Product Description
The Double Beam UV-Vis Spectrophotometer, available in models YG0899, YG0900, and YG0901, sets a new standard in laboratory spectrophotometry with its precise double beam optical system. Equipped with a 1200 lines/mm grating, it offers a wavelength range of 190-1100nm, making it versatile for a myriad of applications in research and industrial settings.
Key technical specifications include a wavelength accuracy of ±0.1nm at D2 656.1nm, bandwidth variations of 1.8nm, 1.0nm, and customizable options in the YG0901 model (0.5, 1.0, 2.0, 4.0 nm). This level of flexibility ensures that users can adapt the spectrophotometer to specific analytical procedures, whether they require narrow or wide bandwidths.
Additional features such as photometric accuracy of ±0.2%T, photometric repeatability of ≤0.1%T, and a photometric range that spans -0.3-3A, 0-200%T, and 0-9999C, guarantee that this spectrophotometer meets stringent laboratory requirements. Its stability is evidenced by a minimal deviation of ±0.0003A/h at 500nm, and a pristine baseline flatness of ±0.001A/h further enhances its analytical precision.
The spectrophotometer includes advanced data management capabilities with a USB data output port and a parallel printer port. Display features include a 320*240 dots LCD for easy readout. Illumination is provided by a tungsten lamp and a deuterium lamp, paired with a reliable silicon photodiode detector. Designed for usability, the device supports power requirements of AC 220V/50Hz or AC 110V/60Hz, fitting into most standard laboratory electrical setups with ease.
