Description
Freeze drying is not only used for water-based materials. Typical examples include HPLC fractions with organic and inorganic solvents, such as acetonitrile, TFA and other alcohols, or other products with t-butanol, DMSO, etc.
The CHRIST Alpha 3-4 LSCbasic Freeze Dryer model includes: Special system for safe freeze drying of organic samples containing solvents. The condenser temperature of the Alpha 3-4 LSCbasic is –105 °C. The ice capacity is 4 kg.
The specialised system is available in two different package configurations: Flask only configuration or universal flask and shelves configuration.
Meets increased safety requirements for commonly flammable solvents. Increased safety considerations require special system configurations:
- Safe: No sources of ignition, such as commonly used Pirani vacuum sensors
- Durable: High-quality materials for excellent chemical resistance, such as 316L stainless steel for the condenser, manifolds, drying chamber, and solvent-resistant seals
- High-performance: Internal condenser; most solvents are frozen or liquefied in the chamber at -105 °C
- Solvent-resistant hybrid vacuum pump (chemical-resistant membrane plus rotary vane pump)
- Connection for inertisation during loading and defrosting
