Helix^TM Process Development Unit

Technical Overview

The Helix^TM is a laboratory supercritical fluid process development unit specially engineered by Applied Separations for maximum flexibility. The modular Helix is optimized, so the system can easily be modified for changing process development needs.

The system features numerous standalone or add-on modules. These can be purchased all at once or separately and added to the existing system. There will be no need to ever buy another SCF system. If your development needs move into other directions, just purchase the appropriate add-ons that can be seamlessly integrated into your system.

Major modules include, with more being engineered:

• Extraction
• Cyclonic separator
• CO₂ pump
• CO₂ recycle
• Modifier pump

Modules can be specially configured to investigate specific supercritical operations such as:

• Nano size particle generation
• Fragrance extraction
• Essential oil extraction
• Cleaning of IC wafers, electronic components and machine parts
• Textile dyeing
• Aerogel drying
• Pressurized (accelerated) solvent extraction
• Subcritical water extraction
• Using other gases

The major system features:

• temperatures to 250°C
• pressure to 10,000 psi (680 BAR)
• pumps 400 mL/min. (or optional upgrade to 800 mL/min.)
• 1000 mL, 500 mL, 300 mL, 100 mL extraction vessel assemblies (to 10,000 psi/680 BAR)
• 1000 mL, 500 mL, 300 mL, 100 mL cyclonic separator vessel assemblies (to 10,000 psi/680 BAR)
• independent temperature and pressure control of extraction vessel and separator vessel
• Stirrer addition capability (optional stirrer assembly)
• 12" x 22" footprint base unit
