ABSTRACT:
The invention provides for tissue fixation by subjecting the tissue to the vapor of a fixative while the tissue is unstressed. The tissue may be rotated during fixation to avoid collecting condensed fixative at localized areas of the tissue. Intermittent rinsing of the tissue during fixation is possible. The concentration of fixative in the vapor may be varied, increasing after an initial period. Specific rinsing and fixative solutions are disclosed.
