Intelligent temperature control without an expensive Peltier element and contactless measuring with data readout via RF – these are the strengths of the LED-heated measuring chamber for moving, fluid samples developed by Solectrix.
Regulation of the fluid’s temperature is realized via individually controlled infrared LEDs, which enables a far more consistent temperature level within the sample than with conventional heating systems. The result is a temperature accuracy of ±0.35 °C at 7500 rpm.
The LEDs, arranged radially in the direction of movement, replace the previously frequently used heating elements like Peltier elements or heating cartridges. Thus, the control of the temperature within the chamber can be accelerated enormously. All the electronics and sensors are located underneath the sample carrier and does not require an independent power supply. One of many possible applications for the measuring chamber is the temperature control and analysis of blood serum.
Solectrix managing director and project lead Jürgen Steinert: “Our LED heating system is a very elegant and affordable solution for all applications that require temperature control of a moving sample carrier and readout of measurement data.”
