Technical Specifications

SiLen Deep Blue Technical Specifications

The extraction system is configured for the feedstock and target compounds. Items marked "per configuration" depend on the vessel, co-solvent and separation plan; the formal specification governs. Cycle time depends on feedstock and yield targets.

    Adjust system polarity online to match target compounds with different polarities.

  3. Separation Options and Fraction Collection

    Single- or dual-stage separators support staged precipitation and separate collection by target compound.

  4. CO2 Recovery & Purification

    Condensation, purification and buffering reduce consumption and stabilize long extraction runs.

Selection & Preparation

SiLen Selection Questions

Compare chamber sizes, operating ranges and applications →

What extraction vessel volumes are available for SiLen?

Options include a 200 mL integrated unit and 500 mL–3 L plans, including 1 L configurations. Select by packing density, batch throughput, residence time and target compounds. Vessel volume does not directly specify feedstock mass.

Does the SiLen 52 MPa vessel rating mean the system operates at 52 MPa?

No. 52 MPa is the vessel pressure rating. The 200 mL model builds pressure up to 20 MPa; the 1 L model has a pump rated up to 50 MPa. Confirm system operating pressure against the pump, tubing and final engineering plan.

Can SiLen include co-solvent dosing, staged separation and CO2 recovery?

A co-solvent pump, single- or dual-stage separation, and CO2 condensation, purification and recirculation modules can be configured. Selection depends on target compounds, solvents and collection requirements.

Can a supercritical CO2 extractor replace a supercritical dryer?

The process goals differ. Extraction uses CO2 to dissolve and carry target compounds. Drying uses solvent exchange and single-phase removal to reduce capillary-pressure damage. Select equipment for the sample and process goal.
