Product Details
✓Application: Expansion trap for distillation or reflux setups where foaming, frothing, or bumping may carry liquid toward the condenser or upper apparatus.
✓Joint Configuration: 29/42 Outer Joint at the top and 14/20 Inner Joint at the bottom; connect only to matching standard-taper joint sizes.
✓Internal Design: An upper-connected glass baffle tube opens inside the bulb, creating an indirect vapor path and space for entrained liquid to disengage and return downward.
✓Capacity: The 250mL bulb provides additional expansion space for larger batches or mixtures with stronger foaming or bumping tendencies.
✓Material & Safety: 3.3 Borosilicate Glass, ASTM E438 Type I, Class A. Inspect for chips or cracks before use, support the assembly with suitable clamps, and never heat or evacuate damaged glassware.
