The Laboratory Glass | Cold Trap LN2 (Large) is a large-format borosilicate glass liquid nitrogen (LN2) cold trap for capturing solvent vapors and light-fraction condensables in the vacuum line between the evaporator and vacuum pump on VTA wiped-film distillation systems. Immersion in liquid nitrogen achieves extremely low trap temperatures (-196°C), effectively capturing even highly volatile compounds before they reach the vacuum pump. An OEM VTA replacement glass component; handle with care and inspect regularly for cracks or chips.
