Double glass vacuum glass reactor, the inner layer is filled with reaction solvent to carry out the mixing reaction, various hot and cold substances (frozen liquid, hot water or hot oil) can be added to the inner layer to carry out the heating or cooling reaction. This glass jacket reactor can be used for both high temperature experiment (maximum temperature 280°C) and low temperature experiment (minimum temperature -80°C) and vacuum test.
Features of 5L Double Glass Reactor:
1. Use PTFE composite seal, it can maintain high vacuum degree.
2. Use efficient condenser to ensure high recovery rate.
3. The full set of glass uses GG17 high borosilicate glass with good chemical and
physical properties.
4. The interlayer interface glass is added with hot oil, through the loop, it can make the reaction
under the condition of high temperature; glass interlayer interface added with cooling
liquid can carry out the reaction under low temperature condition.
5. Tap water can be added into it to quickly remove the reaction heat.
6. The discharged material has a flange hole and PTFE valve, no dead angle inside the container
6. The discharged material has a flange hole and PTFE valve, no dead angle inside the container, can be dismantled to facilitate the discharge of solid materials.
7. Digital mixing motor, high-speed mixing conversion controlFrequencies, matched with torque-increasing
reducer.
8. Reasonable structure and selected materials. Mechanical components use stainless
steel and aluminum alloys, glass parts use high borosilicate glass with high
heat resistance and good chemical properties. Electrical components:
main components use original imported devices

Glass Jacketed Reactor (Double Glass Reactor) TOPT-5L
The TOPT-5L is a double-walled glass reactor designed for controlled mixing reactions across a wide temperature range. Its inner reaction cylinder holds 5L of solvent, while the surrounding jacket accepts a circulating thermal medium — frozen liquid, hot water, or hot oil — to heat or cool the contents during the reaction. The full glass assembly is constructed from GG17 (3.3) high borosilicate glass, chosen for its strong chemical resistance and physical durability. The unit supports high-temperature work, low-temperature work, and vacuum testing in a single setup.
Temperature, Mixing and Vacuum Performance
The jacketed design allows reactions to be carried out from -80°C to 280°C. Hot oil circulated through the interlayer enables high-temperature reactions, while cooling liquid in the same interlayer supports low-temperature experiments. Note that the PTFE stirrer is rated to withstand approximately 200°C, which should be considered when planning high-temperature runs. Tap water can also be circulated through the jacket to quickly remove reaction heat.
Mixing is driven by a 60W digital motor providing an actual speed range of 50 to 600 rpm, matched with a torque-increasing reducer for stable agitation. A PTFE composite seal maintains a high vacuum degree throughout operation, and an efficient condenser supports a high recovery rate for distilled or evaporated solvents. The reactor runs on a 220V 50Hz/60Hz power supply.
Construction and Handling
The reactor body is engineered with practical handling in mind. The discharge port features a flange hole and a PTFE valve, with no dead angle inside the vessel, and it can be dismantled to ease the removal of solid materials. Mechanical components use stainless steel and aluminum alloys, while the glass parts use high borosilicate glass for heat resistance and chemical compatibility. The main electrical components use original imported devices.

Typical Applications and Related Equipment
This reactor suits synthesis, mixing, distillation, and vacuum reactions in research and pilot-scale laboratory settings. Laboratories that need smaller capacity for preliminary work or for combining with standard Round-Bottom Flasks may consider the 1L model in the same family. Those scaling between sizes can compare it with other jacketed reactors such as the 3L version. To circulate a heated or chilled temperature-controlled fluid through the jacket and reach the lower end of the temperature range, a matching recirculating chiller can be paired with the reactor.
