For the processing process to be as effective as possible, it is necessary to choose the right sterilization method. heating too fast can lead to "hot spots" and "thermal runaway", and the sample temperature is difficult to measure accurately. cannot withstand the c.) very high temperatures it requires to be effective. 3. | Benefits & Side Effects. Subsequently, the test strips and control strips are cultured by placing the strips in a tube of tryptic-digest, casein-soy broth. For sterilization, chemicals such as hydrogen peroxide and bleach are commonly used. Hence it has become mandatory to sanitize these household items. Additionally, when it is applied below the dose that is recommended, it may not be able to get rid of viruses as well. Potential health hazard; fumes must be monitored.
