1.Double Glazed Reactor What is it?
The double glazed reactor — also called double layer jacketed glass reactor or simply jacketed glass reactor — is one of the most commonly used temperature-controlled stirred reaction vessels in chemical, pharmaceutical, and fine chemical laboratories during the small-scale (lab-scale) testing phase. This 1L model uses high-borosilicate glass as the main body with a double-layer jacket structure. By circulating heating or cooling medium through the jacket, it enables precise temperature control of the reaction system. It is suitable for a wide variety of chemical processes including low-temperature, high-temperature, vacuum, reflux, and more.
2. What problems does it solve for you?
- Unstable temperature control, large fluctuations, or thermal shock cracking of glass under extreme conditions
- Poor mixing uniformity, sedimentation at the bottom, local overheating, or incomplete reactions
- Leakage issues, contamination, or inability to maintain vacuum due to poor sealing
- Small-scale experimental data that cannot be reliably scaled up to pilot or production, leading to repeated trials, high development costs, and project delays
- Difficult cleaning and stubborn residues after reaction that affect the next experiment
- Safety risks when handling flammable or explosive solvents, plus high energy consumption and heat loss during long runs
With precise temperature control, efficient stirring, flexible multi-port design, and optional safety upgrades, it helps you obtain reliable, reproducible experimental data — greatly reducing risks and costs when moving from lab-scale to process scale-up.
3. What are the product features?

Application Scenarios
- Pharmaceutical Intermediate Synthesis & Process Optimization Used in early-stage drug development for small-scale synthesis of key intermediates requiring strict temperature control and uniform mixing. The -120°C to +300°C range and efficient stirring ensure high reproducibility and accelerate process development.
- Low-Temperature Grignard & Organometallic Reactions Many organic syntheses require temperatures as low as -78°C or below. This reactor supports ultra-low stable operation with a fluorine-coated paddle resistant to highly reactive reagents, avoiding thermal shock issues common in conventional setups.
- High-Temperature Synthesis & Solvothermal Reactions Ideal for polymerization, solvothermal reactions, and other high-temperature processes up to +300°C. The wide temperature range combined with optional insulation jacket minimizes heat loss and maintains energy efficiency.
- Distillation, Reflux & Solvent Recovery Connect condensers and receivers for atmospheric or reduced-pressure distillation and solvent recycling. Five customizable ports enable flexible setups for reflux, vacuum filtration, and more.
- Crystallization Process Control & Optimization Crystallization is highly sensitive to temperature gradients and stirring speed. Precise PT100 temperature control and 0–1350 rpm variable stirring allow fine-tuned supersaturation and crystal form control for higher purity and yield.
- Lab-to-Pilot Scale Process Validation Generates reliable, reproducible data in the lab to support confident scale-up to pilot/production. The compact 1L size is easy to handle, with parameters directly comparable to larger models in the same series.
- Other Specialized Reactions Suitable for photocatalysis (with light source port), gas-liquid reactions, multi-step continuous reactions, etc., thanks to highly customizable port configurations.
