Abstract
A method and an arrangement for preparing a biological specimen (20), where the biological specimen (20), prior to being examined in e.g. a microscope, is dried, embedded in wax and optionally sliced, and where the biological specimen (20) is placed in a container (1) with a lid/clamping member (2) that is closed, in which it is retained by a biasing element (6), the specimen (20) remaining in the same closed container/lid (1, 2) during the subsequent drying and embedment operations, whereupon the container (1) is removed from the lid (2) and the specimen (20) prior to any slicing operations.
Claims7
A biological specimen container, comprising:
- a container body having side walls, a bottom, and an inner bottom surface, where at least one of the container side walls includes a projected bead;
- a container lid having an inner lid surface, the container lid including at least one groove corresponding to the projected bead such that the container lid is structured to lock to the specimen container;
- and
- a plurality of biasing elements coupled to the inner lid surface of the lid and configured to apply a retaining force to a biological specimen toward the inner bottom surface of the container body when the lid is fitted to the container body, each of the plurality of biasing elements including a hair-like spring having a first end attached to the inner lid surface of the lid, wherein each biasing element extends substantially perpendicularly from the inner lid surface to a second end.
