Electron microscopes are used in research laboratories to examine texture, size and composition of biological and inorganic specimens. Unlike traditional light microscopes that use light rays, electron microscopes use an electron beam. The main advantage is the higher image resolution, enabling a magnification of up to 2 million times, whereas light microscopes only have magnification up to 1000-2000 times. As the high voltage electron beam passes through several key components in the electron microscope, active cooling is required to ensure proper operation. Thermal fluctuations can deteriorate image quality and have a negative impact on samples during examination. Designers of electron microscopes face challenges such as precise temperature control, moisture protection, hazardous coolant restrictions and a smaller footprint. Offering a high coefficient of performance (COP) in a compact form factor, modern compressor-based refrigeration systems can meet all of these design challenges.
With a thermal accuracy of ±0.1°C, Laird Thermal Systems' Nextreme™ Chiller platform provides precise temperature control for laboratory instruments like electron microscopes. Utilizing high-performance variable speed motors, the chiller operates at low noise levels with a reduced energy consumption by up to 50% compared to conventional compressor-based systems.
