- Top-grade borosilicate glass
- New, threaded GL-18 connections for:
- improved vacuum flow with 3/8″ tubing and connections
- increased down-stem diameter (10mm), to avoid in-line freezing of compounds
- reduced chance of breaking the intake and exit ports, thanks to removable connections
- quickly connecting vacuum sources and systems
- Fits into Across International T40 & T80 cold traps – direct replacement upgrade for OEM traps
- Vertical hose connections – reduce hose clutter and stress on cold traps and improve flow
34/45 joint & fittings that won’t stick.
If you’re tired of breaking cold trap barbs or having your tubing get stuck on barbed-glass fittings, you’re not alone.
We were too – That’s why we replaced those fittings with GL-18s.
Now you can quickly connect and disconnect the barbs, and we’ve made removing the housing from the cold trap bottom easier than ever!
