HelixTM Process Development Unit
The HelixTM 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:
- 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

|Helix for Aerogel Drying...
What is Aerogel Drying?
Aerogels are highly porous materials with large internal surface area and large pore volumes. Their densities are as low as 3 kg/m3 and have porosities as high as 99.9%. This makes them excellent thermal insulators. Immersed in a solvent, usually ethanol, formation of this highly porous structure is by sol gel chemistry.
Removing the aerogels from the solvent bath for common use is fraught with problems. Because the structure is so fine, normal drying at atmosphere collapses the network into dust. This is from the normal capillary pressure at the liquid/vapor interface on the inside of the pore.
