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.

Moving Beyond Round-Bottom Flasks: The TOPT-5L Double Glass Reactor
If you've been running reactions in round-bottom flasks with external baths, you know the frustration—uneven heating, temperature overshoots, and constantly watching your setup like a hawk. Jacketed reactors solve this by circulating temperature-controlled fluid through the outer jacket, giving you thermal control that actually makes your data reproducible.
The 5-liter capacity hits a sweet spot for scaling up from benchtop trials without committing to pilot-scale equipment. You're working with borosilicate 3.3 glass, which handles thermal shock way better than standard glass—crucial when you're running exothermic reactions or need rapid temperature changes.
Five-Liter Jacketed Vessel for Enhanced Reaction Control
Temperature range spans -80°C to 280°C, meaning you can handle everything from cryogenic lithium reactions to high-temperature condensations without switching equipment. The stirring system uses an AC induction motor with VVVF drive (50-600 rpm), which maintains consistent torque even as your reaction viscosity changes—you won't get the motor burnout that cheaper DC motors give you.
Key specs you'll care about:
- Working volume: 5 liters (enough for meaningful scale-up)
- Jacket pressure rating: Maximum 0.5 bar
- Power requirements: 220V/50Hz, 60W motor
- Material: Borosilicate 3.3 glass throughout
Compare this to the TOPT-1L Glass Jacketed Reactor (Double glass reactor) if you're doing initial screening work, or the TOPT-3L jacketed glass reactor (double glass reactor) for mid-range synthesis. The 5L model gives you room to scale while maintaining precise control.
Superior Temperature Stability Compared to External Bath Methods
The double-jacket design works by circulating fluid from an external temperature control unit through the space between inner and outer glass walls. Pair this reactor with a Cooling circulator Chiller LX-0400 for reactions requiring sub-ambient temperatures—the chiller maintains consistent fluid temperature while the reactor's jacket distributes it evenly around your reaction mixture.
You'll use this setup for synthesis reactions where temperature control directly affects yield and selectivity. Distillations benefit from the controlled heating and the overhead condenser ports. For crystallizations, you can program slow cooling curves that produce better crystal habits than ice baths ever could. The variable-speed stirring prevents hot spots and ensures uniform mixing, which matters when you're dealing with heterogeneous catalysts or viscous reaction mixtures.
Integrated Design for Efficient Chemical Synthesis
Vacuum operations require coupling with either the Vacuum pump SHB-B95 for general vacuum work or the Vacuum pump SHB-III for deeper vacuum requirements during distillations or solvent removal. The pressure relief valves aren't just regulatory checkboxes—they're your protection when reactions go faster than expected.
Pro tip: Always verify your chiller capacity matches the reactor's heat load. An undersized chiller can't remove heat fast enough during exothermic reactions, defeating the purpose of jacketed design. Check all ground glass joints for chips before assembly—a small crack becomes a vacuum leak or worse during operation. The emergency release mechanism lets you quickly depressurize without disassembling hot glassware, which you'll appreciate when things get exciting.
