How the Vacuum Rotary Evaporator Enhances Efficiency in Chemical and Pharmaceutical Industries
2025-10-29
The Vacuum Rotary Evaporator has become an essential instrument in modern chemical, pharmaceutical, and biological laboratories. Designed for concentration, crystallization, drying, separation, and solvent recovery, this innovative device significantly improves productivity and safety in research and production environments.
By operating under vacuum conditions, the Vacuum Rotary Evaporator enables solvent evaporation at lower temperatures. As the rotating flask spins at a constant speed, the material spreads into a thin film across the inner wall, increasing surface area and accelerating evaporation. The evaporated solvent vapor is then condensed through a high-efficiency glass condenser and collected for reuse — offering exceptional solvent recovery and energy savings.
Manufactured by Nantong Sanjing Chemglass Co., Ltd., the Vacuum Rotary Evaporator stands out with its customizable design and intelligent features. The explosion-proof motor ensures maximum safety, while the automatic lifting bath and vacuum feeding system minimize glass breakage. The advanced temperature control system works with both water and oil baths, maintaining a precise stability of ±0.02°C for consistent evaporation.
The product lineup includes models from 2L to 50L capacity (PR-2, PR-5, PR-10, PR-20, and PR-50), meeting the diverse needs of laboratory and industrial users. Each Vacuum Rotary Evaporator model is built with high-quality glassware, durable motors, and corrosion-resistant materials to guarantee long-term performance.

How to Choose the Right Chemical Glass Reactor for Your Application?
2025-10-28
What Is a Chemical Glass Reactor?
A chemical glass reactor is a transparent vessel made from borosilicate glass, allowing operators to observe reactions in real time. It’s used for mixing, heating, cooling, distilling, and crystallizing chemical compounds under controlled conditions.
The reactor can handle vacuum or pressure, and is compatible with most solvents, acids, and bases — making it ideal for pharmaceutical R&D, fine chemicals, and laboratory synthesis.
Key Factors to Consider When Choosing a Chemical Glass Reactor
1. Capacity and Scale
Choose the reactor size according to your process volume and application type:
Lab-scale reactors: 1L – 20L for research and small-batch testing
Pilot-scale reactors: 30L – 100L for intermediate process development
Industrial-scale reactors: 100L – 500L+ for production use
If you plan to scale up later, choose a model compatible with modular expansion or upgrade options.
2. Type of Reactor Design
There are several common designs, each suited for specific needs:
Single-Layer Glass Reactor: Used mainly for simple mixing or reactions at room temperature.
Jacketed Glass Reactor (Double-Layer): Includes a jacket for circulating heating/cooling fluids — ideal for temperature-sensitive reactions.
Triple-Layer Glass Reactor: Offers additional insulation and efficiency for high-precision temperature control.
Tip: For processes that require heating and cooling cycles, a jacketed reactor is the best choice.
3. Temperature and Pressure Requirements
Check the working temperature range (typically -80°C to +250°C) and whether your reaction requires vacuum operation or positive pressure.
Ensure the glass material and sealing components can handle your process conditions safely.
4. Material and Chemical Compatibility
Use borosilicate 3.3 glass for excellent resistance to acids, bases, and solvents.
Verify that the gaskets, valves, and joints are made of PTFE or stainless steel for durability.
5. Stirring and Mixing System
Different reaction types require different agitator designs (propeller, anchor, paddle, or turbine).
Look for a variable-speed motor and stable stirring mechanism to ensure homogeneous mixing and prevent sedimentation or localized overheating.
6. Additional Features and Accessories
Consider useful add-ons such as:
Condensers for reflux or distillation
Vacuum pumps for solvent removal
Temperature and pressure sensors
Control systems with digital displays or automation options
Typical Applications of Chemical Glass Reactors
Chemical glass reactors are widely used in:
Pharmaceutical synthesis and formulation
Organic and inorganic chemical research
Crystallization and extraction processes
Polymer and resin production
Material science and nanotechnology experiments
Choosing the right Chemical Glass Reactor depends on your process requirements, scale, and temperature control needs.
A jacketed glass reactor is ideal for precise thermal reactions, while a single-layer reactor suits basic lab processes.
When in doubt, consult an experienced manufacturer like Wuxi Fenigal Science and Technology Co., Ltd., which provides customized, OEM-ready glass reactors designed for durability, safety, and performance.

What Is a Chemical Glass Reactor and How Does It Work?
A Chemical Glass Reactor is a specialized vessel used to mix, react, heat, cool, and crystallize chemicals under controlled conditions. It’s a core piece of equipment in pharmaceutical, chemical, and research laboratories, providing excellent visibility and chemical resistance for precise reaction control.
What Is a Chemical Glass Reactor?
A chemical glass reactor is typically made of borosilicate glass, known for its durability and resistance to corrosion, acids, and temperature shocks.
It allows chemists and engineers to visually monitor reactions while maintaining complete control over temperature, pressure, and mixing speed.
These reactors are available in various sizes — from 1 liter for laboratory use to 200 liters or more for pilot and industrial production.
How Does a Chemical Glass Reactor Work?
A standard glass reactor system is composed of several key parts that work together to create a safe and stable reaction environment:
1. Jacketed Glass Vessel
The reactor features a double-layered (jacketed) wall that allows a heat-transfer fluid (such as oil or water) to circulate.
This enables precise heating or cooling of the reaction mixture.
The temperature can range from -80 °C to +250 °C, depending on the process.
2. Stirring System
A motor-driven stirrer mixes the reactants evenly, improving reaction uniformity.
Variable-speed control ensures optimized mixing for different viscosities and reaction types.
3. Condensers and Reflux System
Glass reactors often include a condenser for distillation or reflux operations, allowing continuous reactions without loss of solvent.
4. Vacuum and Pressure Control
The system can operate under vacuum to remove gases or solvents, or under pressure for certain synthesis reactions.
5. Observation and Sampling
Because the reactor body is transparent, operators can visually observe phase changes, color shifts, or precipitation in real time.
Sampling ports make it easy to test reaction progress safely.
Common Applications
Chemical glass reactors are widely used in:
Chemical synthesis and polymerization
Pharmaceutical R&D and intermediate production

What is a jacketed glass reactor used for?
2025-10-28
What Is a Jacketed Glass Reactor?
A jacketed glass reactor consists of a borosilicate glass vessel with a double-layer (jacketed) wall. The outer jacket allows a heating or cooling fluid (like water, oil, or glycol) to circulate around the inner vessel. This design provides accurate temperature control for the reaction materials inside.
The vessel is usually mounted on a steel frame with stirring mechanisms, temperature sensors, and control systems, allowing researchers to conduct reactions safely and efficiently.
How Does a Jacketed Glass Reactor Work?
Temperature Control
A thermal fluid (heating or cooling medium) is pumped through the jacket.
Heat exchange occurs through the glass wall, maintaining a stable internal temperature.
This is ideal for reactions requiring precise thermal conditions, from -80°C (for cooling) to +250°C (for heating).
Mixing & Stirring
The reactor includes a mechanical or magnetic stirrer driven by a motor.
It ensures uniform mixing, improving reaction efficiency and consistency.
Vacuum or Pressure Operation
Many jacketed reactors can operate under vacuum conditions to remove solvents or gases, or under pressure for certain synthesis reactions.
Observation & Safety
The transparent borosilicate glass allows operators to visually monitor the reaction process in real time.
The glass material is chemical-resistant and thermal shock–resistant, ensuring safety and longevity.
