Online thermoelectric modeling tool for PCR designers


05-11-2021 | Squire | Design & manufacture

Laird Thermal Systems has launched an online simulation tool for PCR thermocycling applications. Thermoelectric coolers that are made for thermal cycling, such as the PowerCycling PCX series, are used for real-time PCR to precisely temper the DNA amplification to three temperature setpoints. Made from next-generation thermoelectric material, the series offers faster slew rates and greater reliability than traditional thermoelectric coolers to significantly expand the field of molecular diagnostic equipment.

Choosing the best thermoelectric cooler for thermal cycling can be a difficult process for any designer. To assist with product selection, the company has developed an advanced application tool for the Thermal Wizard for PCR. This is a web-based simulation tool that allows designers to enter familiar attributes such as geometry constraints, desired setpoint temperatures, and thermal mass on the control side to estimate the heat pump capacity required to provide specific ramp rates.

“Choosing thermoelectric coolers can be quite difficult. The Thermal Wizard allows customers to calculate approximate heat load requirements and then simulate performance based on the operating conditions specified by the user, ”said Andrew Dereka, Product Director at Laird Thermal Systems. “The Thermal Wizard recommends a particular PCX thermoelectric cooler or range of coolers that are capable of meeting the user-specified input application attributes.”
