Correct answer: B. Hot air oven
- A. Autoclaving
- B. Hot air oven
- C. UV-Radiation
- D. Inspissation
Explanation
Liquid paraffin is sterilized by dry heat in a hot-air oven because it is non-aqueous and would not be reliably sterilized by steam autoclaving. Inspissation is used mainly for serum- or egg-containing media.
