and chemical properties of many different materials.
