Microbiology of food and animal feeding stuffs. Polymerase chain reaction (PCR) for the detection of food-borne pathogens. Performance testing of thermal cyclers Ingestion-build-146508 BS 5499-4 gives further recommendations1 Scope This Technical Specification provides basic requirements for the installation, performance and maintenance of thermal cyclers. Although thermal cyclers are robust technical equipment, they do require regular maintenance. Their cooling heating elements, either Peltier or other technology, have a limited lifetime. Proper functioning of the cooling heating element depends both on the quality of the cooling heating devices and proper use and care.
