Similar to 89166-576, with the addition of solvent drain holes.

• Traps have a 24/40 top outer joint and a 24/40 lower inner joint
• Unique elliptical shape provides large trap volume
• This allows the use of larger recovery flasks in a rotary evaporator
• Two 4 mm drain holes at the base of the inner tube

Rotary evaporator bump trap is used between the vapor tube and evaporation flask on a rotary evaporator to prevent contents of the flask from being drawn into the condenser in the event of 'bumping'.

Unique elliptical shape provides large trap volume while decreasing the overall length when compared to standard spherical designs.
