Polymerase chain reaction (PCR) is a technique widely used in molecular diagnostics. DNA is used as a template for replication. PCRs make it is possible to amplify a single copy of DNA and generate several million copies. The primary PCR method uses a thermal cycling technique, which rapidly heats and cools the DNA sample to a defined series of temperature steps.
In modern PCR machines, thermoelectric cooler assemblies can be used to achieve rapid temperature changes. Thermoelectric cooler assemblies offer several advantages over other types of thermal cycling devices including precise temperature control, compact form factor, faster temperature ramp rates and efficiency.
Laird Thermal Systems’ space-saving thermoelectric cooler assemblies suit applications that require high reliability and high volume thermal cycling between multiple temperature set points. If required, we can provide custom designs to fit your specific application needs.
