stonylab Glass Vacuum Cold Trap Bubbler with 10mm Serrated Hose, 225 mm Length Below The 24/40 Joint

All great!

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!

Good

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.

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

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.

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

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!

Emballage soigné, produit conforme.

Ottima e a buon prezzo, fa il suo dovere molto bene

Top quality products at the home chemist's prices couldn't ask for more. Not to mention pretty much everything you might need and some you won't. All in all very happy thankyou.

Die Apparatur funktioniert, der Schliff ist recht präzise. Wirkt insgesamt sehr robust. Und als einziges Gerät, das ich von stony lab gakauft habe, war es ordentlich mit einer Kulissenverpackung eingepackt. :)

This is a well-made piece of glassware. The description has the joint being larger than the real thing. It's not a big deal so I didn't exchange it. The trap is an excellent value and is carefully produced.
