Single Layer Glass Reactor 3.3 Borosilicate Laboratory Chemical Synthesis Vessel with Overhead Stirrer

The single layer glass reactor is an economical yet highly capable solution for laboratories and small-scale production facilities that require reliable reaction performance without the complexity of jacketed systems. Designed around a robust single-wall borosilicate glass vessel, this reactor delivers straightforward heating via an external bath or heating mantle, making it the ideal choice for routine synthesis, mixing, and simple distillation tasks. Its transparent construction provides full visual access to the reaction progress, enabling researchers to monitor color changes, phase separation, and precipitate formation in real time without interrupting the process.

Engineered with practicality in mind, this single layer reactor features a cylindrical vessel with a flat or round bottom configuration, depending on volume and application requirements. The vessel is formed from 3.3 high borosilicate glass, ensuring compatibility with a broad spectrum of chemicals including strong mineral acids, alkaline solutions, and polar organic solvents. The glass surface is non-porous and easy to clean, minimizing carryover contamination between experiments. For temperature control, the vessel is placed in a compatible water bath, oil bath, or heating mantle, providing flexible heating options that adapt to existing laboratory infrastructure.

The stirring mechanism employs an overhead electric motor coupled to a PTFE stirring shaft and impeller. The motor is mounted on a vertical support rod with adjustable height positioning, allowing the impeller to be set at the optimal depth for the reaction volume. Speed regulation is accomplished through a solid-state controller with a continuously variable dial, providing smooth acceleration from gentle 50 rpm mixing to vigorous 600 rpm agitation. The PTFE stirring components are chemically inert and resistant to swelling, ensuring long service life across diverse solvent systems.

Versatility is enhanced through a multi-neck lid design that accommodates additional glassware such as reflux condensers, dropping funnels, thermometers, and sampling ports. The standard ground-glass joints are precision-manufactured to ensure vacuum-tight seals without the need for excessive grease. A bottom drain valve with PTFE plug facilitates complete product recovery and simplifies cleaning between batches. The entire assembly is mounted on a powder-coated steel support stand with a stable base plate, designed to remain steady during high-speed stirring without drifting or vibrating.

• Cost-Effective Single Wall Design: Simplified reactor geometry reduces capital investment while maintaining excellent chemical compatibility and visual transparency, ideal for teaching laboratories and routine synthesis workflows.
• Versatile External Heating Compatibility: Designed to operate seamlessly with standard laboratory water baths, oil baths, and heating mantles, allowing users to leverage existing thermal equipment without specialized jacket circulation systems.
• Full Visual Reaction Monitoring: Crystal-clear borosilicate glass construction provides unobstructed observation of reaction dynamics including color transitions, precipitate formation, and phase behavior throughout the entire process.
• Adjustable Overhead Stirring System: Variable-speed motor with height-adjustable mounting bracket ensures precise impeller positioning and consistent mixing performance across different fill volumes and viscosities.
• Multi-Neck Modular Configuration: Standardized ground-glass joints accept reflux condensers, addition funnels, and monitoring probes, enabling the reactor to be quickly reconfigured for diverse experimental protocols.
• Easy Cleaning and Maintenance: Smooth glass surfaces and a bottom PTFE drain valve allow rapid draining and thorough cleaning, minimizing downtime between consecutive reactions and preventing cross-contamination.

The single layer glass reactor is the workhorse of undergraduate chemistry laboratories, where it introduces students to fundamental reaction techniques including reflux, simple distillation, and liquid-liquid extraction. In quality control departments of pharmaceutical and food processing companies, it performs routine assays, dissolution testing, and sample preparation with consistent reliability. Small-scale specialty chemical producers use these reactors for batch synthesis of intermediates, colorants, and fine chemicals where process simplicity and rapid turnaround are paramount. Environmental testing laboratories deploy them for sample digestion and extraction procedures in compliance with EPA and ISO methods. Biotechnology startups appreciate the low entry cost and straightforward operation for early-stage process feasibility studies and proof-of-concept synthesis campaigns before scaling up to jacketed pilot systems.

Each single layer reactor undergoes visual inspection for glass defects, dimensional verification of ground-glass joints, and pressure testing of assembled components prior to packaging. All glass parts are individually cushioned with anti-static foam sleeves and partitioned within heavy-duty corrugated cartons. The motor unit and support stand are packaged separately in reinforced boxes with molded pulp cushioning. Fumigated plywood outer cases are used for multi-unit shipments or export orders to ensure compliance with ISPM 15 phytosanitary standards. A 12-month warranty against manufacturing defects is standard, and our service team is available for remote troubleshooting and spare parts supply. Detailed assembly instructions with annotated diagrams are included to facilitate rapid setup and safe operation.
