Thermo Scientific™ Paraformaldehyde (96%) is a high-purity, white powdered polymer of formaldehyde used widely in histology, cytology, cell biology, and synthetic resin production. In aqueous solution, paraformaldehyde depolymerizes to yield formaldehyde, a widely used fixative and crosslinking agent.
This reagent is critical in tissue preservation and fixation protocols, especially for light and electron microscopy, where it helps stabilize cellular and subcellular structures. It is also employed in fumigation, disinfection, and as a raw material in the manufacture of melamine, phenol, and polyacetal resins.
Applications
- Preparation of formalin fixatives for histological or cytological samples
- Fixation of cells and tissues in electron microscopy
- Use in synthetic resin production (e.g., melamine and phenol resins)
- Employed as a disinfectant and fumigant
- Crosslinking agent in molecular biology protocols
- Used in cell culture applications
