The Alltesta™ Mini UV-Vis Detector is a compact multi-wavelength UV-Vis detector designed for researchers and analysts. It provides reliable, real-time monitoring of the optical properties of flowing liquids and can be integrated into a variety of analytical systems. The detector is suitable for applications including High-Performance Liquid Chromatography (HPLC), Flow Injection Analysis (FIA), preparative and flash chromatography, and other flow-based analytical techniques. The standard configuration includes four wavelength channels: 275 nm (UV), 460 nm (Blue), 520 nm (Green), and 630 nm (Red). Custom configurations are also available, allowing any four wavelengths starting from 255 nm to be factory-selected to meet specific application requirements.

The Alltesta™ Mini UV-Vis Detector features a simple setup with a USB interface for communication with the Alltesta™ Analyzer or integration with other instrumentation. Powered through its USB connection, the detector can monitor up to four wavelengths simultaneously and acquire data at 20 samples per second per channel. Optical flow cells are available in 3 µL and 10 µL configurations. The low-volume flow cell minimizes sample dispersion and helps maintain chromatographic performance, even at low flow rates. The detector uses highly stable LED light sources, providing instant start-up, low power consumption, long operational life, and eliminating the need for routine lamp replacement. A built-in adjustable pressure regulator helps maintain a bubble-free optical path.The detector can also be supplied with an optional analog output module for integration with external data acquisition and analytical systems.
