To a 10th of a degree with pinpoint accuracy: Infrared LED-heated measuring chamber for moving, fluid samples by Solectrix
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 previously common heating elements like Peltier elements or heating cartridges. Thus, the desired temperature within the chamber can be reached much faster. All the electronics and sensors are located underneath the sample carrier and do 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 comments: “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 the measurement data.”
