Description

technical field [0001] The invention relates to laboratory automation equipment, in particular to a fully automatic solution dialysis experiment device. Background technique [0002] Dialysis technology refers to a separation and purification technology that separates small molecules from large molecules through the principle of small molecules diffusing into water (or buffer) through a semi-permeable membrane. Solvents, small biomolecules and other impurities and concentrated samples and other purposes. [0003] At present, dialysis instruments (such as hemodialysis) are widely used in medical and health services. They use the principle of semi-permeable membranes to remove various harmful and redundant metabolic wastes and excess electrolytes in the fluid to purify the blood. However, in the process of scientific experiments, for other laboratory batches of liquid phase samples (such as dialysis of natural organic matter solutions, etc.), there is no automatic instrument ...
