Mini UV-Vis Detector

SIELC offers a Mini UV-Vis Multi-wavelength Flow Through Detector

SIELC’s mini Alltesta™ UV-Vis Multi-wavelength Detector can continuously monitor the optical characteristics of the solution flowing through it. This mini device can be utilized for HPLC, Flow Injection Analysis (FIA), and preparative & flash chromatography.

It offers a very simple setup with a USB interface to communicate with our Alltesta™ Power Tower or integrate with other instrumentation. Our cloud-based monitoring and data-handling software make this compact detector unparalleled to all existing detectors.

In addition, the USB port provides all the power needed for this mini detector – no additional power cable is needed. A selection of 4 different wavelengths across the visible spectrum allows users to monitor several different analytes at the same time. A low optical cell volume (<3 µL) provides very little dispersion to even small flow rate applications. The data collection rate can reach up to 20 sps for 4 channels, which is sufficient for even the most demanding applications. Low noise and more than 4 orders of magnitude linearity is standard.

Cloud-based software for operation, data storage, peak integration and quantitation is available via Alltesta™ Power Tower.

Our compact detector has zero warm-up time and a very high durability. The detector cell volume comes in two sizes: 3 μL and 10 μL.
