KNAUER AZURA MWD 2.1L Multiwavelength Detector

The KNAUER AZURA® MWD 2.1L is a sensitive 8-channel UV/VIS multiwavelength detector designed for analytical, semi-preparative, and preparative liquid chromatography. Combining excellent performance, user-friendly operation, and affordability, it provides a versatile solution for routine and advanced LC applications.

The detector features a newly developed optical unit and intelligent temperature management to ensure maximum sensitivity with minimal baseline drift. Optional LightGuide flow cells based on total internal reflection technology maximize light throughput and minimize peak dispersion, resulting in an optimized signal-to-noise ratio. An optional fiber-optic adapter allows physical separation of the flow cell from the detector, increasing safety when handling hazardous, explosive, or toxic materials.

The AZURA® MWD 2.1L can also be upgraded to a full AZURA® DAD 2.1L diode array detector, protecting future investments and enabling greater analytical flexibility.
