Description
Overview
GAOTek UV Spectrum Analyzers have been widely used in colleges and enterprises for general quantitative analysis and experiments based on absorbance measurements.
Features
● High quality silicon photometric diode detector and 1200 lines/mm diffraction grating ensure the high-quality accuracy and precision
● Backlit LCD display for an easy readout
● Automatic 0A and 100%T. Easy switching of transmittance, absorbance and concentration modes, just by pressing one key
● Direct concentration read-out and concentration factor setting function
● Large sample compartment, which can accommodate 5mm to 100mm path length cuvettes with optional holders
● Easy to change the halogen lamp or deuterium lamp by the user himself
