短程蒸餾的好處
 
幾個世紀(jì)以來，蒸餾一直用于通過高度選擇性的加熱和冷卻來分離液體溶液的成分。多種儀器用于控制溶液中流體隔室的不同熱力學(xué)特性，促進(jìn)混合物通過沸騰、蒸發(fā)和冷凝分離。該方法具有廣泛的應(yīng)用范圍，但通常與增加發(fā)酵飲料的酒精含量和凈化水源以供人類安全食用有關(guān)。

短程蒸餾是一種緊湊的純化方法，非常適合需要最小化儀器占用空間的實驗室應(yīng)用。這種低壓技術(shù)使用多個燒瓶和相對較短的萃取進(jìn)料來分離僅幾厘米的路徑上的冷凝介質(zhì)。傳統(tǒng)的蒸餾方法通常需要更大的設(shè)備來達(dá)到應(yīng)用特定要求所需的純度水平。同時，短程蒸餾可以在更小的工作空間內(nèi)使用多種組分實現(xiàn)高達(dá) 99% 的餾出物純度。
 
這篇博文將更詳細(xì)地探討短路徑蒸餾的工作原理和好處：

短程蒸餾如何工作？

在短程蒸餾裝置中，液體溶液或乳液懸浮在蒸發(fā)燒瓶中，該燒瓶通過短進(jìn)料連接到冷凝器或冷卻裝置。將蒸發(fā)瓶放置在加熱套中，該加熱套逐漸將溶液的溫度升高到預(yù)定的沸點，從而促進(jìn)溶液的不同隔室蒸發(fā)。

真空條件用于將蒸汽通過進(jìn)料吸入冷凝單元，在冷凝單元中，液體溶液的分離的氣相隔室被冷卻并轉(zhuǎn)化回液體。這種餾出物材料根據(jù)其重量被分成不同的燒瓶，使化學(xué)家能夠輕松地從單個樣品中整合多種所需元素。

在大麻油蒸餾的情況下，短程蒸餾代表了一種用于分離大麻素、萜類化合物和調(diào)味化學(xué)品以及有機(jī)和無機(jī)污染物的經(jīng)濟(jì)高效的解決方案。該方法不需要額外的溶劑來​​催化蒸餾過程，并且可以提供高蒸發(fā)速率以提高餾出物的固結(jié)水平，并具有良好的自動化程度。

The Benefits of Short-Path Distillation


Distillation has been used for centuries to separate the components of liquid solutions through highly-selective heating and cooling. Multiple instruments are used to manipulate the differing thermodynamic properties of the fluidic compartments within a solution, encouraging mixtures to separate through boiling, evaporation, and condensation. This methodology has a broad range of applications but is conventionally associated with increasing the alcohol content of fermented beverages and purifying water sources for safe human consumption.
Short-path distillation is a compact purification method that is ideal for laboratory applications where minimal instrumentation footprint is essential. This low-pressure technique uses multiple flasks and comparatively short extraction feeds to separate condensate media across paths of just a few centimeters. Conventional distillation methods often require much larger apparatus to achieve the requisite purity levels for application specific requirements. Short-path distillation meanwhile can achieve distillate purity levels of up to 99% using multiple components in a smaller working space.
 
This blog post will explore the working principles and benefits of short-path distillation in further detail:
How Does Short-Path Distillation Work?
In a short-path distillation setup, a liquid solution or emulsion is suspended in an evaporating flask that is connected via a short feed to a condenser or chilling unit. The evaporating flask is placed in a heating mantle which gradually increases the temperature of the solution to pre-determined boiling points, encouraging distinct compartments of the solution to evaporate.
Vacuum conditions are used to draw vapors through the feed into the condensing unit, where the separated gas phase compartments of the liquid solution are cooled and converted back into liquids. This distillate material is separated into distinct flasks based on their weight, enabling chemists to easily consolidate multiple desirable elements from a single sample.
In the case of cannabis oil distillation, short-path distillation represents a cost-effective solution for separating cannabinoids, terpenoids and flavoring chemicals, and both organic and inorganic contaminants. This method does not require additional solvents to catalyze the distillation process and can provide high evaporation rates for increased levels of distillate consolidation with good degrees of automation.
Short-Path Distillation with Equl
At Equl, we provide a broad range of laboratory instrumentation for numerous application requirements. Our aluminum-housed EMS StirMantle is engineered for contact heating of glassware through variable heating of aqueous solutions via electromagnetic or motor-driven methods. This component can withstand internal operating temperatures of up to 400°C (752°F) and is suitable for short-path distillation of cannabidiol (CBD) and tetrahydrocannabinol (THC).
