4mm Thick Lab Glass Extractor / Extraction 38mmOD 14"

Beautifully made. Very thick glass; better than Pyrex. Comes with a nice Neoprene sleeve to prevent cold transfer to your hand when blasting. Lip on bottom adds redundancy to the hose clamps to prevent sliding off. Only wish they sold in in a larger size. This one will fit about 2oz of pulverized herbs.

It says thick. But 4mm is not thick when you're talking glass. Lasted 5-6 runs, then noticed the hair line crack that followed the clamp I used. (once there is a crack, toss it, or risk turning it into a pipebomb) "Hey, maybe you used too much pressure on the clamp." Well obviously, but the point is, the glass was too weak to handle a clamp being hand tightened around it.Look for a few local Headshops, or smoke shops, you will find a THICK tube to use. The shop I go to sells glass tubes that are around 10mm, same price. I tighten the clamp until I feel like the clamp is going to break; several runs later and glass has no problem...That's my two cents; But it is your life.

Does what it is suppose to. Didnt break. I have only used it once tho. So if it breaks in the next couple times I will update my review. But it shipped in a timely manor and works. Holds about 35 gs.

Nice heavy glass.
