Description

Formalin container prefilled with 20 mL of solution is a standardized specimen preservation tool used in histopathology and clinical laboratories. It contains buffered formalin, typically a 10% neutral buffered formaldehyde solution, which serves as a fixative to preserve tissue morphology for subsequent pathological analysis. The prefilled volume is accurately measured to ensure optimal tissue fixation and avoid dilution errors during sample processing.

The container is manufactured from chemically resistant plastic, usually high-density polyethylene or polypropylene, to prevent degradation from the formalin solution. It is tightly sealed with a secure, leak-resistant screw cap to prevent evaporation, spillage, or exposure to toxic vapors.

The 20 mL volume is suitable for small biopsy specimens such as skin punches, endoscopic samples, or minor excisions. The buffered formulation maintains a stable pH, preventing acid-induced artifacts in tissue and improving nucleic acid preservation for further diagnostic techniques like immunohistochemistry or molecular testing.
