Scanning UV-Visible Spectrophotometers

Features

✧ With the sample temperature control system, the sample temperature can be controlled between -5℃~200℃;
✧ The light source correction mechanism will enable the instrument to position the light source to the best position during self-test. This function can repair the deviation of the focus position of the light source due to vibration during transportation of the instrument. Users do not need to debug after replacing the light source themselves;
✧ The optical system design and circuit control system design are rigorous, and the selection and selection of components are strictly controlled. This instrument has high standards of accuracy, repeatability, low noise and low stray light;
✧ The open sample chamber can be equipped with optional reflection sample racks, automatic 5-link, 6-link, and 8-link sample cell racks, solid sample racks, constant temperature water baths, and automatic samplers.
