They maintain thermal stability using a jacketed layer for fluid circulation without exposing the medium. Their borosilicate glass build withstands thermal stress and chemical exposure over time. These systems include a display panel for monitoring key parameters during operation. Our glass reactor is suited for synthesis, distillation, extraction, crystallization, and pharmaceutical development.








Our Jacketed Glass Reactor LJGR-B13 is designed with multiple lid access points that support independent integration of feeding lines, pressure monitors, and reflux setups. The separation between these openings allows users to operate various components without obstruction or interference. Its wide central port enables the use of larger-scale equipment like stirrer shafts or reflux condensers. Additional side openings accommodate sampling ports or inline sensors, ideal for time-based monitoring. This setup reduces the need to pause the reaction or open the lid for interventions. Inputs and sampling can occur without breaking containment or altering the internal environment. The reactor maintains a stable configuration even when loaded with auxiliary attachments. This versatility makes it suitable for staged processes, multi-step reactions, and real-time quality testing.
The Jacketed Glass Reactor LJGR-B13 incorporates a bottom-mounted drain system that safely directs liquid waste or residuals into collection containers without needing vessel tilting or disassembly. Its elevated clearance allows drip-free drainage, especially useful when handling chemically active or volatile solutions. The outlet is aligned with the base of the vessel to eliminate pooling and reduce the need for manual scraping. During long-running reactions, this drains port offers a clean method to remove intermediates or harvest samples without stopping the process. It minimizes the risk of spills, burns, or contamination during transfer. Safety is improved with hands-free discharge that avoids sudden splashes or pressure buildup. It’s especially beneficial in labs handling high-viscosity or temperature-sensitive fluids. This draining system supports clean exits and efficient turnover between batch runs.
Labtron’s Jacketed Glass Reactor LJGR-B13 is equipped with insulation-ready hose ports and a double-jacketed body to prevent direct thermal shock to the glass when switching between hot and cold circulation fluids. Its thermal buffer zones absorb heat differentials and reduce sudden expansion or contraction within the reactor wall. This capability is important when alternating processes such as heating for reaction activation and cooling for crystallization. Temperature fluctuations are balanced through uniform fluid flow, ensuring that the internal environment does not experience hotspots. The system avoids strain on the vessel structure over repeated cycles. This protects both the reactor and the chemical yield from temperature inconsistencies. The unit supports tight control during stepwise reactions involving thermal variation. It’s ideal for protocols that transition between exothermic and cooling phases.
Our Jacketed Glass Reactor LJGR-B13 supports a wide range of viscosities, allowing researchers to conduct mixing operations involving resins, gels, and slurries without material buildup or stagnation. Its overhead stirring mechanism provides stable mixing at variable speeds, ensuring complete phase blending even when densities differ significantly. Internal geometry promotes full circulation, preventing heavier compounds from settling at the bottom. The agitator shaft handles load variation without causing strain on the drive. It’s also helpful for emulsion preparation and dispersion of solid particles in liquids. The system avoids shear hotspots and reduces dead zones that usually occur in high-viscosity media. Phase separation is minimized, even under long runtime conditions. It enables uniform material distribution across the reaction cycle without mechanical or chemical compromise.
Jacketed Glass Reactor LJGR-B13 provides several upgrade paths, including optional explosion-proof motors, reinforced control boxes, and compatible collection trays that can be integrated without altering the core structure. Its modular architecture allows users to add safety enclosures or replace standard parts with advanced configurations tailored to hazardous environments. Depending on process requirements, extended condensers or baffle accessories can be connected through existing lid ports. The reactor’s electrical and mechanical components are positioned to allow independent shielding. These additions enable compliance with stricter industry standards such as those in pharmaceutical or petrochemical fields. The design supports both operator protection and process enhancement. Users working with reactive agents benefit from better containment and safer handling. This flexibility makes the system scalable from R&D to pre-production pilot projects.
The Jacketed Glass Reactor LJGR-B13 is mounted on a reinforced frame with anti-vibration features that reduce micro-movement during stirring, temperature changes, or equipment operation nearby. The support base absorbs shocks from the surrounding environment, preserving the internal reaction stability. This is crucial for crystallization or polymerization processes that are sensitive to agitation levels. Even under high-speed stirring, the reactor avoids vibration feedback that could alter phase behaviour or product structure. Sensors mounted on the vessel retain accuracy due to reduced oscillation. The structure allows delicate processes to proceed undisturbed for extended durations. This is especially helpful in labs with multiple machines running in parallel. It protects both reaction yield and measurement reliability throughout the experiment.
