The SFT-130A SFE is an advanced supercritical fluid extraction system. It combines the easy operation of a bench top SFE with many features typically found only in larger and more costly pilot scale systems. The SFT-130A is well suited for a variety of applications from basic research to process development. This SFE system was developed to investigate the application of supercritical fluid extraction to a wide variety
of analytical and material processing challenges.

In addition to its many industrial uses, the SFT-130A is ideal for colleges and universities. It is an affordable SFE for both teaching and research laboratories. It possesses the features required by researchers who require automation of key processing parameters for unattended operation. Operating
pressure up to 10,000 psi (68.9 MPa) and at temperatures ranging from ambient to 120°C make the SFT-130A suitable for almost any research project.

The SFT-130A is equipped with a 1000ml sample vessel. Optional vessel inserts permit operation at reduced volumes of 100, 250 and 500ml. Given this versatility, the SFT-130A is well-suited for both small, analytical scale applications and for slightly larger ones to extract very low levels of key components
from a material or to process larger quantities of materials than are possible on the traditional analytical scale.

Internal temperature stability, an essential processing parameter, is ensured by the system’s integrated pre-heater. The pre-heater provides the fluid to the main pressure vessel at a consistent temperature. This precise control guarantees consistent results from run to run.

The SFT-130A is supplied with a steady stream of high-pressure liquid CO₂ by an integrated, high performance, pneumatically driven piston pump that rapidly compresses liquid CO₂ drawn from a standard laboratory cylinder and delivers it at the pressures required for SFE (up to 10,000 psi).
The unit operates in a constant pressure mode, maintaining a set pressure as the CO₂ extract flows out of the system, through an automated back pressure regulator (BPR), into the collection assembly.

A PLC monitors and controls all functions of the SFT-130A. This provides for fully automated cycle controls, data logging, safety alarms, history recording, and creating processing recipes. Automation of the BPR provides precise control over the flow rate of the expanding gas. This is essential for obtaining highly reproducible results. Flow rates up to 50 ml/min liquid CO₂ are achieved under typical operating conditions (18mls/minute @ 10,000psi).

Extract collectiExtract from a ¼” outlet tube is collected in a vented sample container. Standard sizes range from 50 ml to 1 liter. Co-solvent addition modules are available for the SFT-130A and can be acquired along with the system or added later. Sample containment bags and baskets are recommended to make changing sample easy.

The SFT-130A SFE Unit can be fitted with an optional CO₂ Recycle Module that is capable of recycling >95% of the CO₂ used in an extraction process and reusing it many times.
