Article No.: EDA03XA
Articlename: AZURA UV Detector UVD 2.1S for ASM 2.2L

Compact variable single wavelength UV detector for ASM 2.2L

UV detector UVD 2.1S - EDA03XA

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 a small housing. The installed deuterium lamp covers a wavelength range from 190 to 500 nm. The UV detector can be controlled with OpenLab EZChrom Edition®, Chromeleon®, PurityChrom®, Mobile Control® and ClarityChrom® software via LAN, as well as 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 μl/min up to 10 l/min.
EDA03XA is the article number for a module integrated in the assistant. To order the device separately use ADA03XA.
