Biolab BSDBU-203-B Double Beam UV-Visible Spectrophotometer

The Biolab BSDBU-203-B is a high-precision double beam UV-Visible spectrophotometer designed for advanced analytical and research applications. Engineered with a long 520 mm optical path and 16 mm thick die-cast aluminum base, it ensures exceptional wavelength resolution, accuracy, and stability for dependable performance in laboratories.

This model offers a wavelength range of 190–1100 nm with 1 nm spectral bandwidth, supporting a variety of tests including spectrum scanning, kinetics, multi-wavelength, standard curve, and DNA/Protein analysis. The 6-inch high-definition LCD display allows clear visualization of spectra and data directly on the device, while powerful PC software enhances data processing and control.

With USB and parallel ports, data transfer and printing are seamless. The one-button auto-calibration system maintains instrument precision by automatically calibrating baseline, wavelength, and dark current.
