Methods: RDs were sterilized by either an autoclave, gamma irradiation, or chemical … In heat sterilization process, the longer the exposure to heat the better is the sterilization at a given temperature. Sterilization– it is defined as the process by which an article, surface or medium is freed of all living microorganism either in the vegetative or spore state. For medical grade silicones, heat sterilization is preferred in the form of steam autoclaving. Wipe the outside of the autoclave with a damp cloth and a mild detergent. At constant temperatures, sterilization times vary depending on the type of item (e.g., metal versus rubber, plastic, items with lumens), whether the item is wrapped or unwrapped, and the sterilizer type. Autoclaves can be used to eliminate microorganisms, cure composites, vulcanize rubber, and for hydrothermal synthesis.

Found inside – Page 543The are several methods of sterilization for parenteral products, ... of choice for sterilization of aqueous solutions, glassware, and rubber articles. Heat. The process of industrial autoclaves includes bonding of structural adhesives, vulcanization of rubber, and processing of composite parts. 121 C, Steam pressure 15 PSI and holding time 15 minutes. 4. Now in its thoroughly revised, updated Fifth Edition, this volume is a comprehensive, practical reference on contemporary methods of disinfection, sterilization, and preservation and their medical, surgical, and public health applications. Disinfection: Disinfection is a method of freeing an article or instrument from some or all living pathogens which may produce the infection during the use of the instruments contaminated with the pathogens. (autoclaves), the decontamination of cultures and other materials, the preparation of sterile supplies and the safe operation of autoclaves. Additional rubber outer sole and heel suede panel. An autoclave is a pressure chamber used to carry out industrial processes that require elevated temperature and pressure, which is different from the ambient air pressure. c)Sterilization by radiation: Eg: Use of Ultra-violet rays: UV light(Non-ionising), Ionising radiations: X-rays, Gamma rays, beta rays. The absence of moisture is of utmost importance for the longevity of the pliers (Rapisarda et al., 1999). Treatment of inert surfaces and heat labile materials can be accomplished through the Ethylene oxide is widely used in this method for medical and pharmaceutical fields. However, it uses very hi gh temperature which i s harsh or not. Please use one of the following formats to cite this article in your essay, paper or report: APA. It is generally accepted that terminally sterilized injectable articles or critical devices purporting to be sterile, when processed in the autoclave, attain a 10 –6 microbial survivor probability, i.e., assurance of less than 1 chance in 1 million that viable microorganisms are present in the sterilized article or dosage form. The most common method of testing is using commercially available test indicator kits with spore strips (usually Bacillus stearothermophilus).
