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. Plage de température

• 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. Capacité de refroidissement

• 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. Pompe de circulation

• 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. Système de contrôle de la température

• 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. Mesures de protection de la sécurité

• Protection contre la surchauffe : Coupe automatiquement l'alimentation électrique lorsque la température dépasse la valeur fixée.
• Protection contre la surpression : Empêche la pression du système d'être trop élevée.
• Détection des fuites : Détecter si le système présente des fuites.
• Bouton d'arrêt d'urgence : permet d'arrêter rapidement le fonctionnement du système en cas d'urgence.

6. User interface

• Écran tactile ou numérique : Affichage intuitif de la température actuelle, de la température de consigne et d'autres paramètres.
• Interface d'utilisation conviviale : Facilité de réglage et de contrôle de la température, prise en charge des fonctions de programmation et d'enregistrement des données.

1. Type de refroidisseur

• 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. Capacité de refroidissement

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

3. Pompe de circulation

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

4. Système de contrôle de la température

• Contrôleur PID : permet de contrôler la température avec une grande précision.
• Temperature sensor: installed at key positions of the reactor and the cooling water machine to monitor the temperature in real time.

5. Dispositif de protection de sécurité

• Protection contre la surchauffe : coupe automatiquement l'alimentation électrique lorsque la température dépasse la valeur fixée.
• Protection contre la surpression : empêche la pression du système d'être trop élevée.
• Détection des fuites : détecter si le système présente des fuites.
• Bouton d'arrêt d'urgence : permet d'arrêter rapidement le fonctionnement du système en cas d'urgence.

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.
