Closed-loop Extraction

Although the relatively dangerous production of cannabis extracts using solvents in an open space thrives nowadays, it may comfort you that most legal manufacturers of concentrates have turned to the so-called closed-loop extraction systems.

This system has been commonplace in scientific labs of various industries which process essential oils when producing perfumes, cosmetics and food additives. Extraction using the closed-loop system is an obvious choice in those fields where compounds and essential oils play a vital role. These industries have implemented meticulously-prepared regulations and standards which ensure that all labs producing these extracts are safe in accordance with tried and tested procedures of the given industry.


A new norm

This practice is becoming a norm in the production of cannabis extracts as well. Today, closed loop extraction presents a safer (and much more rational) method of producing extracts. It offers an alternative to more dangerous methods that carry risks of explosions, as well as leaving harmful residua in the final product that is ready for consumption.

Companies such as BHOgart in California or Colorado-based Terpp Extractors have become pioneers of the closed-loop extraction technology, producing new standards of quality.

The greatest plus of closed-loop extraction is the possibility of working with flammable and combustible substances in a device that lacks opening through which solvents could leak or percolate. This is important especially when working with liquids that are under pressure and transform into gas when the pressure is lacking.

Closed-loops systems provide extraction specialists with two important advantages: first, they may use chemical solvents repeatedly, which means less waste and more money saved; and second, they significantly reduce the risk of explosion, as the system is very well sealed.
