General description

Formaldehyde solution min. 37% free from acid - stabilized with about 10% methanol and calcium carbonate for histology, is used for human-medical cell diagnosis and serves the purpose of the histological fixation of sample material of human origin. An optimal fixation in the pre-analytical phase of the histological process is one of the most important preconditions for ensuring the good preservation status of the tissue in question and of the structures and macromolecules it contains and thus for enabling a precise histopathological analysis of specimen material. When used properly, this fixing solution is optimally suited for this purpose. The product is a concentrated formaldehyde solution min. 37 %, stabilized, corresponding to a so-called "formalin solution 100 %". The term "100 % formalin solution" is a well-established term used in histological circles for solutions of at least 37 % formaldehyde in water. This has historical reasons. Used in conjunction with other in vitro diagnostic products from our portfolio, in the pre-analytical phase of the histological process it serves the purpose of preserving tissue structures and macromolecules, which are of decisive relevance in histopathological analyses. For more details, please see instructions for use (IFU). This product is registered as IVD and CE marked.
