Formalin is the most widely used fixative in histology and anatomical pathology, essential for preserving tissue morphology and cellular detail in specimens destined for microscopic examination. Selecting the right formalin product for your workflow — whether ready-to-use or concentrate — ensures consistent fixation quality and efficient laboratory operations.
At Hurst Scientific, we supply formalin fixative to pathology laboratories, hospitals, mortuaries, veterinary practices, and research institutions across Australia.
10% Neutral Buffered Formalin (NBF) is the standard fixative for routine histology and surgical pathology. The phosphate buffer maintains a neutral pH, which is critical for preserving antigenicity and ensuring reliable results in downstream staining procedures including immunohistochemistry. Ready to use straight from the container.
Formalin Concentrate (5x) is a concentrated formalin solution that laboratories dilute on-site to prepare working strength fixative. Reduces freight volume and storage space requirements — particularly useful for high-volume laboratories.
Formalin Concentrate (8x) provides an even higher concentration for laboratories requiring maximum flexibility in preparation of working solutions or specialist fixative formulations.
Formalin is classified as a hazardous substance and should be handled in accordance with Australian workplace health and safety regulations. Always use formalin in well-ventilated areas or under local exhaust ventilation. Appropriate PPE including chemical-resistant gloves, eye protection, and a laboratory coat should be worn at all times when handling formalin.
Safety Data Sheets (SDS) for all Hurst Scientific formalin products are available on our SDS page.
What is the correct fixative to tissue ratio for formalin fixation? A minimum ratio of 10 parts formalin to 1 part tissue by volume is recommended to ensure adequate and uniform fixation. Insufficient fixative volume is one of the most common causes of poor fixation quality.
