Double Beam UV-Vis Spectrophotometer US-B15

The UV-Visible Spectrophotometer US-B15 is a highly sensitive double beam spectrophotometer designed for the wavelength range of 190 to 1100 nm, enabling the measurement of absorbance spectra of chemical and biochemical compounds. With a bandwidth of 2 nm for peak resolution, it effectively detects light intensity differences between the reference and test samples. The instrument utilizes highly stable optics and a silicon photodiode detector to simultaneously measure the sample and reference, optimizing measurement accuracy. Additionally, it features a built-in ARM system for high accuracy and stability.
