Technology

Is a high throughput screening (HTS) photoreactor designed to speed up the discovery and validation of photocatalysts, e.g. for CO₂ valorization. Compared to a manual assay (1 photocatalyst) our reactor allows to perform «N» assays at a time. PCT/ES2024/070188

The problem of homogeneous Illumination

In an HTS photoreactor it is difficult to illuminate two samples with exactly the same amount of light thus decreasing the reproducibility of the results (A). This problem scales with the number of samples (B). In addition, samples closer to the light source may screen the light received by samples farther away (C).

Our Solution

In PhotoSpinner the specimen array is radially symmetric and its position is not fixed. The samples describe the same periodic and circular trajectory with respect to the fixed lateral light source (A). In this way, the irradiated area is maximized and, for sufficiently long irradiation times, the average distance (and, therefore, the received intensity) for each of them will be the same.

The homogeneity of the irradiation is further enhanced by the individual shaking of each sample (B).

Our design ensures that all samples receive the same amount of validating light.

PhotoSpinner illuminates samples laterally to maximize the irradiated sample area.

Moreover, its axial geometry allows to quickly mount more thn one lamp at the same time.

Photospinner design is adapted for the use of reaction vessels of any size and shape (vials, cuvette, bottles…).

The presence of individual agitation for each of the samples makes it especially designed for the testing of heterogeneous catalysts.

Its design permits the use of gas reservoirs.

Its temperature control module allows reactions to be carried out at a constant and controlled temperature.
