NAWASHIN’s Fixative

Nawashin fixing mixture is a fixing solution mainly used in botany, especially for fixing plant tissue to preserve its morphology and cellular structures. The solution consists of the essential components chromium(VI) oxide, acetic acid (99%) and stabilized formaldehyde (37%).

The combination of these components provides good fixation and preservation of cellular structures in plant tissues, making them suitable for microscopic studies and histological staining. Chromium(VI) oxide contributes to the fixation of cellular structures, while acetic acid and formaldehyde provide additional fixation and preservation.

In pathology and zoology, the use of this fixative solution is less common because there are alternative fixative solutions that are more suitable for the study of animal tissue. However, it can be used in special cases when fixation of plant tissue is required in pathology, such as in the study of plant pathogens or plant-animal interactions.
