Used in laboratory environments, analytical instrumentation equipment is designed to increase functionality while reducing size to free up precious lab space. Packing more electronics into a tighter footprint increases the heat flux, which leads to thermal challenges. Waste heat must be efficiently managed to meet conflicting requirements of increased performance with reduced power consumption and quieter operation all in a compact design. For systems that require refrigeration for specific reaction temperatures, such as benchtop incubators, laboratory centrifuges, chromatography and clinical chemistry analyzers, temperature control systems play an important role in performance, size and improving test results. Thermoelectric Assemblies (TEAs) offer cooling solutions that enable OEMs to meet thermal challenges with advanced temperature, humidity and moisture control.
Centrifuges are used in medical and analytical laboratories to separate fluids through centrifugal force. A centrifuge spins samples at a very high speed pushing dense substances away from the center axis while less dense particles are drawn towards the axis. Due to the heat generated by the spinning centrifuge itself and the importance of maintaining a steady temperature for samples, a thermal management solution is required.

Incubators are used in hospitals and laboratories to grow and maintain cell cultures. To create the best conditions for cell growth, incubators are designed to maintain a constant temperature and humidity. Deviations above and below the body temperature of 37°C have a negative effect on cell health. Peltier thermoelectric assemblies provide a more efficient, reliable, lower maintenance and lower cost-of-ownership solution for incubator temperature control.

Liquid chromatography is a technique used for analysis of mixtures by separating, identifying, and quantifying their constituent components. Temperature control plays a major role in the liquid chromatography separation process by influencing the interactions taking place between the sample components and adsorbent. Laird Thermal Systems’ complete thermal management systems optimize liquid chromatography equipment by offering precise temperature control, compactness, faster temperature ramp rates and greater efficiency.
