Bottom Vapor Tube Traps
Traps are designed for use between flask and rotary evaporator to reduce carry-over from foaming or bumping. No drain holes assure that dry residue does not get re-wetted. The modified joint on the 570260 series features a square bead for better sealing to rotary evaporator equipment. Traps are manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements.
