Formalin-acetone fixative mixture is a carefully formulated solution valued for its use in histology, medical diagnostics and scientific laboratories. It consists of acetone (CH3COCH3), propionaldehyde (CH3CH2CHO), formaldehyde (CH2O) and propylene glycol (C3H8O2), which are matched to provide optimal fixation and preservation of tissue specimens. Formaldehyde acts as a strong fixative, while acetone and propionaldehyde contribute to dehydration and further fixation of tissue structures. Propylene glycol acts as a stabilizer and creates ideal conditions for the chemical reactions.

By using this mixture, detailed images of cells and tissues can be obtained, which is of great importance for the diagnosis of diseases. In addition, its components make it suitable for a variety of specific applications.
