Cold Trap Inner 34/45, GL-18 Connections


Fittings that won’t lock up.

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. You can quickly connect and disconnect the barbs, and we’ve made removing the housing from the cold trap inner easier than ever!
