5 Consult other instrument temperature control units

X-ray diffraction (XRD) systems are widely used in materials science, chemistry, physics and other fields to study the crystal structure of substances. In order to conduct experiments under different temperature conditions, a heating and cooling circulator that can provide precise temperature control is usually required. This equipment can ensure that the sample remains stable within the required temperature range, so as to obtain accurate diffraction data.

Main features

Wide temperature range:

Temperature range: -25°C to 200°C
Such a temperature range can cover a variety of experimental needs from low temperature to high temperature.

High-precision temperature control:

The control accuracy is usually ±0.1°C or less to ensure high consistency of experimental conditions.
Use PID controller or other advanced temperature control technology to achieve fast and stable temperature adjustment.

Fast heating and cooling capabilities:

Fast heating: Able to heat the sample to the set temperature in a short time.
Fast cooling: Through an efficient refrigeration system, the sample is quickly cooled to the required temperature.
Helps improve experimental efficiency, especially when temperature conditions need to be changed frequently.

Circulation pump:

The built-in circulation pump circulates the cooling medium (usually thermal oil or water/ethylene glycol solution) between the heating/cooling unit and the sample chamber to ensure uniform temperature distribution.
The flow rate of the circulation pump should match the sample chamber of the XRD system, usually between a few liters per minute and tens of liters per minute.

Safety protection measures:
•Over-temperature protection: Automatically cut off the power supply when the temperature exceeds the set value.
•Over-pressure protection: Prevent the system pressure from being too high.
•Leak detection: Detect whether the system has leaks.
•Emergency stop button: Quickly stop the system operation in an emergency.

Operation interface:
•Touch screen or digital display: Intuitively display the current temperature, set temperature and other parameters.
•User-friendly operation interface: Easy to set and monitor temperature, support programming and data logging functions.

Compatibility:
•Compatible with the sample chamber interface of the XRD system to ensure seamless integration.
•Specific connectors or adapters may be required to connect the circulator and the sample chamber.

Application field

Material science:
•Study the changes of crystal structure of materials at different temperatures, such as phase change, thermal expansion, etc.
•Evaluate the performance of new materials under high or low temperature conditions.

Chemistry:
•Study the crystal structure of compounds at different temperatures to understand their thermal stability.
•Explore the changes of crystal structure during reaction.

Chemistry:
•Study the crystal structure of compounds at different temperatures to understand their thermal stability.
•Explore the changes of crystal structure during reaction.

Physics:
•Study the change of solid physical properties with temperature, such as magnetism, conductivity, etc.
•Explore the behavior of new materials under extreme temperature conditions.

Geology:
•Study the crystal structure of minerals at different temperatures and understand the physical processes inside the earth. Summary Heating and cooling circulators for X-ray diffraction systems are important auxiliary equipment that can provide a wide temperature range (-25°C to 200°C), high-precision temperature control, and fast heating and cooling capabilities. This equipment is essential for accurate XRD analysis under different temperature conditions.

When choosing a heating and cooling circulator, the following factors should be considered:

Temperature range: Make sure the system can cover the required temperature range.
Temperature control accuracy: Choose a system with high-precision temperature control, such as a PID controller.
Heating and cooling capacity: Choose heating and cooling power that suits the experimental needs.
Safety: Make sure the system has multiple safety protection measures to ensure the safety of operators and equipment.
Compatibility: Make sure the circulator is compatible with the sample chamber interface of the XRD system.

It is recommended to consult a professional equipment supplier or engineer before purchasing to ensure that you choose the heating and cooling circulator that best suits your needs.
