Product Description
A trap that cleans itself during operation means less sample left behind and less scrubbing afterward. This self-washing vapor tube trap uses condensed solvent to continuously rinse its walls during rotary evaporation, returning material to the flask while blocking bump-over.
This listing is for Kimble catalog number 570300-0114: KONTES Self-Washing Top Vapor Tube Trap, 100 mL, 14/20. Tapered sidewalls let condensate wash the trap while avoiding cold spots along the vapor path. Four large holes in the upper stem let vapor flow freely and make cleaning easy, and the larger trap volume helps prevent bumping. Joints are 24/40 on top with 14/20 or 24/40 bottoms and square beads. Glass is low-extractable 33 expansion borosilicate. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
