Perfume is expensive. But have you ever wondered what the most expensive fragrance ingredient is, all the way at the high end of the spectrum? You probably didn’t guess whale discharge – but that’s the answer! The material is called ambergris, a hardened...
Aerogels are ultra low density wonder materials, the lightest solids on the earth. They could be the key to unlocking the future – NASA says they could change the way we think about insulation, and has used them extensively for cutting-edge space technology and...
Canisters are fast, easy, clean, and essential for any GMP Extraction facility. They provide even CO2 flow through the material, preventing clogs. Canisters also decrease downtime between cycles and eliminate the need for...
Hightech's Triple Extractor Configuration Provides Maximum Flexibility & Maximizes Throughput The triple extractor configuration is the most flexible configuration in an SCF system. The machine’s flexibility is enhanced by our automation-by-recipe process. It can...

Operator safety is a paramount concern! Lids can be very heavy and difficult to manage. In keeping with firm EU safety standards, Hightech Extracts equips all extractor vessels over 100 Liters with robotic lid handling included.
Pump Flow: The perfect sizing was done after the analysis of a million dozed processes data tag and efficiency evaluation. You can see the result of our efforts in this surface plot. In our systems we found the best combination between Process Pressure, CO2 Flow / Extractor Volume ratio and Efficiency of the process.
The double extractor system gives you a great advantage: semi-continuous extraction. This kind of extraction means that the process never stops. Semi-continuous extraction reduces downtime and bacterial contamination in the system.
The cyclonic separator is different compared to the gravimetric separator — while S1 works by gravity force, S2 works by centrifugal force. The fluid moves very quickly, creating a vortex inside the vessel. The fluid continues to spin and the particles of extract begin to separate moving toward the walls of the separator, sliding to bottom.
The condenser is essential in CO2 recirculation. The condenser is a piece of apparatus or equipment that can be used to condense, or change the physical state of a substance, from its gaseous to its liquid state. We use a double-pipe configuration in small systems (up to 48-liter) and a shell and pipe configuration for industrial systems.
Our extractors don’t use piston pumps or compressors, we use membrane or diaphragm metering pumps only. Although the cost is higher compared to a simple gas booster or piston pump, the advantages are considerable. In fact, diaphragm metering pumps are not affected by supercritical fluid because process fluids are completely separated from the mechanical part of the pump.
While in the simple semi continuous extraction the system is equipped with two extraction vessels, for semi-continuous serial extraction the system is equipped with three extraction vessels. Taking advantage of the typical flowers and leaves extraction kinetic, the intelligent automation of the system will apply a different extraction strategy.
Quick Closing System Quick opening cover design needs only one-eighth of a turn rotation for sealing. Ideal for high-pressure operations requiring repetitive opening/closing. The "Clover Leaf" closure reactors provide maximum ease for quick opening or closing of the...
The gravimetric separator is the first separator (S1). It applies the gravimetric effect to separate the extract in fractions. This separator is heated at a set-point temperature.
Automation is a generic term, and all systems can be described as “automatic” in some way. We believe automation is more than just simple control over pressure, flow and temperature settings. Our Adaptive Automation process is a new hardware/software system that is able to change the extraction cycle in real time as requested by the operator.
The Coriolis flow meter is basically a mass flow meter. It gives you exactly the mass of CO2 is delivered by the membrane pump and is essential for proper feedback and control over the CO2 flow in the circuit.
CO2 isn’t a liquid at normal room temperature and pressure. It is a gas. When temperature and pressure are increased over the critical point, we have supercritical fluid. The CO2 is at the same time a liquid and a gas at every point along the Equilibrium Curve.
The cleaning procedure is an important practice: it has the same importance as the extraction process. Any extraction system needs to be cleaned periodically: this period depends on many factors, including the type, quality and pre-treatment of raw materials, use of a co-solvent, and the number of extractions between cleanings.
Traditional technologies in many cases do not offer a satisfactory solution to a specific problem. Furthermore, there is a continuous search to reduce production costs. Pilot scale studies may show that, despite initial high capital costs, operating costs would be lower and the overall feasibility can be proven at certain scale of operation.
We say that a liquid is in equilibrium with its gas when the same mass is exchanged from the gas to liquid and from liquid to gas. This happens continuously, and this point is strongly dependent on pressure and temperature. Any change in temperature produces a change in the pressure.
Supercritical carbon dioxide isn’t just an efficient solvent for apolar compounds. In fact, if it’s combined with fluid modifiers like water, it becomes a very efficient solvent for medium polar and polar substances (caffeine for coffee decaffeination). The extraction efficiency is better than conventional technologies based on chemical solvents.
The Supercritical CO2 extraction process is “geometrically variable.” A supercritical fluid is any compound at a temperature and pressure above its Critical Point. It can diffuse through solids like a gas, and it can dissolve materials like a liquid. For any pure compound, there is a transition state called “critical” state: for temperatures below the critical temperature (Tc), two phases — liquid and vapor — coexist; for temperatures above Tc, there is only one phase: supercritical fluid.
After the extraction process, the mixture composed of CO2 and solutes leaves the extraction vessel(s) and it is directed to the separation vessels. By varying the pressure, flow and temperature of these vessels, it is possible to induce the selective precipitation of different chemical compounds as a function of their different saturation conditions in the supercritical fluid.
The Artisan 7 provides the extraction artist with a system they can manually control, run various temperatures and pressures and flow rates to personally create their desired results. Like all the HTE Production Series, the robust build, ASME certified components, and safety are all built in.
