Engineered with a dual-layer precision design, this vacuum chemical reactor is a high-end system that integrates stirring, heating/cooling, reflux, and distillation. The internal vessel is designed for reaction solvents, while the jacketed layer allows for the circulation of thermal sources such as refrigerants, hot water, or thermal oil. This versatile chemical reactor supports both atmospheric and negative pressure (vacuum) stirring under airtight, constant-temperature conditions. It serves as a vacuum reactor or high-performance stainless steel autoclave for the chemical, pharmaceutical, and biotechnology research sectors.

Core Value Propositions

---

• Extreme Temperature Versatility: Engineered to withstand extreme experimental conditions ranging from -120°C to 300°C. This high-temperature vacuum chemical reactor unit serves as a high-performance “all-in-one” solution for both cryogenic synthesis and high-heat reactions.
• Stable Vacuum Performance: Features a reinforced airtight structure and advanced mechanical seals. In a static state, it reliably maintains high vacuum levels, making it ideal for moisture-sensitive or low-boiling-point solvent recovery.
• Intelligent VFD Stirring: Equipped with a variable frequency constant-speed system and digital display. This ensures uniform torque and smooth, consistent mixing even during high-viscosity chemical processes.
• Premium Anti-Corrosion Setup: Outfitted with single or double-layer PTFE impellers and a zero-dead-space discharge valve. This configuration minimizes residue, prevents contamination, and extends the equipment’s service life.

Primary Application Scenarios

---

Advanced Chemical & Bio-R&D: The premier choice for research institutes performing specialized chemical synthesis, biological processing, and complex academic experiments.

Pharmaceutical Refining: Optimized for the extraction, purification, and high-vacuum concentration of sensitive herbal extracts or active pharmaceutical ingredients (APIs).

Fine Chemical Production: Facilitates precision constant-temperature stirring, reflux, and distillation within standardized industrial chemical workflows.

Food & Beverage Engineering: Meets strict industry hygiene requirements while providing the precise thermal control needed for food-grade material reactions.

Solutions to Critical Technical Challenges

---

• Managing Wide Thermal Gaps: Unlike conventional reactors that fail at temperature extremes, our jacketed system supports a total range of 420°C, providing a single platform for diverse research.
• Eliminating Batch Contamination: By utilizing a zero-dead-space discharge valve, the system ensures 100% material discharge and prevents liquid accumulation at the outlet.
• Ensuring Vacuum Reliability: Precision-machined lid ports and mechanical seals prevent air leakage under negative pressure, ensuring the repeatability of high-vacuum experiments.
• Resisting Aggressive Media: For acidic or alkaline reactions, the combination of a stainless steel vessel and PTFE-coated internals offers superior resistance compared to standard industrial mixers.
