The UV-4570 is only 6 inches wide（15 cm）and can be used stand-alone or as part of a system for single wavelength measurement from the UV to Visible region（190-900 nm）with cassette-type tapered flow cells and user-replaceable lamps. Programmable wavelength switching and spectral scanning.

The UV-4070 (190 – 900 nm) UV-visible HPLC detector uses an advanced Czerny-Turner monochromator with dual wavelength and scanning functions. Baseline change due to refractive index is minimized by the flow cell design, and fluctuation from changes in environmental and lamp temperature are reduced with a regulated lamp housing and temperature controlled cell.

The UV-4075 (190 – 700 nm) UV-visible HPLC detector uses an advanced Czerny-Turner monochromator with dual wavelength and scanning functions. Baseline change due to refractive index is minimized by the flow cell design, and fluctuation from changes in environmental and lamp temperature are reduced with a regulated lamp housing and temperature controlled cell.
