Chemglass Modified Bump Trap 250 ml 24/40 Joints

The Chemglass CG-1321-06 is a 250 ml modified bump trap designed for use with rotary evaporators. This specific model is engineered with a 24/40 top outer joint and a 24/40 lower inner joint, allowing for seamless integration into standard laboratory setups that utilize these common joint sizes.

A primary feature of the modified design is the addition of two 4mm drain holes located at the base of the inner vapor tube. These holes provide a functional advantage by allowing any solvent or foam that "bumps" into the trap to automatically drain back into the evaporation flask, which prevents sample loss and keeps the condenser clean.

Constructed from high-quality borosilicate glass, this trap offers excellent chemical resistance and durability. It provides an expanded volume of 250 ml, making it particularly effective for managing reactions that have a tendency to foam excessively during the solvent removal process.
