UV/Vis Detector 詳細資訊 *
UV/Vis Detector S 4245 and S 4250

The UV/Vis - Detektors S 4245 und S 4250 are variable wavelength UV/Vis detectors for routine analysis and sophisticated research.

The dual lamp design offers a wavelength range of 190 – 900 nm with a low baseline noise.

The front - accessible flow cell can easily be exchanged, as can be the lamps which are accessible through a side panel in the instrument housing.
