Point of care testing enables medical staff to deliver real-time test results within an hour. To ensure accuracy and long operational life of test devices, thermoelectric coolers are used to provide precise temperature control. Point-of-care PCR testing devices must handle hundreds of thousands of thermal cycles throughout its life with minimal degradation to the thermoelectric cooler. Our PowerCycling PCX Series thermoelectric cooler features a unique construction that is tested to survive in long term thermal cycling applications. 


Online Thermoelectric Modelling Tool for PCR Design Engineers


Laird Thermal Systems has launched an online simulation tool for PCR thermal cycling applications. Thermoelectric coolers produced for thermal cycling, such as the PowerCycling PCX Series, are utilised for Real-Time PCR to precisely temperature control DNA amplification to three temperature set points. Constructed with next-generation thermoelectric material, the series offers faster ramp rates and higher reliability than conventional thermoelectric coolers to notably extend field use of molecular diagnostic devices.





Cooling Solutions for Autonomous Systems


Advances in autonomous technologies, such as smart headlights, autonomous systems for collision avoidance, and infotainment systems, require enhanced thermal protection of critical electronics to ensure optimized performance. These emerging intelligent autonomous systems are increasingly complex while decreasing in size and weight. Packing more functionality into smaller footprints has increased the heat flux density and thermal challenges in autonomous systems.





New High-Temperature Thermoelectric Coolers from Laird Thermal Systems Cool Optical Sensors in Advanced Driver-Assistance Systems (ADAS)


Advanced driver-assistance systems (ADAS) use a variety of imaging sensors, cameras and lasers to enhance vehicle safety and create better driving conditions. Most of these optical devices, including CMOS sensors and laser diodes, are heat sensitive and rely on high-resolution images for proper operation. Image quality can quickly deteriorate as the device temperatures rise above 60°C.





UTX Series Thermoelectric Cooler


The new UltraTEC UTX Series is a high-performance thermoelectric cooler that is assembled with advanced thermoelectric materials and can boost cooling capacity by up to 10%. The UltraTEC UTX Series features a higher thermal insulating barrier when compared to standard materials creating a maximum temperature differential (ΔT) of 72°C. It features a high heat pump density, precise temperature control, reliable solid-state operation, and does not create any noise or vibration.





PowerCycling PCX thermoelectric coolers for PCR tests


Point-of-care testing allows medical staff to accurately achieve real-time diagnostic results within an hour, rather than days. PCR-based point of care testing is considered the gold standard for diagnosing COVID-19 because it provides the fastest and most accurate test results. Portable point of care testing (POCT) equipment requires a sophisticated thermal management solution that can withstand mechanical stresses induced by rapid temperature changes.
