| 摘要 |
The invention relates to a method and to a device for preparing biological samples by means of a series of different liquids containing preparation agents in a chamber (10) which comprises a first and a second opening (12, 14) for introducing the liquids into the chamber (10) and removing them therefrom. When the liquid which is to be introduced into the chamber (10) has a density less than the liquid in the chamber (10), said chamber (10) is placed in a first position wherein the first opening (12) is located above the second opening (14). When the liquid which is to be introduced into the chamber (10) has a higher density than the liquid in the chamber (10), the chamber (10) is placed in a second position wherein the first opening (12) is located below the second opening (14).
