Shanghai Xinzhuang Instrument Co., Ltd. offers a high-precision cryostat, also known as a high-precision cryostat bath, which is an advanced constant temperature source equipped with its own refrigeration and heating system. This device functions similarly to a small chiller and is widely used in various fields such as petroleum, chemical, metallurgy, pharmaceuticals, biochemistry, physical properties testing, and chemical analysis. It is commonly found in research departments, universities, factory laboratories, and metrology quality inspection units.
The cryostat allows for constant temperature testing within the bath, or it can be connected to external equipment via hoses to serve as a constant temperature source. Two main circulation modes are available: external and internal. External circulation uses a pump to connect the bath to external devices through insulated hoses, creating a closed loop that maintains a stable external temperature field. Internal circulation ensures even temperature distribution within the tank by circulating the liquid medium, minimizing temperature fluctuations.
This type of thermostat is widely applied in multiple areas. In biochemical fields, it supports equipment like rotary evaporators, Abbe refractometers, polarimeters, atomic absorption spectrometers, ICP-MS, ICP, nuclear magnetic resonance systems, CCD cameras, bioreactors, and chemical reactors. In materials science, it is used for electron microscopy, X-ray diffraction, X-ray fluorescence, vacuum sputtering, coating machines, semiconductor devices, and more. In the medical field, it supports superconducting MRI, linear accelerators, CT scanners, and other medical cooling systems. In physicochemical applications, it is essential for lasers, magnetic fields, molecular pumps, and various water-cooled equipment.
The cryostat features energy-saving capabilities, allowing cooling water to be recycled during summer or high ambient temperatures, significantly reducing water consumption. It is highly efficient, capable of meeting the cooling needs of multiple external devices simultaneously, providing a stable constant temperature source for condensation experiments. The device employs PID temperature control technology, integrated PT100 sensors, and digital temperature display, ensuring high accuracy and intuitive operation. Additional safety features include self-diagnosis, overload protection, and anti-freeze solutions.
Low-temperature antifreeze options include ethylene glycol-water mixtures (55/45 for -30°C, 70/30 for -40°C) and glycerol-water mixtures (70/30 for -30°C). Proper density checks are required: for ethylene glycol solutions, P20 should be 1079 kg/m³ at -30°C and 1065 kg/m³ at -40°C; for glycerol solutions, P20 must be 1182.6 kg/m³ at -30°C, with the minimum antifreeze temperature above 0°C.
Cooling water selection depends on the application. Small units (under 1000W) are suitable for lab condensing devices like low-power lasers, parallel evaporators, and distillation meters. Medium units (under 6000W) are ideal for analytical instruments such as AAS, ICP, ICP-MS, and electron microscopes, as well as laser marking and cutting machines. Large units (over 10KW) are used in high-demand equipment like X-ray diffractometers, mass spectrometers, fatigue testing machines, and nuclear magnetic resonance systems.
As the bio-industry develops, the demand for ultrasonic cell disruptors has increased, requiring precise temperature control for samples and overall system performance. These advancements highlight the growing importance of reliable and accurate temperature regulation in scientific research and industrial applications.
