Well Plate Illuminator

New: PWM Dimmer Module - The WPI now supports an optional Pulse Width Modulation (PWM) dimmer, allowing precise light-intensity control through duty cycle adjustment. Users can fine-tune irradiance without affecting spectral output — ideal for applications such as kinetic studies, photoredox screening, or experiments requiring controlled light exposure. (WPI-VP)

The Luzchem Well Plate Illuminator (WPI) is a high-throughput LED exposure system designed for experiments requiring simultaneous irradiation of multiple samples. The instrument is optimized for use with standard 24-well plates, allowing researchers to perform parallel experiments with consistent and reproducible illumination conditions.

The WPI uses 24 high-quality LEDs, one dedicated to each well, to provide uniform illumination across the entire plate while minimizing cross-exposure between neighboring samples. Each LED is paired with a custom optical guide and lens that directs light precisely into its corresponding well, ensuring consistent irradiance across all sample positions.

The system is designed for illumination from below, enabling efficient light delivery through transparent well plates or vials. In addition to standard well plates, 4 mL auto-sampler vials can be placed inside a well plate to allow flexible sample handling for photochemical experiments.

The WPI features a compact anodized aluminum body that helps dissipate heat generated by the LEDs, while an integrated cooling fan maintains stable operating temperatures during extended experiments. 

The instrument is available with a range of LED wavelengths across the UV and visible spectrum, allowing researchers to select the illumination best suited to their applications. Typical wavelengths include UV (~403 nm), blue, green, red, far-red, and white LEDs, all with fully characterized spectral output.

The system includes LED-blocking safety glasses as standard and can be paired with optional light shields to further improve safety when working with high-energy LED wavelengths.

Two optional shields are also available - one for use with well plates and another used for vials.
