SFE Extraction Systems - extraction on laboratory scale

analytical SFE/SCF extraction system

Extraction with supercritical Carbon Dioxide CO2!

These robust SFE Extraction Systems (supercritical fluid 
extraction) now at the leading edge of “green equipment 
technology” were designed to cope with growing daily 
requirements of research laboratories. Equipped with a 
multitude of flexible functions, they are very simple to 
operate. The systems are fast and productive, saving you, 
the user, time and costs.

The advantages at a glance:
1. residue-free, dry products, concentrates and substances
2. mild treatment of temperature-sensitive samples
3. selective separation of substances by variation of temperature and pressure
4. aroma-preserving extraction of natural materials
5. simple recovery of the extraction medium 



For the analytical SFE, the extraction on laboratory scale, there are 3 systems:

1. Spe-ed SFE-2:
2 extraction vessels in parallel operation, ranging in volume: 0,5 ml to 950 ml

2. Spe-ed SFE-4
4 extraction vessels in parallel operation, ranging in volume: 0,5 ml to 950 ml

3. Spe-ed SFE-15000:  
for extraction under high pressure (bis 1.000 bar)

SFE - Supercritical Fluid Extraction:

Above a defined pressure (74 bar) and at a certain temperature (31°C) CO2 is transformed into a supercritical state, i.e. it is neither a gas, nor a liquid. However, it has the advantages of both states, best permeability and solubility.

Why CO2? The advantages at a glance:

• best permeability
• low viscosity
• highly diffusible
• high dissolving power
• recyclable
• mild extraction method
• alternative to organic, partly toxic solvents
• non corrosive
• save and environmentally friendly
• no residues
• easy available and inexpensive

Range of uses

Range of uses

The first wide commercial application of supercritical fluids was the decaffeination of coffee. Today you can find supercritical fluids, which are used in numerous SFE applications:

    * extraction of natural products and aromas. Extraction from food, fats and 

    * treatment of biopolymers

    * sample preparation, f.i. for GC/MS analytics

    * cleaning of electronic components, molded metal parts (MIM) and 
       medical implants

    * drying of aerogels and archaeological artifacts

    * dying and impregnation

    * coatings

    * nanoparticles
