Why Polished Vessels Are Essential for Buffer Preparation and Storage
Buffer solutions demand precise pH control and consistent composition for downstream processes. Polished vessels provide:
- Product Protection: Electropolished surfaces prevent contamination and product degradation
- Minimal Particle Generation: Mirror-like finishes reduce risk of particulate contamination
- Superior Cleanability: Smooth surfaces ensure complete removal of residues between batches
- Precise Process Control: Consistent surface properties for reproducible buffer preparation
- Extended Solution Stability: Reduced interaction between vessel surface and buffer components
