Microwave Oven for Sterilization of Medical Equipment

Microwaves could be used in medicine for disinfection of soft contact lenses, dental instruments and dentures. However, microwaves must be used with products that are compatible.

Microwaves are radio-frequency waves, which are usually operated at a frequency of 2450 MHz.

Microwaves produce friction of water molecules in an alternating electrical field.

The intermolecular friction derived from the vibrations generates heat, and some people believe that the effect of microwaves depends on the heat produced, while others postulate a nonthermal lethal effect.

There are some reports showed microwaves to be an effective microbicide.

The microwaves are produced by a microwave oven completely inactivate bacterial cultures, mycobacteria, viruses, and G. stearothermophilus spores within 60 seconds to 5 minutes.
