Many biological samples require cooled storage during processing to avoid deterioration. Therefore, many autosamplers offer cooling, but very few autosamplers offer adequate cooling across the entire sample space. Some of our autosamplers not only offer cooling, but also offer sample temperature control from 4°C up to 40°C for the entire sample tray and sample processing space. Actual readout of tray temperature shows when the autosampler is ready to accept new samples. Actual tray temperature can also be linked to sample assay results to verify correct sample temperature afterwards. And, in addition, the cooling device has been designed to reduce condensation in the sample area to a minimum.
Elevated sample temperature improves sample solubility and thus helps to prevent precipitation of poorly soluble analytes and adsorption of analyte to vial walls.
