Supercritical CO₂ Extraction Machines and Equipment
The e-180, our largest supercritical CO₂ extractor.
A supercritical CO₂ extraction machine pumps carbon dioxide above its critical point, 31 °C (88 °F) and 73.8 bar (1,071 psi), through ground plant material in a pressure vessel. In that state the CO₂ dissolves oils, flavors and other non-polar compounds. A separator then drops the pressure, the CO₂ turns back to gas for recycling, and the extract collects with no residual solvent.
extraktLAB designs and builds its CO₂ extraction equipment in the USA, in Osceola, Wisconsin, from the M-2.5 for R&D up to the automated e-180, which processes 384–480 kg (846–1,058 lb) of biomass per day.

How to choose CO₂ extraction equipment
Daily biomass
Start with how many kilograms you need to process per day, then match it to the specifications table. Leave room to add a second unit later.
Floor space and utilities
Check the footprint, ceiling height and electrical supply (208–230 V or 380 V versions), plus clearance around the machine.
Automation
Automated E-series machines cut labor per kilogram. The manual M-120 suits teams that want a simpler machine.
Product
Co-solvents and gradients on the e-140 and e-180 widen what you can extract, from flavors and colors to polyphenols.
CO₂ supply and support
Plan bulk CO₂ with our CO₂ supply equipment, and add commissioning, training, a GMP documentation package or a 12-month maintenance package.
Test your material first
Send us a sample. We run it on our extractors and send back the yield, the settings we used, and whether the process is worth taking further.
Applications
Food and flavor

Frequently asked questions
What is a supercritical CO2 extraction machine?
It is a closed-loop system that raises CO2 above 31 °C (88 °F) and 73.8 bar (1,071 psi), passes it through ground plant material to dissolve oils and other compounds, then drops the pressure in a separator so the extract collects and the CO2 is recycled.
What size are the extraction vessels?
The M-2.5 has one 2.5 L (0.66 gal) extraction vessel, the e-110 has two 5 L (1.32 gal) vessels, the M-120 has one 20 L (5.28 gal) vessel, the e-140 has two 20 L vessels and the e-180 has four 20 L vessels.
How much biomass can a CO2 extractor process per day?
The automated E-series ranges from 48–60 kg (105–132 lb) per day on the e-110 to 384–480 kg (846–1,058 lb) per day on the e-180, at a 60 min cycle and 10% potency. Multiple e-180s reach 2,297 kg (5,064 lb) per day.
What pressure do CO2 extraction machines run at?
The E-series runs from 0 to 345 bar (0–5,000 psi). The M-2.5 R&D extractor covers 55–345 bar (800–5,000 psi).
Where are extraktLAB extractors made?
They are designed and built in the USA by United Science in Osceola, Wisconsin.
What does a CO2 extraction machine cost?
It depends on the model, automation, voltage, certifications and the support package. Email sales@extraktlab.com or call +1 651 600 0036 for a quote sized to your throughput.
Can I test my material before buying?
Yes. Send a sample and we run it on our extractors, then share the yield, the settings used and whether the process is worth taking further. See our feasibility studies.
Is a co-solvent system included as standard?
No. The M-2.5, e-110 and e-140 brochures describe co-solvent hardware as optional. Specify the method and required hardware with the equipment configuration.
Can the M-2.5 support method development for larger systems?
The M-2.5 brochure describes a method-development basis for larger E-series systems. Establish the feed, conditions, collection requirements and analytical endpoint for the intended scale; an R&D method alone is not a production-output guarantee.
Does the equipment footprint include all the space needed for installation?
No. Plan operating access, service clearance, height and ancillary equipment as well as the machine footprint. Confirm the site requirements for the specified configuration.
Is the M-120 available to order?
Yes. The M-120 is available to order. Discuss the configuration and project requirements with us.
