1. How does fractional distillation work?

The unit works by heating the mixture to vaporize the components. As the vapor rises through the fractionating column, it gradually cools. Components with higher boiling points condense first and are collected lower in the column, while lighter components condense at the top.

2. What’s the difference between fractional and simple distillation?

Fractional distillation is used for mixtures with close boiling points and requires a fractionating column for better separation. Simple distillation is suitable for separating components with large differences in boiling points and does not require a complex column

3. Is it possible to upgrade an existing unit?

Yes, we can custom the fractional distillation unit based on your needs.

4. How long is the warranty?

The warranty is one year, but the support is lifetime.
