A Vigreux Distillation Column (often termed a "Thorn" or "Hammer-Stab" tube). It is a specialized piece of fractional distillation glassware characterized by multiple internal indentations (the "thorns") that significantly increase the surface area for vapor-liquid contact.
Key Performance Features
- Increased Theoretical Plates: The "thorns" allow for multiple cycles of evaporation and condensation within a single column, providing much sharper separation than a simple glass tube.
- Low Hold-up: Unlike packed columns (filled with beads), the Vigreux design has a low liquid hold-up, making it ideal for distilling small quantities of material.
- Airtight Connections: Precision-ground joints ensure compatibility with other components like distilling heads and condensers.
