Fractional Distillation Unit At a Glance
Fractional distillation, also known as fractionation, is the process of separating liquid mixtures based on differences in boiling points. It is widely employed to purify petroleum, alcohol, chemicals, flavors, fragrances, and more. Compared to traditional distillation, fractional distillation offers enhanced separation for components with closer boiling points.
Labfirst Scientific provides both glass and stainless steel fractional distillation apparatuses with a volume going from 1L to 1000L +, available from lab scale to industrial scale. With over 20 years of expertise in crafting borosilicate glass and stainless steel solutions for the chemical, food, and pharmaceutical sectors, Labfirst Scientific is committed to delivering innovative systems that seamlessly integrate purity, reliability, and superior quality.
