50L Explosion-Proof Double-Jacketed Glass Reactor

Introduction to the 50L Double-Layer Glass Reactor

The glass reactor features a double‑walled design: the inner jacket holds the reaction solvent and enables stirred reactions, while the interlayer can be connected to various heating or cooling sources—such as refrigerant, hot water, or thermal oil—to provide circulating heating or cooling. Under precisely controlled temperature conditions, this sealed glass reactor allows for stirred reactions at atmospheric or reduced pressure, depending on operational requirements, and supports reflux and distillation of reaction mixtures. It is an ideal pilot‑scale and production‑scale apparatus for modern fine chemical synthesis, biopharmaceutical manufacturing, and new materials development.

50L double‑walled glass reactor is an experimental and pilot‑scale apparatus widely used in fields such as chemistry, biopharmaceuticals, and new materials synthesis. Its core functions—precise temperature control, stirring, and visual operation—are achieved through a double‑walled glass structure, making it suitable for sealed reactions under both high‑temperature conditions (up to 300°C) and low‑temperature conditions (as low as −80°C).
