Description

Product Information

The Thermo Dionex ICS-Series VWD Variable Wavelength Detector, model 70220, is a reliable instrument designed specifically for routine ion chromatography applications. This used detector offers outstanding sensitivity and accuracy with a wavelength range of 190 to 900 nm and dual-lamp capability combining Tungsten and Deuterium lamps. It operates efficiently without concern for metal contamination, as it supports Thermo Scientific PEEK flow cells, excluded in this listing. The detector features a variable wavelength type, collecting data at rates up to 10 Hz, and has low drift and noise levels. This unit, originally manufactured in the United States, is in very good condition, functional with minor cosmetic damage, and passes all function tests. It’s powered by a versatile voltage range of 120V/220V and frequency range of 50Hz/60Hz. Please note that this system is standalone and could be integrated into larger setups, provided with a power cord but excluding computer and software components. Purchasers can buy with confidence knowing its functionality supports warranty compliance.
