Design allows for molecular distillation or fractional distillation, plus choice of glass, 316L stainless steel, or Hastelloy. Product Literature Review After vitrifying a sample, LifeCell researchers put it into a strong vacuum until most of the water has diffused out-- a process called molecular distillation drying.
Distillation Distillation is a commonly used method for purifying liquids and separating mixtures of liquids into their individual components. Familiar examples include the distillation of crude fermentation broths into alcoholic spirits such as gin and vodka, and the fractionation of crude oil into useful products such as gasoline and heating oil.

From Langmuir s equation it is clear that it is possible to separate substances of the same vapor pressure but different molecular weights by molecular distillation. An essential feature of molecular distillation is that it is capable of separating substances having the same vapour pressure, but differing in molecular weight. If we examine ...
In this work, important results from simulations are presented, showing the potentiality of the molecular distillation process for recovering vitamin E from vegetal oils. Two types of molecular distillators are considered: falling film and centrifugal. The results emphasize the degree of recovery and factors that influence substantially the ...
Jan 05, 2020 Molecular distillation is a special liquid–liquid separation technology under high vacuum, which is employed as a separation process in the food industry [32,33]. Molecular distillation can divide the EO mixture into two different phases according to the free path of different molecules at low temperature.

Molecular distillation became an important industry during the past fifteen years, and has enabled many thermally sensitive materials to be prepared on a commercial scale, but the development of stills appears now to have reached a resting-point. After a short introduction, the author discusses in turn the various forms of molecular still existing at the present time, …
Molecular distillation. Molecular distillation is a type of short-path vacuum distillation, characterized by an extremely low vacuum pressure, 0.01 torr or below, which is performed using a molecular still. [1] It is a process of separation, purification and concentration of natural products, complex and thermally sensitive molecules for ...
Predict Distillation Tray Efficiency. An empirical technique — the O’Connell correlation — is widely used to estimate the efficiency of cross-flow trays. This article proposes a modification and clarifies the relationship between the empirical and theoretical approaches. Figure 1.
