1) 추출 : 혼합물 속의 두 가지 이상의 물질 중, 한 물질만을 녹이는 특정 용매를 써서 특정 물질만 분리.
2) 거름 : 상이 다른 물질들(보통 액체와 고체)로 이루어진 혼합물을 깔때기와 거름 종이를 이용하여 액체 속의 고체를 분리.
3) 증발 : 혼합물을 가열해 휘발성 용매를 날리고 비 휘발성 물질만

1. 전건 시킨 목재 칩 20g 을 Digester vessel 에 넣고, 백액을 투입
2. Digester 에서 pulping 을 시작하여
15분마다 온도 조절하면서 175도까지 온도를 올려
일반적인 증류만으로는 두 성분을 순수하게 분리해 낼 수가 없다. 즉 이같은 경우 순수 성분을 분리해 내려면 먼저 일반적인 증류에 의해 공비혼합물에 가까운 것을 얻고 그 후에 다른 방법을 취해야 한다.
이 경우 대표적인 방법이 추출증류 (extractive distillation)와 공비증류(azeotropic distillation)이다.
Capsule : take easily
Double action of CLA and HCA
Proved by animal testing
Its CLA is extracted from natural
Its HCA has the result of living-body test
doesn't show the time to take.
Because it is a new product, there can be danger in the long run.
gaseous solvent to form a homogeneous solution of the solute in the solvent.

water-cooled design
It is much more efficient than a simple retort due to its use for liquid cooling
a Liebig condenser can condense a much greater flow of incoming vapour than an air condenser or retort

Uses
A plant cell callus consists of somatic undifferentiated cells from an adult subject plant.
A callus is not necessarily genetically homogeneous because a callus is often made from structural tissue, not individual cells. Nevertheless, callus cells are often considered similar enough for standard scientific analysis to be performed
