Yes, a fresh specimen can be placed in formalin for fixation and preservation before processing for histological analysis. The formalin helps prevent degradation of tissue structures and maintain their integrity.
The specimen should be placed in formalin solution after harvesting to preserve the tissue for estrogen and progesterone receptor studies. Formalin fixation helps to maintain the structure and integrity of the tissue for subsequent analysis.
Formalin is a solution of formaldehyde in water, typically containing about 37% formaldehyde gas by weight. It often includes methanol, which acts as a stabilizer to prevent polymerization of formaldehyde. Additionally, it may contain other additives to enhance its efficacy as a preservative or disinfectant. Overall, formalin is widely used in laboratories and medical settings for tissue preservation and specimen storage.
The container that holds tissue specimens is commonly referred to as a "specimen jar" or "tissue specimen container." These containers are typically made of glass or plastic and are designed to preserve the integrity of the specimen, often containing a fixative solution like formalin to prevent degradation. They are used in laboratories for histological examination and analysis.
To dilute formalin, you can mix it with water in the desired ratio. For example, to create a 10% formalin solution, mix 1 part formalin with 9 parts water. Always handle formalin carefully as it is a hazardous chemical and follow proper safety protocols.
abbreviation for Neutral Buffered Formalin
Formalin is used in the clinical and pathology labs to preserve the ova and parasites that might be found in a stool specimen, gastric specimen. Pathology uses formalin to preserve tissue that is removed for exam and special staining.

yes
the best answer of advantage of fresh specin to identify the color and to see what happened the materiel inside specimen...

Noting the color of a specimen before drying or soaking in formalin is essential for accurate documentation and diagnosis. The original color can provide valuable information about the specimen's condition, pathology, and potential changes that may occur during preservation. Changes in color during processing could indicate chemical reactions or degradation, which may affect the interpretation of the specimen in future analyses. Proper color documentation ensures that any alterations are understood and assessed in context.

The objective used when observing a fresh specimen is typically a low-power objective lens, such as a 4x or 10x lens. This allows for a wider field of view and better visualization of the overall sample without the need for magnification.
I have never heard it used that way
