Method and arrangement for investigation of biological materials

摘要

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.
