StonyLab Borosilicate Glass Liebig Condenser with 24/40 Joint 200 mm Jacket Length Lab Glass Condenser

Great quality and fast shipping. Perfect item

I haven't used it yet, just got it today but looks great! I was a bit worried with the reviews but Im happy seeing it😊 I distill my own nitric acid for refining I'm sure it will do fine. I'll update if something changes ...

The glass is nice and thick. The water fittings are nice and solid. 24/40 joints mated up well to other glass. I ran with a pretty high temperature difference and it worked with no issues. It does indeed condense things!

This I originally bought because of the price thinking that it was going to be thin-walled... however that was not the case. At least not with the ones I'm comparing it with ( the real cheap ones on eBay Etc). My only complaint is that the nipples to connect the water line are not both pointing down as pictured but come straight off.I will be looking for these guys for my next purchase.

Product works fine and as you would expect. Couple of issues worth noting, that are not persay a problem with the product. This companies glassware will not work with the 24/40 plastic keck clips you see sold on Amazon. I have tried multiple vendors and they all break almost instantly because the lip of the joint is too thick. So find metal keck clips that have some flex otherwise you will have to force them on pretty hard and they will break and shoot across the room. The only other design change I'd make is if they would put the inlet and outlet port on the same side, as it makes for a cleaner setup without tubing going in all sorts of directions. But besides for these minor gripes, it works perfectly as you would expect. Put it thru a couple run away reactions (not intentionally!) that had some decent vapor pressure buildup without breaking (unlike the pressure addition funnel that did break and covered me in extremely lethal fumes and solvents that I fortunately got away with just a burnt arm).

Great glass will buy again

As described!

The price is good and it arrived in a reasonable timeframe, however the outer joint is abnormally large and none of my clips (multiple brands and materials) fit it well. I will probably just wire it to the still head, or print some custom clips. Otherwise, I have not noticed any major defects and it has performed well.
