TECHTONGDA 20L Jacketed Reactor Double‑Layer Glass Digital Display

Description

Product Overview

The TECHTONGDA 20L Jacketed Reactor is engineered for demanding laboratory environments where precision, durability, and safety are paramount. Constructed from GG‑17 high‑borosilicate glass, the double‑layer vessel offers exceptional resistance to thermal shock, chemical corrosion, and mechanical stress, making it suitable for a wide range of reactions from ambient temperature to high‑temperature distillations. The outer jacket circulates temperature‑controlled fluid, allowing users to maintain exact reaction temperatures while minimizing heat loss.

Key structural components include a stainless‑steel frame that provides robust support and easy handling, and a PTFE rotary sealing assembly that guarantees an airtight environment, high vacuum capability, and long service life even under aggressive chemical exposure. The integrated digital speed controller, accessible via a user‑friendly knob, delivers adjustable stirring speeds ranging from 50 to 500 RPM, enabling fine‑tuned mixing for both gentle dissolution and vigorous agitation.

Additional features such as the 110 V power supply, a built‑in temperature sensor, and a clear digital display ensure that operators can monitor and adjust critical parameters in real time. The reactor’s dimensions (19.69 × 22.44 × 81.5 in) and weight (196 lb) provide a stable platform while still fitting comfortably on standard laboratory benches.

Usage

This reactor excels in a variety of laboratory applications, including organic synthesis, polymerization, catalyst testing, and biopharmaceutical formulation. Researchers can employ it for small‑scale pilot studies, medium‑scale batch processes, or as a teaching tool in academic settings. The double‑layer design enables simultaneous heating and cooling, allowing for reflux, distillation, and crystallization procedures without the need for additional external equipment.

Because the PTFE rotary seal is compatible with strong acids, bases, and solvents, the reactor can safely handle aggressive reagents such as concentrated sulfuric acid, sodium hydroxide, and organic solvents like dichloromethane or tetrahydrofuran. The digital speed controller ensures reproducible mixing conditions, which is critical for kinetic studies, scale‑up experiments, and quality‑controlled production runs.

Safety-conscious laboratories appreciate the built‑in over‑temperature protection and the ability to maintain a closed system, reducing the risk of exposure to hazardous vapors. The reactor’s transparent glass construction also allows for visual monitoring of reaction progress, color changes, and precipitate formation without interrupting the process.

FAQ

What types of reactions are best suited for this reactor?

The reactor is ideal for synthesis, distillation, reflux, crystallization, and biopharmaceutical formulation where precise temperature control and reliable mixing are required. Its chemical‑resistant glass and PTFE seal allow it to handle a broad spectrum of reagents.

Can the reactor be integrated with external temperature controllers?

Yes, the outer jacket is designed to connect to standard circulating water or oil baths, as well as digital temperature controllers. This flexibility lets users achieve exact temperature set‑points for both heating and cooling applications.

How do I maintain the PTFE rotary seal for long‑term performance?

Regular cleaning with compatible solvents, avoiding abrasive materials, and periodic inspection for wear are recommended. The seal can be replaced by qualified service personnel if any signs of degradation appear.

Is the digital display calibrated out of the box?

The display is factory‑calibrated to ensure accurate speed readouts. Users can perform a quick verification using a calibrated tachometer, and the controller can be fine‑tuned if necessary.

What safety features are included to prevent overheating?

The reactor incorporates an over‑temperature sensor that triggers an automatic shutdown of the heating element if the set temperature is exceeded, protecting both the equipment and the user.
