Discover the 4% Formaldehyde Canister (w/v) 10% buffered formalin (v/v) in a 10-liter container, an essential product for all professionals in the histopathology field. This fixative is highly effective for tissue preservation and analysis, ensuring high-quality results.

What is 4% Formaldehyde?

4% formaldehyde, commonly known as 10% formalin, is a non-coagulant primary fixative, widely used in pathology and histology laboratories. Its main function is to
inactivate autolytic enzymes and bacteria, preventing tissue putrefaction and providing structural stability to the chemical components of the protoplasm.

Main Features

• Composition: Formaldehyde (3.80% ÷ 4.40%), Methanol < 0.1%, Disodium phosphate, Monosodium phosphate, Deionized water.


• Buffer molarity: 75 millimoles/liter.


• pH: 7 ± 0.1.


• Fixation ratio: 1:20 (tissue/fixative liquid).

Advantages of 4% Formaldehyde

Using 4% formaldehyde offers numerous advantages:

• Rapid penetration into tissues.


• Gradual hardening, avoiding the formation of a microscopic spongy network.


• Very low oxidation potential, ensuring gentle fixation.


• Ease of use thanks to its chemical stability.

Usage Instructions

The fixation time must be assessed by the operator based on the volume and type of sample. It is essential to respect the 1:20 volume ratio to ensure adequate fixation.
In addition, it is recommended to closely monitor the process to obtain optimal results.

Applications of 4% Formaldehyde

This product is ideal for:

• Fixation of biological samples for histological analysis.


• Preparation of sections for microscopy.


• Preservation of tissues for future studies.

Conclusion

The 4% Formaldehyde Canister (w/v) 10% buffered formalin is an indispensable product for histopathology laboratories. Its effectiveness and versatility make it the perfect choice for every professional in the field.
Make sure you always have this high-quality fixative available to ensure excellent results in your analyses.
