AZURA UV Detector UVD 2.1S Fiber Optics

AZURA UV Detector UVD 2.1S Fiber Optics

Manufacturer: KNAUER
GMI SKU#: 8206-10-0014

190 - 500 nm, small variable single wavelength UV detector with fiber optics connectors

For more information or to place an offline order call 1-800-745-2710


The AZURA UVD 2.1S is a highly competitive single variable wavelength UV detector for HPLC.  It offers excellent technical specifications for routine laboratory work. With its small footprint, it is one of the smallest detectors for HPLC on the market.

The UVD 2.1S comes in the novel small AZURA housing. The installed deuterium lamp covers a wavelength range from 190 to 500 nm. The UV detector can be controlled with OpenLab® EZChrom Edition, ChromGate®, PurityChrom Bio and ClarityChrom® software, as well as from the front panel (stand-alone operation), via LAN, via RS-232, or through analog input/output; allowing it to be integrated into almost any LC system.

Due to a smart design the flow cell is easily accessible and can be changed very quickly. You can choose between a wide range of flow cells for analytical or preparative LC applications with flow rates from 10 ?l/min up to 10 l/min.

This fiber optics version offers the possibility to separate the flow cell spatially from the device and thus provides enhanced security for hazardous, explosive or toxic work processes.
