This space-saving, elliptical shaped, bump trap is used in rotary evaporators between the steam tube and the evaporator flask.

Prevents fluid from being drawn into the condenser. The unique elliptical shape allows for the same effect as standard traps, but with less space between the flask and evaporator tube. This allows for use of larger flasks in the rotary evaporator bath. Reinforced outer [ST] joint at top, inner [ST] joint at bottom. Fabricated from borosilicate glass.
