1. What is it?

The jacketed glass reactor — also known as double layer jacketed glass reactor — is a core piece of equipment for temperature-controlled stirred reactions in chemical, pharmaceutical, and fine chemical laboratories, especially during small-to-medium scale testing. This 2L model features a high-borosilicate glass body with a double-layer jacket structure. By circulating heating or cooling medium through the jacket, it provides accurate and stable temperature control for a wide range of chemical processes, including low-temperature, high-temperature, vacuum, reflux, and more.

2. What problems does it solve for you?

Temperature instability, fluctuations, or thermal shock cracking under extreme conditions — especially critical when handling larger reaction volumes
Uneven mixing, bottom sedimentation, local overheating, or incomplete reactions — issues that become more pronounced with increased material volume and are effectively addressed by the powerful, high-torque stirring system
Leakage, contamination, or vacuum loss due to sealing failures during longer or higher-volume runs
Lab-scale data that is too small to reliably predict pilot-scale behavior, leading to costly repeated trials and scale-up failures
Insufficient sample size for meaningful process optimization or yield assessment in small-to-medium experiments
Difficult post-reaction cleaning and persistent residues when dealing with larger quantities of material
Safety risks when scaling up flammable or explosive reactions, plus higher energy consumption and heat loss in extended operations

This 2L jacketed glass reactor provides more representative reaction conditions than smaller models, delivering reliable, reproducible data that bridges lab-scale experiments to pilot-scale development — significantly reducing risks, trial-and-error costs, and time-to-market for chemical and pharmaceutical processes.

Application Scenarios

Pharmaceutical Intermediate Synthesis & Process Optimization Used in early- to mid-stage drug development for small-to-medium scale synthesis of key intermediates and APIs. The ultra-wide temperature range and precise PT100 control ensure high reproducibility and purity while accelerating process development and scale-up decisions.
Low-Temperature Grignard & Organometallic Reactions Essential for reactions requiring sub-zero temperatures (e.g., -78°C or lower). The reactor’s stable cryogenic performance, combined with the fluorine-coated paddle’s resistance to reactive reagents, prevents thermal shock and delivers safe, controlled results.
High-Temperature Synthesis & Solvothermal Reactions Ideal for polymerization, solvothermal synthesis, and other high-heat processes up to +300°C. Optional insulation jacket minimizes heat loss, maintaining uniform temperature and improving energy efficiency during extended runs.
Distillation, Reflux & Solvent Recovery Connect condensers, receivers, and vacuum lines for atmospheric or reduced-pressure distillation and efficient solvent recycling. The 5 customizable ports allow seamless integration of reflux, fractionation, and collection setups.
Crystallization & Precipitation Control Critical for achieving high-purity crystals with controlled crystal size and morphology. Precise temperature gradients and variable-speed stirring (0–1350 rpm) enable fine-tuned supersaturation and reproducible crystallization outcomes.
Extraction, Purification & Multi-Step Reactions Supports solvent extraction, phase separation, and sequential reactions. Flexible port configuration makes it easy to add feeding systems, sampling ports, or gas inlets for complex, multi-stage processes.
Lab-to-Pilot Scale Process Validation Generates representative data at 2L scale that bridges lab experiments to pilot/production. This reduces risks of scale-up failure, minimizes costly re-optimization, and shortens time-to-market for new chemical or pharmaceutical processes.
