What Is the Purpose of Heat Fixation? – Reference.com

After a slide has been prepared, it is exposed to intense heat. Usually this is done with some type of flame. This process kills the organism on the slide, and ensures it stays in place on the slide. For some types of organisms, the heat fixation even modifies the organisms or cells in such a way that they become more susceptible to being dyed.

To Heat or Methanol Fix? That is the Burning Question.

The methanol fixation was superior in causing the specimen to adhere securely to the slide. In addition, they found that Gram-positive bacteria were far less likely to become over-decolorized with methanol rather than heat fixation. This confirmed the findings of Mangels, et al in 1984.
