Patented Solvent Purifier
Solvent Purification Assembly
Overview
The Vacuum Atmospheres Patented Solvent Purifier System removes moisture from organic solvents more safely than thermal distillation. The system repeatedly circulates solvent through a factory conditioned purification cartridge and a stainless steel reservoir.
Key Advantages
- Designed for 4-liter solvent bottles, minimizing volatile solvent storage
- Reduces waste from impurity accumulation (including peroxides)
- No heat or reactive drying agents required
- Enables precise dispensing of anhydrous solvents on demand
- In-box dispensing options available
Key Benefits
- Removes H2O in ACS grade THF to less than 1 ppm
- Closed-loop circulation provides anhydrous solvent in 6 hours
- Operates safely at 1 psi pressure
- Dries up to 200 liters with one cartridge (ACS grade solvent)
- User-replaceable drying media
- Eliminates need for large external solvent kegs and fireproof storage cabinets
- Modular design fits standard exhaust hoods
- Expandable configuration
- Simple NW40-KF feedthrough filling on each module

Performance Data
The solvent purifier removes moisture to less than 1 ppm (Karl Fischer titration measurements using ACS grade THF without inhibitors).
Purification Time: 6 hours conditioning time; capable of producing over 8 liters of anhydrous solvent daily.
Cartridge Life: Approximately 48 grams of H2O removal (~250+ liters ACS grade solvent at 200 ppm).
