Formalin 2 %, unbuffered, stabilized
Formalin 2%, unbuffered, stabilized, is an aqueous solution of formaldehyde (formula: CH2O), which is used especially in histology and in vitro diagnostics. The incorporation of this strong aldehyde enables chemical reactions with biological molecules and forms covalent bonds, which contributes to the stabilization of these molecules. Therefore, the product is particularly suitable for fixing and preserving tissues for microscopic studies.
In scientific laboratories, due to its stability, it can be used for a variety of analyses and experiments. Results can vary depending on the specific application, including preservation and highlighting of cell structures to quantification of specific molecules.
Calculation of the molarity of the solution gives an approximate value of 1.68 M for formaldehyde, while the osmolarity is approximately 3.36 Osm. Due to the unbuffered nature of the product, no buffering capacity exists.

Instructions / Protocol / Recommendations
Verwendung:
Bei der Fixierung werden alle in der Zelle ablaufenden Prozesse unterbrochen, unter möglichst optimaler Erhaltung des Zustandes und der Struktur des Gewebes. Biochemische Prozesse wie Autolyse, Verwesung und Fäulnis werden wirkungsvoll verhindert. Fixierlösung nach Stieve eignet sich zur Fixierung von Hodengewebe und Eierstockgewebe. Die Fixierlösung ist ausschließlich für die professionelle Anwendung als in-vitro Diagnostikum im histologischen Labor vorgesehen.
