Spectro Q


is a highly sophisticated and trend-setting combined imaging and dynamic light scattering (DLS) plate hotel system. The fully automated DLS capability extends the application spectrum of the system far beyond the state-of-the-art imaging systems. Usually, hotel systems are dedicated imagers and can be used exclusively for imaging purposes, mainly for protein crystal finding and identification. In contrast, SpectroQ enables the very fundamental DLS analytics in combination with the fully automated hotel, providing a new application field for hotel systems in general. Because of that, it can be applied to a variety of applications including analysis of samples during preparation and quality evaluation. These capabilities are therefore not just providing a more comfortable workflow at the very last step of imaging crystals but provide new and highly advanced analytical possibilities.

Automated Plate Imaging

The SpectroQ combines storage and processing of samples in standard crystallization plates under temperature-controlled conditions. Plate processing comprises two major functions, imaging and dynamic light scattering (DLS).
