When scientists need to remove different substances from a mixture, they frequently use a technique called wiped film short path distillation. So it is a little cumbersome sounding but it is actually rather straightforward.
The wiped film short path distillation is a process of separation, where heat is used to transform (evaporate) a compound (or mixture) and strip the volatiles away, to change the compound from liquid to gas form based on differences in boiling points. In this process a mixture is heated in a flask and passed up a high pipe. As the mixture is swept up the tube, a revolving wiper fans it out into a thin coating. That way, the various components of the cocktail can transition to gaseous form (and back into liquid) at different locations within the tube. This helps to separate them.
Why Wipe Film Short Path Distillation Separates Compounds So Effectively One of the most common types of short path distillation setups is known as the wiped film distillation system. Because the mixture is spread thinly, there will be more of it directly heated. This serves to elute the substances more quickly and more accurately. This method is also applicable to substances that do not respond well to extremely high heat as it employs lower temperatures and pressures than some other methods.
YHCHEM wiped film short path distillation is ideal for the separation of very minuscule compounds with very little compound waste due to high-evaporation performance of short path distillation. The process allows not only differentiation of different elements, but also weeding out of undesired matter which leads to a cleaner end product. This is especially true for both medicine and essential oils, which we usually need to be as pure as possible.
In comparing wiped film short path distillation with other methods, we must consider their effectiveness, the purity of the results and what the yield is. Old-school processes like fractional distillation may be great for some purposes, but they might not be as pure or precise. Wiped film short path distillation excels in these aspects, which is why its many of our clients in these industries choose this method for their solvent based operations.
YHCHEM short path distillation technology is designed to cause the least amount of harm to the substance and also increase the efficiency of separation. The design of the apparatus assists in a better heat and vapor flow, resulting in faster distillation and better outcome. With that technology, scientists will also be able to do their work faster, and more efficiently.
