Flash column chromatography is a quick and (usually) easy way to separate complex mixtures of compounds. It is widely applied to organic compounds, natural products, biomacromolecule and other active substances.
WelFlash TM SiO2-Ⅱ flash columns use high quality amorphous sphere silica of narrow particle size distribution as packing materials. This provides high resolution of separation and high-pressure tolerance. The polypropylene tube provides great compatibility with various solvents and corrosion resistance. Each column is strictly tested before delivery to ensure high recovery and reproducibility.
Key Features
- High quality silica with better separation.
- Column size: 4g, 12g, 25g, 40g, 120g, and 220g available
- Particle size: 40-63μm
- Luer-lok TM import and Luer TM export
- Maximum pressure: 14 bar (188psi)
- Reproducible performance from batch to batch
Typical Applications
- Normal phase separation
| Column | Type | Particle Size (um) | Pore Size (Å) | Use |
| WelFlash SiO2-II | Amorphous sphere silica | 40-63 | 60 | Normal phase; separates weak polar compound while using weak polar mobile phase |
