High-Capacity Acid Purification
- 4L Throughput Design: Optimized for high-volume laboratories, the DST-4000 allows for the purification of larger batches of acid, significantly reducing the cost per liter of ultra-trace metal grade reagents.
- All-PFA Wetted Parts: Every component in contact with the acid is molded from high-purity PFA, ensuring zero metal contribution and the highest quality distillate.
- Sub-Boiling Technology: High-purity acid is produced via gentle surface evaporation, which avoids aerosol generation and ensures that impurities remain in the feed acid.
Advanced Monitoring & Control
- Digital Temperature Control: Features a separate, user-friendly digital controller that allows for precise temperature settings and features an auto shut-off for safe, overnight operation.
- Graduated Fill Tube: The front-mounted fill tube is graduated to provide a real-time visual indicator of the acid level remaining in the still, simplifying batch management.
- Waterless Distillation: Like all Savillex stills, the DST-4000 requires no cooling water, eliminating the risk of flooding and reducing laboratory utility requirements.
System Components & Applications
- Dual Collection Capacity: The system comes complete with two (2) 2000 mL PFA Lab Bottles (Part #150-01-2000) for high-capacity distillate collection.
- Global Compliance: CSA, Certified, CE certified and RoHS compliant, engineered to meet the safety and environmental standards of modern analytical facilities.
- Universal Solvent Compatibility: Ideal for the purification of HNO3, HCl, and HF for use in semiconductor, geochemistry, and environmental trace metal analysis.
