However, it's worth noting that glacial acetic acid is not without its hazards. It can cause burns upon contact with skin and can be corrosive to certain materials. Thus, safety precautions are essential when handling this substance in both laboratory and industrial settings. The awareness of these hazards is particularly crucial for anyone working with concentrated acetic acid, as improper handling can lead to serious injuries.

In biological research and laboratory settings, glacial acetic acid is commonly used for its properties as a fixative and solvent. It plays a critical role in histology for tissue preservation and staining processes. The acid’s ability to penetrate biological tissues enhances the clarity and detail of microscopic examination, making it invaluable in medical and research laboratories.

One of the primary reasons researchers choose TAE buffer is its buffering capacity, which is influenced by the concentration of acetate ions. Glacial acetic acid serves to provide a robust source of acetate when it is dissolved with Tris and EDTA. The chemical equilibrium between the acetic acid and its anion (acetate) allows TAE buffer to maintain a pH of around 8.0 to 8.5, making it suitable for many applications in nucleic acid manipulation. This pH range is particularly compatible with various enzymes used in molecular cloning and DNA amplification techniques.
