Intelligent temperature regulation without an expensive Peltier element, plus energy-free measuring with data readout via RF - these are the strengths of the new measurement chamber for moving, fluid samples developed by Solectrix GmbH from Nürnberg.
The temperature is regulated via individually controlled infra-red LEDs, which enables a far more constant temperature level in the disc than with conventional heating systems. The result is an temperature accuracy of ±0.35 °C at 7500 rpm.
The radially arranged LEDs replace the heating cartridge previously used in such applications, thus enormously accelerating the heating and switch-off reaction of the chamber, enabling shifts within seconds. The PCB with the measurement electronics is attached directly underneath the disc with the fluid and does not require an individual power source. One application field for the measurement chamber is the temperature regulation and analysis of blood serum. Says Jürgen Steinert, CEO and project lead at Solectrix: "Our LED heating system is a very elegantl and cost-effective way for all use cases where a moving fluid needs to be temperature-regulated while reading out data."
