These are made very well, but as a very amateur chemist, I have come to learn that a 400mm graham condenser is like the heavy artillery of condensers, and I only needed a 200mm straight-through condenser for making dioxane. The 400m graham still works, its just a pain to setup because its so long, and must be mounted vertically. Now I know!

Arrived unbroken. Two minor cosmetic defects in the outer glass jacket, but probably to be expected in such a complex assembly. They don't affect the performance, which is good. Reasonable price.

ive never recieved a broken or damaged glass part from these guys, an ive bought quite a few different lil glass thing in my endeavor to piece meal together different distilling apparatuses. these guys def know what they're doing, in my opinion. it comes packaged nice an safely. i can't see it getting damaged in normal everyday delivery situations. an the glass its self doesn't feel cheap or thin or flimsy at all, it dope an its worth every penny so far. i love watching it fill up with the coolant, i feel like a real scientist lol.

when buying the product I did not know the outer diameter of the water in and water out adapter and bought the wrong tube. leaked all over the place until i added coconut oil to seal it. beginners mistake. Great performance. well priced.

I use this condenser for reduced pressure distillation. I received this is great condition: there were no cracks, scratches, or damages. It functions exactly as I would expect from my past experiences in academia.

I used this condenser to assist in making oil essences. Worked better than the other I had that was twice as long.

I cannot recommend the purchase of any Stonylab’s borosilicate glass condenser. I have had three of them, two 500mm and one 300mm, all of them arrived broken because they are poorly packaged. This has caused me to lose 2019’s Fall medicinal and wild flower essential oil production. To be fair I believe they make decent products, but, one would think with all the effort to produce and market this item they would at least insure it arrives intact by protectively packaging them properly.

Thin nature of inner glass makes it delicate...good chance of arriving broken!

Le seul point faible sont les micro chocs internes quand on le manipule un peu trop fort. Le serpenti est probablement trop proche de la paroie. Mais rien d'alarmant quand on est soigneux avec son matériel. C'est juste plus délicat quand ce n'est pas du pyrex.
