S212 1–5 L Double-Layer Glass Reactor
Product Overview
The S212 1–5 L Double-Layer Glass Reactor is a jacketed laboratory glass reactor designed for chemical synthesis, reaction, mixing, heating, cooling and vacuum applications. Available in 1 L, 2 L, 3 L and 5 L configurations, it combines a borosilicate glass reaction vessel, variable-speed stirring system, PTFE sealing and a stainless steel support frame.
The reactor uses GG17 borosilicate glass, providing good physical and chemical resistance for laboratory reaction processes. The variable-frequency stirring system provides smooth and reliable operation with high torque and spark-free operation.
Its double-layer jacket allows heating or cooling media to circulate around the reaction vessel. The jacket is designed to allow the heating or cooling liquid to be completely drained after operation, minimizing residual liquid accumulation.
The S212 can also be configured according to specific customer requirements for heating, cooling, reaction vessel and lid components.

Key Features
• High-quality borosilicate glass: The reaction vessel is made of GG17 borosilicate glass with good physical and chemical properties.
• Variable-speed stirring: Stirring speed can be adjusted from 0 to 1200 rpm for flexible reaction control.
• Stable high-torque operation: The variable-frequency drive provides smooth and reliable stirring with high torque.
• PTFE sealing system: Specialized PTFE sealing components provide excellent sealing performance and support vacuum operation.
• High vacuum capability: The sealing system can maintain a vacuum level of approximately -0.095 MPa under suitable operating conditions.
• Wear-debris collection: A dedicated collection groove helps collect sealing material wear debris.
• Stainless steel frame: The complete support frame uses a robust stainless steel structure, including stainless steel three-way and four-way connectors.
• Mobile design: Equipped with locking casters for convenient movement and positioning.
• Low-dead-volume discharge valve: The PTFE discharge valve is designed to minimize or eliminate dead zones and facilitate material discharge.
• Efficient jacket drainage: Heating or cooling liquid in the reaction jacket can be thoroughly drained after operation to minimize liquid accumulation.
• Heating and cooling options: Compatible heating or cooling configurations can be supplied according to application requirements.
• Customizable configuration: The reaction vessel and lid can be customized according to customer requirements.
• Compact structure: The overall design combines structural strength, practicality and convenient laboratory operation.

Working Principle
The S212 Double-Layer Glass Reactor uses a jacketed reaction vessel to provide controlled thermal conditions for laboratory reactions.
The reaction materials are placed inside the borosilicate glass vessel. A heating or cooling medium is circulated through the outer jacket surrounding the reaction vessel, transferring heat to or from the reaction mixture. This allows the reaction temperature to be controlled without directly contacting the sample with the heating or cooling medium.
The integrated stirring system uses a variable-frequency motor to rotate the stirring shaft. The stirring speed can be continuously adjusted within the specified range, promoting uniform mixing and improving heat and mass transfer throughout the reaction mixture.
The PTFE sealing assembly minimizes air leakage between the rotating shaft and reactor vessel, allowing the system to operate under vacuum conditions. The vacuum environment can be used for processes such as low-temperature solvent evaporation, concentration and reactions requiring reduced pressure.
