How does it work?
The LBV2 works by condensing the intake supply of CO2 gas into a heavy dense cold liquid which fills the process vessel. With temperature control and back pressure regulation, material in the process vessel is pushed through media of your choosing and two in-line filters (various micron sizes available) achieve a wide range of capabilities in isolating and filtering specific components. The filtered material accumulates in the collection vessel as the CO2 passes back into a gas leaving the heavy botanical mass at the bottom to be collected. The amount of CO2 that can be condensed per second is a function of the pressure and temperature of the system. As the temperature of the system increases, the amount of energy needed to evaporate and condense carbon dioxide decreases.
Why Co2?
CO2 is emerging as a spotlight solvent in the extraction of essential oils, spanning multiple industrial fields from medicine to food, beverage, perfumery, and recreational applications. Liquid carbon dioxide is a good solvent for many lipophilic organic compounds like alkaloids and CO2 is not recognized as harmful or toxic and is generally recognized as safe (GRAS). With our liquid CO2 technology anyone can safely produce oils with little to no post processing needed.
This is ideal for use as a botanical oil extractor for several reasons:
• The density remains relatively high, up to the density of liquid, which is ideal for carrying essential oils
• The viscosity remains relatively low, and cannot reach liquid levels of viscosity. This is ideal for moving oils through the medium
• The high pressures necessary for reaching a supercritical state ensure that the oils are efficiently pressed out of the botanical sample

Flash Chromatography Capability:
Due to the nature of CO2 in a supercritical phase being both at once a liquid and a gas, SFC chromatography has the combined benefits of a liquid to dissolve the medium matrix and also an inert gas to push material through filters and media. CO2 alone is a mobile phase that allows separations to occur at lower temperatures, ideal for botanical properties such as terpenes that are volatile with hotter temperatures. There is a wide choice of stationary and mobile phases, chiral and achiral separations, and gradient capabilities across widest polarity range. Additionally, there is a major reduction in the hazardous solvent used if any is needed for your application, and cost savings on solvents and time. From an operating standpoint, SFC is as simple and robust as HPLC but fraction collection is more suitable because the primary mobile phase evaporates leaving only the analyte and a small volume of polar co-solvent.
