Product Overview

10% Neutral Buffered Formalin (NBF), pH 7 is the gold standard fixative used worldwide in histology, pathology, and anatomical specimen preparation. This ready-to-use solution contains approximately 4% formaldehyde in a phosphate-buffered aqueous base, maintaining a stable pH of 7.0. Buffering prevents the formation of formalin pigment (acid hematin) and helps preserve tissue morphology during fixation and long-term storage.

NBF is widely compatible with downstream staining protocols, including Hematoxylin & Eosin (H&E), special stains, and immunohistochemistry (IHC). It provides excellent nuclear and cytoplasmic detail, making it suitable for a wide range of tissue types and clinical applications. Its balanced formulation minimizes tissue shrinkage and maintains reproducibility in diagnostic and research workflows.

Key Features:

• Contains ~4% formaldehyde (10% formalin) buffered to pH 7.0
• Buffered with phosphate salts to maintain neutral pH stability
• Prevents acid formalin pigment formation and tissue artifact
• Ideal for biopsy fixation, surgical specimens, and research tissues
• Compatible with H&E, IHC, molecular testing, and special stains
• Provides consistent, high-quality morphological preservation

10% Neutral Buffered Formalin (pH 7) is the industry-preferred fixative for routine tissue processing, ensuring accurate diagnostics, excellent staining quality, and long-term tissue integrity in both clinical and laboratory settings.
