Introduction

Point of care testing (POCT) aims to bring medical care conveniently and immediately to the patient. The sophistication of medical and laboratory testing devices now enables accurate, real-time diagnostic test results within an hour, rather than days. POCT is addressing the importance for doctors and patients to rapidly receive test results to not only improve patient care, but also improve public health. The recent global COVID-19 pandemic has shown that rapid testing is vital to effectively manage the spread of a virus.

Laird Thermal Systems Increases Reliability of PCR Cycling

PowerCycling PCX Series thermoelectric coolers are assembled with next generation materials and process controls to enhance performance & reliability over standard product offerings…

Thermoelectric coolers boost reliability

PowerCycling PCX Series thermoelectric coolers provide high reliability for demanding thermal cycling applications. Product series is designed to handle hundreds of thousands of thermal cycles, providing improved performance and long-life operation in testing applications. Products offer a robust construction with a flexible thermally conductive ‘soft layer’ to reduce mechanical stresses in thermal cycling applications. Devices extend the mean time between failure (MTBF) of point of care equipment, lowering the total cost of ownership.

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.
