The LCTR® reactor is an apparatus to manufacture compounds in the chemical industry field, selectively separate and collect the desired substances from a bulk state substance, and produce high-purity substances through a re-crystallization process. LCTR® means an reactor using a Taylor fluid flow developed by our company, which is the first chemical reactor in the world to produce high-purity substances uniformly. The LCTR® reactor is supposed to replace the existing chemical reactors through the production of high-purity substances via a very uniform and powerful mixing effect using a Taylor fluid flow, the reduction of reaction time, the enhancement of productivity via continuous production, the reduction of costs via an increase in yields, and the very simple operating method. Laminar's LCTR® reactor is an apparatus protected by a patent.
