Double-Layer Glass Reactor: User Guide And Key Features

I. Double-Layer Glass Reactor User Guide

The double-layer glass reactor features a vertical, double-layered structure, with both layers constructed from high-borosilicate glass. Reactants are placed inside the inner vessel for stirring and reaction purposes, while the circulation of various heat-exchange media through the outer jacket allows for the heating or cooling of the materials within the vessel. Under controlled constant-temperature conditions—and within the sealed environment of the glass reactor—stirred reactions can be conducted under either atmospheric or negative pressure, depending on operational requirements; furthermore, the system facilitates the reflux and distillation of reaction solutions. Upon completion of the reaction, the processed materials can be discharged via the outlet valve located at the bottom of the vessel, ensuring extremely convenient operation. The double-layer glass reactor is a standard piece of biochemical instrumentation, widely adopted across modern industries such as fine chemicals, biopharmaceuticals, and scientific research laboratories. It enables concentration, distillation, fractionation, separation, and purification processes under conditions of constant speed, constant force, and constant temperature, making it an ideal piece of equipment for educational instruction, laboratory experimentation, pilot-scale testing, and industrial production.

Depending on specific process requirements, different heat-exchange media can be circulated through the reactor's jacket: High-temperature thermal oil (reaching up to 300°C) can be circulated to heat the materials within the vessel and drive the reaction; alternatively, low-temperature refrigerants (reaching down to -80°C) can be circulated to dissipate the heat generated by exothermic reactions, thereby maintaining the desired reaction state. The glass reactor is designed to operate under either atmospheric or negative pressure conditions; the allowable pressure range within the inner vessel is -0.1 to 0 MPa. The allowable working pressure range within the reactor jacket is ≤ 0.03 MPa. The reactor is equipped with a "dead-angle-free" PTFE (Teflon) bottom discharge valve, which not only ensures that there are no dead zones within the reaction vessel but also guarantees a tight, leak-proof seal, thereby enabling complete discharge of materials with absolutely no residue. The nominal volumes available for the double-walled glass reactor include five standard specifications: 10L, 20L, 30L, 50L, and 100L (as well as small-scale laboratory models).

II. Features of the Double-Walled Glass Reactor

1. Equipped with an explosion-proof motor; the motor operates spark-free, ensuring safety, reliability, and a long service life.

2. The entire set of glassware is manufactured using GG17 high-borosilicate glass, offering excellent chemical and physical properties.

3. Hot oil can be circulated through the glass jacket to facilitate heating reactions, while a cooling fluid can be circulated to conduct low-temperature reactions. For reactions conducted at ambient temperature, circulating tap water through the glass jacket allows for the rapid removal of reaction heat, thereby maintaining a constant temperature.

4. Sealed using PTFE (polytetrafluoroethylene) materials and specialized composite sealing rings; this configuration is resistant to various solvents and capable of maintaining a high vacuum level, making it extremely convenient to use.

5. The bottom discharge port features a PTFE valve design, ensuring there are no "dead spots" within the vessel; it is also detachable, facilitating the easy discharge of solid materials.

6. The reactor lid features a six-port design with an extra-large central opening to facilitate easy cleaning; the standard-sized ports allow for the flexible assembly of various auxiliary devices, such as dropping funnels, condensers for reflux, and distillation apparatus.

7. Features an excellent stirring and sealing system that is both corrosion-resistant and wear-resistant, while effectively maintaining a tight seal within the reactor vessel.

8. Utilizes standardized connection methods that make disassembly extremely convenient. The standard ports on the reactor lid feature ground-glass ball joints; this design minimizes vibration in the glass components while ensuring the safety and flexibility of the glass connections.

9. Includes a dedicated glass thermowell (temperature probe tube); an optional digital temperature display unit is available. This setup ensures real-time temperature feedback while maintaining the integrity of the reactor seal, effectively isolating the thermometer probe from direct contact with the internal reaction mixture to prevent contamination.

10. Features a rational and user-friendly structural design. The stainless steel support frame is mounted on four universal casters, making the unit easy to install and convenient to operate.
