When choosing the right circulating chiller for your 100 mL laboratory reactor, there are several factors to consider to ensure that the equipment can provide precise temperature control and efficient cooling.

1. Temperature Range

• Temperature Range: Choose the right temperature range based on your experimental needs. Typically, laboratory reactors may require a temperature range between -20°C and 100°C.
• Control Accuracy: Choose a system with high-precision temperature control, typically with a control accuracy of ±0.1°C or less.

2. Cooling capacity

• Cooling capacity: Select the appropriate cooling capacity based on the heat load of the reactor and the required cooling rate. For a 100 ml reactor, a smaller cooling capacity is usually required, generally between 1-2 kW.
• Heating capacity: If experiments need to be performed under different temperature conditions, select a chiller with heating function.

3. Circulating pump

• Flow rate: Select the appropriate circulating pump flow rate to ensure that the cooling water flows evenly between the reactor and the chiller. For a 100 ml reactor, the flow rate is usually between 1-5 L/min.
• Lift: Select the appropriate lift according to the resistance of the system, usually between 1-5 meters of water column.

4. Temperature control system

• PID controller: Achieve high-precision temperature control and adjust the heating and cooling power through the feedback control system.
• Temperature sensor: Installed at key positions of the reactor and the chiller to monitor the temperature in real time.

5. Safety protection measures

• Overtemperature protection: Automatically cut off the power supply when the temperature exceeds the set value.
• Overpressure 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.

6. User 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.

1. Chiller type

• Water-cooled chiller: Suitable for occasions requiring high-precision temperature control and high cooling efficiency.
• Air-cooled chiller: Suitable for occasions with limited space or insufficient water supply.

2. Cooling capacity

• Cooling capacity: 1-2 kW
• Heating capacity: If necessary, choose a cooling water machine with heating function.

3. Circulation pump

• Flow rate: 1-5 L/min
• Head: 1-5 meters of water column

4. Temperature control system

• PID controller: achieve high-precision temperature control.
• Temperature sensor: installed at key positions of the reactor and the cooling water machine to monitor the temperature in real time.

5. Safety protection device

• Overtemperature protection: automatically cut off the power supply when the temperature exceeds the set value.
• Overpressure 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.

1. Chemical synthesis:

• In the process of chemical reactions such as organic synthesis and inorganic synthesis, precise temperature control is required to improve the yield and purity.
• For example, some organic reactions need to be carried out under low temperature conditions to prevent the occurrence of side reactions.

2. Materials Science:

• In the process of preparing nanomaterials, crystal growth, etc., it is necessary to accurately control the temperature to obtain the desired material properties.
• For example, the synthesis of some nanomaterials needs to be carried out at a specific temperature to ensure the uniformity of size and morphology.

3. Biotechnology:

• In biological experiments, the temperature needs to be accurately controlled to ensure the smooth progress of processes such as cell culture and enzyme catalysis.
• For example, some cell cultures need to be carried out at a constant temperature to ensure cell growth and metabolism.

In summary, when choosing a suitable circulating chiller for a 100 ml reactor in the laboratory, factors such as temperature range, refrigeration capacity, circulating pump flow, temperature control accuracy, and safety protection measures should be considered comprehensively. By choosing the right equipment, it can be ensured that the experiment is carried out under precise temperature conditions, and the accuracy and repeatability of the experimental results can be improved.
