The S212-200L double-layer glass reactor is a great and innovative product among existing glass reactors of Lanphan, which has combined advantages of similar products at home and abroad. The volume of its reaction flask is 200L, and the interlayer volume is 28L. The diameter of the stirring shaft is 15mm, and the stirring power is 750W. It adopts double-layer glass design. The reaction solvent can be put in the internal layer to do the stirring reaction, and different cold and heat sources (refrigerating fluid, hot water or oil) can be connected to the interlayer for doing circulating heating or cooling reaction. Under the condition of the given constant temperature, the stirring reaction can be done under normal or negative pressure in a closed glass reactor, as well as the backflow and distillation of the reaction solution.

The S212-200L double-layer glass reactor is an ideal pilot-plant and production equipment for modern fine chemical industry, biopharmaceutical and new material synthesis. This series glass reactors mainly consist of following parts: the double-layer glass reaction kettle, a set of component cover of the glass reactor, condensers, a constant voltage funnel, a variable frequency controller, the rotary stirring and sealing system, the stainless steel frame system, etc.

Product Features

1.Constant rotating speed, no brushes, no sparks, good safety and stability, and continuous operation.

2.The complete set of glassware is made of G3.3 borosilicate glass, with excellent chemical and physical properties.

3.The heating reaction can be carried out by connecting the interface of the glass interlayer to the hot oil for circulating, and the low temperature reaction can be done by connecting to the refrigerating fluid.

4.It can react at room temperature and take away the reaction heat rapidly by running water.

5.The lower discharge port is equipped with flange and PTFE valves. There is no dead corner in the vessel. It’s convenient for solid materials to discharge because of the detachable feature.

6.The main body is made of stainless steel, which is elegant and corrosion resistant.

7.The PTFE sealing of components can maintain a relatively high vacuum.

8.It can work under normal and negative pressure, and the negative pressure can reach to -0.098MPa.

9.The AC motor can achieve the variable frequency and speed control stirring, with a stable and reliable operation, large torque and no spark.

10.The stirring rod of the S212-200L double-layer glass reactor specially adopts 321 stainless steel, enhancing the ability of corrosion resistance. With the military technology, it has a more exquisite workmanship and more convenient operation.

Product Application

The Lanphan S212-200L double-layer glass reactor is an ideal pilot-plant and production equipment for modern fine chemical industry, biopharmaceutical and new material synthesis. It is convenient to control the reaction process due to the pharmaceutical reaction process can be observed clearly.

The S212-200L double-layer glass reactor can carry out the following experiments:

1.Vacuum stirring reaction;

2.High and low temperature reaction;

3.Mixing reaction at constant speed;

4.Distillation, reflux and concentration;

5.Negative pressure operation, and liquid separation function;

6.The rectification can be carried out by assembling rectifying columns;

7.Concentration has a good technological effectfor plant extraction;

8.It has a obvious effect to equip with the liquid separation device for stirring and separation;

9.The reaction and production of ultra-fine powder can be carried out, which is visible and clean as a kind of sanitary grade production of medicine.

10.Itcan replace rotary evaporators to concentrate high purity materials. The reaction time can be exponentially reduced by matching with the ultrasonic stirring.

11.It’s convenient and simple to operate for both separation and synthesis.


Q: What’s the difference between single-layer and double-layer glass reactors?

A: The single-layer glass reactor can directly heat or cool, which is similar to the water and oil bath. But it’s inferior in temperature control aspect. The double-layer glass reactor has interlayer between two layers. The water or oil can be injected through the temperature control equipment to form a circulating system. It will have a better and more accurate temperature control whether for heating or cooling.

Q: Which one to choose, single-layer glass reactor or double-layer glass reactor?

A: It depends on their differences, heating and cooling conditions.

Q: What is the glass material of the reactor?

A: Full set of glass part adopts G3.3 borosilicate glass, with excellent chemical and physical properties.

Q: What kind of circumstance is it applicable for?

A: It is applicable for a wide temperature range from -80℃ to 200℃.

Q: Is it easy to clean the reaction kettle?

A: It is convenient to clean with the large cleaning port.

Q: What kind of payment terms do you accept?

A: Normally we accept TT, Paypal, Western Union, Alibaba Escrow, and L/C. The exact term will be discussed during the deal.

Q: How will you delivery these goods?

A: It will depend on your quantity. Normally we will choose International Express, air and sea freight.

Q: How do you package products?

A: We use special cartons for packaging. If you have any special requirement, we can customize fumigation-free wooden cases as you required.
