Alltesta™ Mini UV-Vis Detector
The Alltesta™ Mini UV-Vis Detector is designed with researchers and analysts in mind. This compact yet highly capable device provides accurate, real-time monitoring of the optical properties in flowing solutions. The detector is engineered to operate in various laboratory applications, including High-Performance Liquid Chromatography (HPLC), Flow Injection Analysis (FIA), preparative and flash chromatography and many more.
The device comes standard with four different wavelength channels, including 470 nm (Blue), 520 nm (Green), 630 nm (Red), and a choice between 255 nm or 275 nm for the UV channel. Powered solely by its USB port, this detector is capable of monitoring up to four different wavelengths simultaneously.
The Alltesta™ Mini UV-Vis Detector features a simple setup process with a USB interface that allows it to communicate with the Alltesta™ Analyzer or integrate with other instrumentation. It has a low optical cell volume of <3 µL, which results in minimal dispersion even at low flow rates, and can collect data at rates 20 sps for each optical channel, making it suitable for demanding applications.
In addition to its compact size and versatility, the Mini Detector also has zero warm-up time and exceptional light source durability. It never needs to change the UV source while in most other detectors the UV lamp requires to be replaced every 2000 hrs of the operation. The detector can be supplied with an optional connector which provides an analog signal output.
