What is ZN Fixative? ZN Fixative (also known as Ziehl-Neelsen Fixative) is a solution primarily used in laboratory settings for the preservation of tissue samples, particularly in the preparation of samples for acid-fast bacillus (AFB) staining, such as in the diagnosis of tuberculosis. The solution typically contains a mixture of methanol, formaldehyde, and other components to stabilise the tissue samples and prevent degradation.

It is crucial in microbiological and histological applications, particularly in ensuring that specimens are properly preserved for subsequent staining and analysis. It plays a key role in enhancing the visibility of certain bacteria, such as Mycobacterium tuberculosis, during the Ziehl-Neelsen staining procedure.

High-Quality Formulation: We carefully manufacture ZN Fixative, ensuring consistent performance across various applications.

Manufactured in the UK: Our ZN Fixative is manufactured and bottled using non-toxic, chemical resistant bottles, providing reliable and trusted quality to our customers.

Frequent uses

Histological and Microbiological Analysis
Commonly used in histology and microbiology for the preservation of tissue samples. It is especially useful for specimens that will undergo acid-fast staining techniques to identify Mycobacterium species and other bacteria that resist standard staining procedures.

Acid-Fast Bacillus (AFB) Staining
The fixative is primarily employed in the Ziehl-Neelsen staining method, a critical technique in identifying Mycobacterium tuberculosis and other acid-fast organisms in clinical and research laboratories. It ensures that the bacterial cell walls are preserved for proper visualization under a microscope.

Diagnostic Testing
Used in diagnostic settings, particularly in tuberculosis testing, where the preservation of sputum or tissue samples is essential for accurate testing and results. It helps maintain sample integrity during transport and preparation for laboratory examination.

Tissue Preservation for Research
Used to preserve tissue specimens that may be further analysed for various microbiological and histopathological studies. It helps maintain cellular structure and prevents enzymatic degradation during sample handling.
