How do you measure elongation of tension specimen?
The elongation of a tension specimen can be measured by marking a gauge length on the specimen before testing it and then comparing the final length of the specimen after it has been stretched to the original gauge length. The elongation can be calculated using the formula: Elongation = ((final length - original length) / original length) x 100%.
Does a fresh specimen go in formalin?
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 must be centered in the field of view on low power before going to high power?
Because when looking at it from far, then you can see more of the specimen, However, when you're looking at it closer up in a high power mode, then you will see less of the object, but much closer.
How do you prevent contaminating a specimen with extraneous micoorganisms?
To prevent contamination of a specimen with extraneous microorganisms, maintain a sterile working environment, use proper aseptic techniques, and handle the specimen carefully to avoid contact with surfaces or airborne contaminants. Additionally, ensure that all equipment used is properly sterilized before use.
Why is it important to center a specimen on low power before attemping to focus on it at high power?
Centering a specimen on low power ensures that it is within the field of view and makes it easier to locate and focus on at high power. If a specimen is not centered on low power, it may be difficult to find and focus on when switching to high power, leading to potential damage to the specimen or microscope lenses. Additionally, centering the specimen helps to achieve the best image quality and clarity at high magnification.
