Product Description
When a rotary evaporation bumps, you want the trapped liquid back in the flask quickly instead of sitting in the trap. This vapor tube trap stops splashes from reaching the condenser and drains its contents back into the evaporating flask efficiently.
This listing is for Kimble catalog number 570265-2514: KONTES Vapor Tube Trap, 14/20, Square Bead, 250 mL. The inner vapor tube has two 4 mm drain holes at its base, set 180 degrees apart and 90 degrees from the upper holes, for faster return of trap contents. Units have a 24/40 top joint and 14/20 or 24/40 bottom joints in 100 and 250 mL sizes, with standard or square-bead versions. Glass is low-extractable 33 expansion borosilicate. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
Key Features
- Fast drainage – Two 4 mm base drain holes return trapped liquid to the flask.
- Offset hole pattern – Lower holes sit 90 degrees from the upper holes.
- Square-bead option – Improved joint seal on rotary evaporators.
- Two sizes – 100 mL and 250 mL trap volumes.
- Low-extractable borosilicate – Meets USP Type I and ASTM E438 Type I, Class A.
