Molecular distillation, also known as wiped film distillation, is a cutting-edge thermal separation process that stands out for its gentle treatment of heat-sensitive materials. It is widely recognized as the most delicate form of distillation, causing minimal thermal degradation to the product. This technique excels in separating, purifying, and concentrating natural products and complex and thermally sensitive molecules.
Molecular distillation operates on the principles of short-path vacuum distillation, characterized by an extremely low vacuum pressure of 0.01 torr or below. A molecular still is employed to perform this precise process. During molecular distillation, the distillate liquid is exposed to high temperatures within a high vacuum environment (around 10−4 mmHg) in the distillation column. The evaporator and condenser are positioned in close proximity, with a minimal distance of approximately 2 cm. This setup ensures short-term exposure of the liquid to high temperatures and facilitates efficient separation. In molecular distillation, fluids operate under the free molecular flow regime, where the mean free path of molecules is comparable to the size of the equipment.
Unlike conventional distillation methods, molecular distillation does not rely on pressure for evaporation. Instead, it capitalizes on the line of sight motion of molecules. To achieve this, a short path is created between a hot surface (covered with a film of feed) and a cold surface. This configuration allows for direct vapor flow without the need for a continuous gas phase, resulting in optimal separation while minimizing thermal decomposition and loss of valuable components.

Glass Molecular Distillation Unit
In glass molecular distillation, a thin film of the liquid mixture is created on the inner surface of a heated glass evaporation flask. The flask is typically designed with a long, cylindrical shape to provide a large surface area for evaporation. The flask is connected to a condenser, which is maintained at a lower temperature to facilitate condensation of the vapor.
The process begins by creating a vacuum in the system, lowering the boiling points of the substances being distilled. The heat applied to the flask causes the compounds with lower boiling points to evaporate and rise as vapor. As the vapor travels upward, it encounters the cooler condenser, where it condenses back into a liquid state. The condensed liquid is collected separately from the residue, which remains in the flask.
The use of glass equipment in molecular distillation offers several advantages. Glass is chemically inert, allowing for the distillation of a wide range of substances without contamination. It also provides excellent visibility, enabling operators to monitor the process and ensure efficient separation. Additionally, glass is resistant to high temperatures and vacuum conditions, making it suitable for the harsh operating conditions of molecular distillation.
Glass molecular distillation is commonly employed in various industries, including pharmaceuticals, essential oil extraction, food processing, and chemical research.

The process begins by creating a vacuum in the system, which lowers the boiling points of the substances being distilled. The heat applied to the stainless steel flask causes the compounds with lower boiling points to evaporate and rise as vapor. As the vapor travels upward, it encounters the cooler condenser, where it condenses back into a liquid state. The condensed liquid is collected separately from the residue, which remains in the flask.
Stainless steel is commonly chosen as the material for molecular distillation equipment due to its excellent mechanical strength, durability, and resistance to corrosion. It can withstand high temperatures and vacuum conditions, making it suitable for the rigorous operating environment of molecular distillation.

Multi-stage Wiped Film Distillation
Multi-stage wiped film distillation is a variation of the wiped film distillation technique that involves multiple stages of distillation to achieve further purification and separation. This approach allows for enhanced refinement of substances with high boiling points, low volatility, or complex mixtures. It can be designed as a dual-stage wiped film distillation or even a triple-stage wiped film distillation, depending on the specific requirements of the process.
In a dual-stage wiped film distillation setup, the process includes two consecutive stages of distillation. The first stage operates similarly to a standard wiped film distillation, where a thin film of the liquid mixture is formed on the heated surface, and the volatile components vaporize and rise upward. The vapor encounters a cooler condenser where it condenses and is collected separately.
However, instead of stopping the process at this point, the condensate from the first stage is redirected and introduced into a second wiped film distillation stage. This second stage provides further separation and purification of the remaining components, resulting in a higher level of refinement.
Similarly, a triple-stage wiped film distillation involves three consecutive stages of distillation. The process follows the same principles as the dual-stage setup, with the addition of a third stage for even greater purification and separation.
The advantage of multi-stage wiped film distillation is the ability to achieve higher levels of purity and separation compared to a single-stage process. Each additional stage allows for a more refined separation, eliminating impurities and obtaining a higher concentration of the desired compounds.
Customized services are often available for multi-stage wiped film distillation to cater to specific process requirements. This can include customized equipment design, such as the arrangement of the evaporators, condensers, and feed systems, to ensure optimal performance and efficiency for the desired purification objectives.
Multi-stage wiped film distillation finds applications in various industries, including pharmaceuticals, petrochemicals, flavors and fragrances, and cannabis extraction, where high-purity products are required. The flexibility of this approach allows for tailoring the process to specific needs, enabling efficient and precise separation and purification of complex mixtures.
Hybrid Molecular Distillation
Hybrid molecular distillation is a specialized distillation technique that combines the advantages of both glass and stainless steel materials. This hybrid approach aims to optimize the separation and purification of substances with high boiling points, low volatility, or thermal sensitivity, while leveraging the unique properties of both materials.
Glass is known for its excellent visibility, chemical inertness, and resistance to thermal shock. It allows for easy monitoring of the distillation process, ensuring efficient separation and preventing contamination. Glass equipment is particularly suitable for applications where purity and visibility are critical, such as in the pharmaceutical and food industries.
On the other hand, stainless steel offers exceptional mechanical strength, durability, and resistance to corrosion. It can withstand high temperatures and vacuum conditions, making it ideal for the harsh operating environment of molecular distillation. Stainless steel is often chosen for its robustness and ability to handle rigorous processing conditions, making it suitable for industrial-scale operations.
In a hybrid molecular distillation system, the equipment is designed with a combination of glass and stainless steel components. For example, the main evaporation flask and condenser may be made of glass to take advantage of its transparency and chemical inertness. This allows for easy visualization and monitoring of the thin film formation during distillation.
At the same time, other parts of the system, such as the heating elements, vacuum connections, and support structures, can be made of stainless steel. This ensures mechanical strength, durability, and resistance to corrosion in critical areas of the distillation apparatus.
By combining the advantages of glass and stainless steel, hybrid molecular distillation systems aim to provide the benefits of both materials. The transparency of glass allows for visual inspection, while stainless steel provides robustness and reliability in areas that require mechanical strength and resistance to corrosion.
This hybrid approach finds applications in various industries where the purification and separation of high-value compounds are required, such as in the pharmaceutical, petrochemical, and food processing sectors. It offers improved efficiency, product quality, and flexibility, making it a valuable technique for demanding distillation processes.
