Customer questions & answers



Just received it. Haven't heated, or dropped, it yet. The interior diameter of the opening is 1 3/8 in, or 34.9 mm, which means a #8 stopper should work.<br><br>No visible bubbles or deformations.

First things first, if you do decide to purchase this to use with a Buchner funnel you are absolutely going to need adapters or cones for your funnel. If you search "buchner funnel adapters" on here you should be able to find them.<br><br>Glass arrived with no visible defects. Have used several times with a glorified aquarium pump and Buchner funnel for distillation and making tinctures. Works without issue, but the mouth of the flask is quite large and Buchner funnels tend to run "thin." To remedy this just buy adapters.
