EP 1494019 A UPAB: 20050207 NOVELTY - To study at least one frozen biological sample (1,2), it is examined during freezing and/or thawing. The sample is examined optically or by crystallizing. The apparatus has a temperature control unit (5) at the sample holder (4) to freeze and/or thaw the sample, and a light source (6) to illuminate it. A photo detector (9) receives reflected, scattered or transmitted light from the sample. USE - The technique is for the examination of deep frozen biological samples, as quality control of the deep freeze preservation. It has applications in the conservation of cells and cell cultures, e.g. stem cells and ovum cells to check their vitality. ADVANTAGE - The method gives a real time examination of the frozen samples, without damage.
