Microwave oven in microbiology.
Editor, Reference to Microwave oven in microbiology laboratory, JPMA., 1992:42:2. In response to the queries by a microbiologist regarding the published paper we feel it would be appropriate to clarifr the facts. 1. Sterilization in microwaves works on a different principle than the conventional autoclave and sterilizadon is independent of temperature, just like the principle of sterilization b...
متن کاملMicrowave oven in microbiology laboratory.
Microwave oven can safely be used in microbiology laboratory for preparation of media. The method is convenient, reliable, economical and reproducible. It saves time and the quality of media is superior as compared to media prepared by conventional autoclaving method.
متن کاملA review of microwave oven safety.
The microwave leakage from current microwave ovens, which are manufactured to meet government emission standards, is reviewed. Typical leakage values imply exposure values well below the most conservative exposure standards in the world. A review of recent developments discloses increasingly stringent government regulation along with advances in techniques for suppression of microwave leakage. ...
متن کاملAccelerated Drying of Plaster Casts with a Microwave Oven
Calcined gypsum (calcium sul phate hemihydrate, CaS04 1/2H20), commonly known as plas ter of Paris, is used extensively in forming casts to immobilize parts of the body and for making molds used in the manufacture of orthotic and prosthetic devices. Plaster models and casts have several advantages, and a few disadvantages. Widely available, plaster is inert, sufficiently stable dimensionally,...
متن کاملPhysics of the microwave oven
This is the first of two articles about the physics of microwave ovens. This article deals with the generation of microwaves in the oven and includes the operation of the magnetrons, waveguides and standing waves in resonant cavities. It then considers the absorption of microwaves by foods, discussing the dielectric relaxation of water, penetration depths of electromagnetic waves in matter and,...
