The Luzchem LEDi LED Illuminator is a flexible and compact irradiation system designed for photochemical experiments requiring precise LED illumination. The system combines a stable LED light source with integrated sample mixing and interchangeable sample holders, providing a convenient platform for laboratory irradiation of small volumes.
The standard LEDi bundle includes a multi-colour LED head containing seven high-power LEDs that provide blue, green, red, and white illumination with adjustable intensity. Each colour bank can be independently controlled, allowing researchers to tailor irradiation conditions for specific experimental requirements. Specialized optical lenses focus the LED output onto a spot approximately 0.5 inches in diameter, providing efficient illumination of small samples such as cuvettes or tubes.
The LEDi base incorporates a variable-speed magnetic mixer positioned below the sample holder, allowing continuous mixing during irradiation experiments. The standard bundle configuration includes a cuvette holder, which can easily be replaced with optional tube, vial, or NMR-tube holders to accommodate different sample formats. The LED head is mounted on an adjustable rail, enabling precise positioning of the light source relative to the sample.
Air-cooled LED operation minimizes sample heating while maintaining stable illumination conditions, and the system includes safety features such as protective shields and LED safety goggles. A current indicator allows researchers to reproduce experimental conditions by monitoring the current supplied to the LEDs.
A wide range of optional LED heads is available, allowing users to select specific wavelengths across the UV, visible, and near-infrared regions. These interchangeable heads make the LEDi suitable for diverse applications including photochemistry, photobiology, photodegradation studies, photocatalysis, photoredox chemistry, contact imaging, and accelerated aging experiments.
Compact, versatile, and easy to configure, the LEDi provides researchers with a practical LED irradiation platform for a wide range of laboratory experiments.
