stonylab Glass Vacuum Cold Trap Bubbler with 10mm Serrated Hose, 2250mm Length Below The 24/40 Joint

Beautiful glass! Heavy and seems very durable. I ordered the 225ml and it came with a 24/40 joint. Pleasant surprise and no worries there just thought I'd let people know.

I've had some mixed results with stonylab but these have been great. The barbs are just right, have a good hold but aren't impossible to remove tubing from when you want to.I've used them down to 20 Torr absolute pressure and down to -90 °C as vacuum traps. I like that they're wider than most knockouts I've used before, both the body and the stem diameter. Will buy again if I break one!

So far i have used this for multiple different purposes and the trap is of great quality! I have used it as a drying trap, i have used it as a gas trap(filled with sulfuric acid to catch NH3), a bubbler, and a vacuum trap. Love it!

Works well but has a small crack on bottom of tube (not all the way through)

This is exactly what I was looking for. Great Seller.

This arrived fast and I have used it several times already. The only issue I had is the flask sucking the liquid out of the trap . Will buy the other model with the bulb later

Was scared after reading shipping reviews, but item was packed well in foam. Was worried about putting a vacuum on it but it holds up fine.

Used the unit as a condenser for converting a steam back into a liquid. Unit was submerged in iced water and performed flawlessly.
