This previously-owned Chemglass rotary evaporator bump trap (modified with two 4mm drain holes at the base of the inner tube to drain solvent back into the evaporation flask), model no. CG-1321-06, has a capacity of 250mL and a lower inner joint size of 24/40.We also carry other brands (e.g., Adams & Chittenden and Synthware), capacities, and top/inner joint sizes. Some bump traps have no drain holes (equal to CG-1320); some inner vapor tubes are sealed to the top of the trap to prevent solvent from entering into the condenser (CG-1322). Some bump traps have tapered sidewalls and four large holes on the upper stem for self-washing (model CG-1319).
Condition: Clean, with cosmetic imperfection (line etched across the bump trap), due to previous use. Sold "as is" without warranty, expressed or implied. Buyer is responsible for determining the suitability of this product for their application.
