Shanghai Xinzhuang Instrument Co., Ltd. offers a high-precision cryostat, also known as a high-precision cryostat bath. This device is a self-contained constant temperature source that integrates both refrigeration and heating functions, effectively serving as a compact chiller. It is widely utilized in various fields such as petroleum, chemical engineering, metallurgy, pharmaceuticals, biochemistry, physical properties testing, and chemical analysis. The equipment is commonly found in research departments, universities, factory laboratories, and metrology inspection units.
The cryostat allows for constant temperature testing directly within the bath or can be connected to external devices via hoses to serve as an external constant temperature source. It features both internal and external circulation modes. Internal circulation ensures uniform temperature distribution within the tank by circulating the liquid medium, while external circulation connects to other equipment through insulated hoses, creating a closed-loop system that maintains a stable external temperature field.
This equipment is extensively used in multiple application areas. In the biochemical field, it supports devices like rotary evaporators, Abbe refractometers, polarimeters, atomic absorption spectrometers, ICP-MS, ICP, NMR, CCD cameras, biological fermenters, and chemical reactors. In materials science, it is used with electron microscopes, X-ray diffraction systems, X-ray fluorescence spectrometers, vacuum sputtering machines, semiconductor devices, and more. In the medical field, it supports superconducting MRI machines, linear accelerators, CT scanners, and other imaging and therapeutic devices. In physical and chemical research, it powers lasers, magnetic fields, molecular pumps, and various cooling systems.
The cryostat includes energy-saving features, allowing for the reuse of cooling water during summer or high ambient temperatures, significantly reducing water consumption. It provides efficient cooling for multiple external devices simultaneously, making it ideal for condensation experiments. With advanced PID temperature control technology, built-in PT100 sensors, and digital temperature display, it ensures high precision and intuitive operation. Additional safety features include self-diagnosis, overload protection, and anti-freeze solutions.
For low-temperature applications, ethylene glycol-based antifreeze solutions are available: 55/45 (–30°C) and 70/30 (–40°C). Glycerol-based solutions at 70/30 (–30°C) are also offered. It's important to check the density of these solutions to meet specific requirements. For example, ethylene glycol solutions should have a density of 1079 kg/m³ at –30°C, and glycerol solutions must maintain a minimum temperature above 0°C.
Cooling water selection depends on the system’s capacity. Small units (under 1000W) are suitable for lab instruments like low-power lasers, parallel evaporators, and distillation meters. Medium-sized units (under 6000W) are ideal for analytical instruments such as AAS, ICP, 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, and nuclear magnetic resonance systems.
In the development of the biotechnology industry, the need for precise temperature control in applications like ultrasonic cell disruptors has increased, including better sample temperature management and overall system performance. These advancements highlight the growing importance of reliable and accurate cryostats in modern scientific research.
