11. Core | MBPR
Whether it be a cyclone separator or a cold trap controlling the pressure inside these vessels can aid in collection or in the case of multi cyclone systems result in selective fraction of the extraction feed. By modifying the pressure and temperature in each separator the density can be accurately control to favour the precipitation of some components over other. The manual back pressure regulators facilitate the control of the pressure in each of the separators.
10. Core | Cold Trap
While its important to expand the CO2 into its gas phase in-order for the extracted components to precipitate from the CO2 feed into one of the cyclone separators, the more volatile components can vaporise and escape with the CO2. The addition of a cold trap after the last cyclone can aidsin trapping the more volatile components obtinained from example terpenes terpenoids.
06. Core | Extraction
Ultilising a static sprung seal we offer tool-less threaded pressure vessel, designed to withstand 1000’s cycles at 689 bar (10,000 psi). We offer a variety or volumes to meet a number of production rates, with our vessels meeting a variety of regional regulations (ASME and PED). this allows us to offer our systems all round the world.

09. Core | Cyclones
Offering both double end and single ended cyclone designs using either standard PTFE o-rings or sprung seals our systems can accommodate either multiple cyclones for either single pot collection or multi pot fractionation.
05. Core | Pre-Heater
The pre-heater is located just after the pump to control the temperature of the CO2 reaching the extractor. It ensures the CO2 entering the extraction vessel is already at the extraction temperature ensuring a controlled extraction process.
02. Core | Flow Meter
Addition of a flow meter improves delivery accuracy by adjusting the flow to compensate for changes in the CO2 feed density. Although we control the incoming temperature of the CO2 a drop in pressure from the CO2 bottle as we consume the CO2, can result in a density shift causing the pump to under deliver the CO2 to the process. The flow meter also offers additional process data to be collected in the system, such as total CO2 used.
02. Core | Co-Solvent Pump
The use of co-solvent pumps have a number of benefits when incorporated into a system. They allow the introduction of solvent to modify the CO2 polarity. But they can be used for cleaning and the introduction of solutes in the SAS process. The co-solvent pumps like our CO2 pumps have been designed from the ground up. In fact they can be used for both operations with the addition or removal of our cooling cartridges.
01. Core | Condenser
Although we use a liquid CO2 feed in our extraction systems, its important that the incoming CO2 remains liquid. The condenser acts to maintain the incoming temperature of the CO2 ensuring it remains a liquid during the pumping phase. Additional condensers can be added with higher flow rate pumps or the addition of a recycling unit.
03. Core | C02 Pump
Built from the ground up using our extensive knowledge of CO2 processing the Core CO2 pumps are designed for high demand environments such as research and production. Our systems can be built to utilise our wide range of pumps allowing us to achieve flow rates between 5g/min upto 1kg/min.
07. Core | ABPR
Utilising a electopneumatic back pressure regulator with our APC control mechanism we are able to automatically regulate the pressure in our extractions, maintaining pressures +/- 1 bar of the setpoint.
08. Core | Vaporiser
Joule-Thomson effect is observed when we go from a high pressure to a low pressure resulting in a drop in temperature. To overcome this, we use a Vaporiser to heat the CO2 exiting the ABPR. The vaporiser also helps to expand the CO2 from its liquid state into a gas in-order to help precipitate the extracted components.

Features
1. Baskets
When performing an extraction, the most convenient accessory is the use of an internal basket. The basket allows you to both load and unload your extraction vessel relatively quickly giving you two major benefits:
i). Quick loading and unloading allows increased turnaround time speeding up the productivity of the system.
ii). Emptying and cleaning the basket can be performed away from the system. This ensures not only that the basket is clean preventing cross contamination, but the system can be running if multiple baskets are in operation.
2. Fractionation
During an extraction, conditions can be adjusted to alter the density of the CO2 to selectively extract specific components. The same tunability is possible on the collection side.
With a system that has multiple collectors with their own back pressure regulators, the conditions in each separator can be adjusted to achieve a specific density. Selectively precipitating different compounds into each of the separators.
3. Subcritical
Supercritical systems the CO2 is above the critical point and in subcritical systems is below the critical point. In practical terms a supercritical system operates above 31C and 74 bar with the temperature being the key factor. In most laboratory scale supercritical systems, heating is done electrically. But if you want to go subcritical, in general you are working at temperatures below 31C. This would be limited when using electrical heating. So most subcritical systems use liquids to heat and cool.
4. Dual Vessel Extraction
Our systems are designed to be modular and upgradeable. This allows our customers to modify the systems to meet their research needs or processing requirements. Dual extraction vessels offer the flexibility to make the system semi continuous by allowing the user to extract from one vessel while preparing another. Or by varying extraction vessel volumes to allow different scale extractions to be performed, making the system both a versatile research tool and a pilot scale production system.
