OPTIZEN Alpha is a spectrophotometer that uses a double-beam method.
OPTIZEN Alpha can measure the transmittance or absorbance at each wavelength of a sample in ultraviolet and visible light bands to determine the quantitative characteristics such as concentration and purity.
OPTIZEN Alpha, which can be used widely from general analytical experiments to professional research fields, guarantees accurate measurement and excellent reproducibility and provides reliable results in various fields such as the environment, biotechnology, and chemistry.
The previous single beam type spectrophotometer has a weak point of error occurrence in measuring a sample, because of the movement of a light source by time lag in measuring the strength of between a reference light and a light from sample. To solve the problem, OPTIZEN Alpha was designed as a double-beam type spectrophotometer. The system utilizes an additional reference beam to improve the measurement performance by compensating the intensity fluctuation of its light source.
