Dry Aerogels without Cracks
Use supercritical fluids and eliminate the capillary stress that causes cracks and yield loss in the aerogel drying process.
No need to tolerate low-yield results as with freeze drying.
The Spe-ed SFE Sirocco is a supercritical fluid system specially designed for aerogel drying.
Automated depressurization
- Touchscreen control of all parameters
- Set your rate of depressurization
- Assured quantitative reproducibility
- Set longer depressurization times (hours, days) if needed, to ensure drying for even the most fragile aerogels
- Set the rate and walk away
Variable size vessels
- accommodates numerous shapes and sizes or powders
- Special “Submersion Holder” to ensure no exposure to destructive 2-phase conditions
No “drift back”
Special heating to overcome Joule Thompson cooling during depressurization preventing “drift back” into destructive 2-phase conditions
- Temperatures to 150°C
- Pressure up to 1,600psi (110 BAR)
- CO2 pump: up to 50mL/min flow rate
- Optional liquid pump
