Brief introduction to molecular distillation
Molecular distillation is a form of continuous distillation performed under high vacuum. Unlike traditional distillation, which relies on differences in boiling points, molecular distillation utilizes differences in molecular weight. The greater the difference in molecular weight, the more distinct the molecular movement behaviors, resulting in a purer product.
Structure
This is a pilot-scale molecular distillation device, equipped with one 0.1 m² short-path distillation unit. It comprises a condenser, a cold trap, a heat-conducting oil heating unit, a high-vacuum pump, and an electrical control system.
Advantages
Key Benefits of 0.1 m² Distillation Equipment
Low-temperature operation with high efficiency
Operates under vacuum (≤10 Pa), maintaining temperatures far below the boiling point of materials to protect heat-sensitive components.
01
Rapid heating (in seconds)
Materials reside inside for only a few seconds, reducing the risk of thermal damage by over 80%.
02
High-purity products (over 90%)
Effectively separates light and heavy fractions by leveraging differences in molecular movement behaviors.
03
Modular design for easy expansion
Multiple units can be connected in series; available in glass or stainless steel configurations.
04
Compact size (only 0.5 m² footprint)
Integrates vacuum, heating, and cooling systems; features simple one-button operation.

Why Choose us?
Why Use Our 0.1 m² Molecular Distillation System?
Solves traditional distillation challenges
Operates under ultra-high vacuum (≤10 Pa), lowering boiling points by more than 200°C. Ideal for heat-sensitive, high-boiling, or easily oxidizable materials.
Compact yet industrial-grade performance
With an evaporation area of 0.1 m², it is suitable for laboratory testing and small-batch production, handling 50–500 mL per batch. Perfect for purifying high-value products such as CBD oil, pharmaceutical ingredients, and nanomaterials.
Model of molecular distillation device
Note:
1) Different raw materials, different processing capacity, e.g. CBD will be much lower than normal substances;
2) Our SPD is made of stainless steel, but SPD with glass material is available too.
