How to find the right Lab Recovery Flasks AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Lab Recovery Flasks
- Joint match
- Ground joint must match your rotary evaporator vapour duct (24/40 and 29/32 are common) A wrong joint will not seal under vacuum.
- Shape
- Pear-shaped recovery flasks for small residues; round evaporating flasks for bulk solvent The pear shape concentrates residue at the tip for easy recovery.
- Vacuum suitability
- Heavy-wall borosilicate, inspected for star cracks before each use Rotary evaporators run under vacuum and heat.
- Fill
- Charge no more than about half full This limits bumping into the condenser.
Brands that matter
- Chemglass: Wide range of pear-shaped and recovery flasks.
- Ace Glass: Recovery flasks with standard joints.
- Büchi: Flasks matched to Büchi rotary evaporators.
- Heidolph: Flasks matched to Heidolph rotary evaporators.
What to avoid
- Unspecified joint sizes
- Thin-walled flasks used under vacuum
- Overfilling, which causes bumping
