LCD display, it is easier and more convenient to measure the temperature.
Single-layer or double-layer PTFE sheet for stirring, corrosion resistance
The inner layer of the glass reactor can be placed in the reaction solvent to carry out the stirring reaction, and the sandwich can be connected with various cold and heat sources (freezing liquid, hot water or hot oil) to carry out the high-temperature reaction (configured with a corresponding circulating oil bath) or low-temperature reaction (configured with a corresponding low-temperature circulating freezing liquid system, and a heating element can be selected and cooling built-in circulator; Under the condition of establishing a constant temperature, the stirring reaction can be carried out in a closed glass reactor under atmospheric pressure or negative pressure according to the requirements of use, and the reaction solution can be refluxed and distilled, and can be pumped into vacuum to carry out the vacuum reaction. Stirring reaction, and can do the reaction solution refluxed and distilled, the use can be pumped into vacuum to do the vacuum reaction.
It is an ideal pilot test and production equipment for modern fine chemistry, biopharmaceuticals and the synthesis of new materials.
***Please note: glasse reactors with a volume of 1 l, 3 l are supplied only with a temperature tube (without a PT100 temperature sensor)

Pilot-Scale Synthesis Capabilities with the TOPT-3L Jacketed Reactor
You know that awkward phase when your bench-scale reaction works beautifully in a 100mL flask, but you need actual quantities for characterization or the next round of testing? That's where a 3-liter reactor comes in. The TOPT-3L gives you enough volume to make progress without jumping straight to production equipment you might not be ready for yet.
Three-Liter Volume for Mid-Scale Chemical Processing
The double-wall jacket surrounds a 3L working volume, which honestly hits a sweet spot for process development. You're looking at a temperature range from -80°C to 200°C—cold enough for lithium chemistry, hot enough for most condensation reactions you'll run into. The four-neck flask design is practical because you can fit in your addition funnel, thermometer, condenser, and still have a port for sampling or nitrogen line. Stirring goes from 50 to 1500 rpm with a 60W motor that won't stall out when you're working with thick slurries or crystallization mixtures. If you're still doing initial screening work, the TOPT-1L Glass Jacketed Reactor (Double glass reactor) makes sense, but once you've nailed down your conditions, running three batches at 1L gets old fast.
Dual-Jacket Design for Precise Thermal Regulation
Here's where the jacketed construction really pays off—you get even heat distribution without the hot spots that can ruin temperature-sensitive reactions. I'd recommend pairing it with the Cooling circulator Chiller LX-0400 if you're dealing with exothermic additions or need to hold steady at sub-ambient temps. The circulating fluid in that jacket space responds quickly to thermal changes, which matters when you're trying to control runaway reactions or maintain narrow temperature windows.
For vacuum work, you've got options depending on what you need. The Vacuum pump SHB-B95 handles routine distillations and solvent stripping just fine. When you're working with high-boiling solvents or need to pull deeper vacuum for sublimations, grab the Vacuum pump SHB-III instead. The reinforced glass joints hold their seal even when you're running vacuum at elevated temperatures, which isn't always a given with cheaper reactors.
Transitioning from Laboratory Bench to Production Scale
- Geometry consistency: The TOPT series maintains similar vessel proportions across sizes, so your mixing patterns and heat transfer characteristics scale predictably
- Next step up: When 3L batches aren't cutting it anymore, the Glass Jacketed Reactor (Double Glass Reactor) TOPT-5L uses the same accessories and control setup
- Stability during operation: At 25 kg, it stays put during vigorous stirring without needing to bolt it down
- Compliance: CE and ISO certification means it'll pass safety reviews in both academic and industrial settings
The borosilicate glass construction lets you watch your reaction progress visually—you'd be surprised how often that catches problems before your analytics do. It handles thermal shock well and stands up to most aggressive chemistry you'll throw at it.
