VWR Formalin 10%, Q Path®, Buffered is a colourless, neutral buffered formaldehyde solution optimized for tissue fixation in histology and pathology applications. Prepared to 10% formalin (equivalent to ~4% formaldehyde), it is pH-stabilized to 6.8–7.2 for consistent tissue preservation and morphological detail retention.
This high-quality fixative is QC-tested to ensure compliance with formaldehyde concentration, pH, and density specifications, providing reproducible results for clinical, veterinary, and research laboratories.
Key Features
- Buffered for Stability – Maintains pH between 6.8–7.2 for optimal fixation.
- Quality Controlled – Passes formaldehyde test with density at 1.012–1.014 g/cm³ (20/4°C).
- Clear, Colourless Liquid – Ensures clean sample embedding and staining.
- Multiple Pack Sizes – Available from small-volume pots to bulk containers for varied workflows.
Applications
- Histology & Pathology – Routine tissue fixation for paraffin embedding and sectioning.
- Veterinary Diagnostics – Preservation of biopsy and necropsy specimens.
- Research – Morphological preservation for immunohistochemistry (IHC) and molecular techniques.
- Archival Storage – Long-term storage of fixed biological samples.
