Solution
The two main purposes of heat fixing are:
-
To kill the bacteria: Heat fixing involves subjecting the bacterial sample to high temperatures, typically around 60-80 degrees Celsius. This heat kills the bacteria, preventing them from further growth or causing contamination during the staining process.
-
To 'stick' the bacteria to the slide: Heat fixing helps in adhering the bacteria to the slide surface. By applying heat, the bacterial cells undergo coagulation, which causes them to stick firmly to the slide. This ensures that the bacteria remain in place during subsequent staining and washing steps.
Overall, heat fixing serves the dual purpose of killing the bacteria and securing their attachment to the slide for further microscopic examination.
