OPTIZEN Alpha UV-VIS Spectrophotometer

The UV-VIS Spectrophotometer – Double Beam – OPTIZEN Alpha by K-Lab delivers high-precision measurements for accurate laboratory analysis. Available through Apex Scientific in South Africa, this advanced laboratory equipment measures transmittance and absorbance across ultraviolet and visible wavelengths. Consequently, researchers can perform quantitative assessments, such as concentration and purity, with consistent reliability in demanding research environments.

Accurate Measurements

The OPTIZEN Alpha uses a double-beam method that reduces errors common in single-beam spectrophotometers. Moreover, the reference beam compensates for light intensity fluctuations. As a result, it provides reliable and reproducible results. This feature supports precise quantitative analysis in biotechnology, environmental science, chemistry, and other applications where accuracy is critical.

Versatile Applications

This spectrophotometer suits a wide range of tasks. For instance, it measures DNA concentrations, evaluates chemical purity, and monitors other key parameters. Its broad wavelength range and high-resolution capability allow scientists to obtain trustworthy data consistently. Therefore, it is ideal for laboratories requiring both versatility and accuracy.

User-Friendly Features

K-Lab designed the OPTIZEN Alpha for convenience. The integrated interface allows fast operation and quick data acquisition. Additionally, its advanced software performs analyses up to 1.5 times faster than previous models. The compact design also maximizes workspace efficiency. Furthermore, intuitive controls reduce user error and simplify experiment management.

Overall, the UV-VIS Spectrophotometer – Double Beam – OPTIZEN Alpha remains a trusted choice for laboratories in South Africa. It ensures reliable performance across diverse scientific applications.
