The UV-4570 is only 6 inches wide (15cm) 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

Optional flow cells

Micro, preparative and high-pressure

The UV-4070 (190 – 900nm)  and UV-4075 (190 – 700nm) UV-visible HPLC detectors both use 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.

Optional flow cells

Semi-micro, semi-micro SP (UHPLC), preparative and high pressure for SFC

Spectral Scanning and Dual Wavelength Detection

Both detectors include dual-wavelength data acquisition (up to 100Hz for UHPLC) and spectral scanning. Spectral scanning can be executed automatically in ChromNAV CDS, by time or by height when a peak exceeds a set threshold.

Easy User Maintenance

User maintenance can be done without removing the module from the system. Light source replacement is made through the front panel and automatic wavelength calibration can be carried out using a mercury lamp.

Operation as a Stand-Alone Instrument

The UV-4000 series detectors have a keypad for direct control, parameters can be easily changed and operated in a time program for control throughout a separation (this can be be triggered using a TTL pulse or contact closure). A simple RS232 protocol can be used for control through third part programs.
