Agilent 1260 Infinity VWD Detector (G1314B) (Refurbished)

The Agilent 1260 Infinity Variable Wavelength Detector (VWD) G1314B is a high-performance detector designed for liquid chromatography (HPLC) applications. Renowned for its reliability, the detector offers precise detection of analytes across a wavelength range of 190 to 600 nm. Its double-beam photometer configuration ensures high accuracy and sensitivity, making it an indispensable tool in HPLC laboratories. The system incorporates a deuterium lamp for consistent UV light intensity, providing stable and reproducible results. Designed with user convenience in mind, the G1314B features easy front access for lamp and flow cell replacements, as well as a built-in holmium oxide filter for wavelength accuracy verification. This detector is compatible with Agilent ChemStation software for seamless data analysis and offers extensive diagnostics and safety features, making it suitable for Good Laboratory Practice (GLP) environments.
