The flow created by the blower ensures uniform temperatures and the equal transfer of heat throughout the load. For this reason, the mechanical convection oven is the more efficient of the two processes.
Hot air oven: used in sterilizing instruments for various aseptic procedures, specially if that can not be autoclaved like powders Koch's or Arnold's steam sterilizer: used for steam sterilization A pressure cooker: used as a portable autoclave Biological and chemical indicators
Other forms of the laboratory oven include vacuum ovens, forced air convection ovens, and gravity convection ovens. [1] Forensic labs use vacuum ovens that have been configured in specific ways to assist in developing fingerprints. Gravity convection ovens are used for biological purposes such as removing biological contaminants from samples ...
