Knauer Smartline 2520 UV Detector
€ 3.200,00 excl. tax
Wavelength range 190-750 nm
The beam guidance is designed so that no chromatic aberration occurs and thus the best possible useful signal is available, independent of the selected wavelength.
Automatic recording and storage of the device-specific characteristics that are important for GLP (Good Laboratory Practice), OQ (Operation Qualification) and for the device service and device history.
Self-running and up-to-date device status diagnostics.
Control with chromatography software possible.
Easy integration of the detector into complex chromatography systems.
High data rates for fast chromatography.
Flexible options for use in the entire field of LC applications due to a comprehensive range of flow cells for the detectors, from nano HPLC cells with flow rates ≈ 100 nl/min to preparative flow cells with 10 l/min.
