As a first instance, if you choose to buy this to use with a Buchner funnel, you will need to purchase adapters or cones to use it. There should be Buchner funnel adapters available on here if you search "buchner funnel adapters. ". I was surprised to see no noticeable defects in the glass. The hydrometer has been used several times with a glorified aquarium pump and Buchner funnel for distillation and tincture making. It works without issue, but the mouth of the flask is rather wide, so Buchner funnels tend to be a little thin. To fix this, you simply need to.
Almost half of the demarcation lines have already come off (order placed six Even so, the glass is of obvious high quality, as it can withstand the temperatures required. There's nothing wrong with the glass, just the markings are bad. * br>* For the benefit of As a result of JD Tech's proactive efforts, I'm satisfied with the resolution to my issue.
A few little nicks and scratches, but it seems airtight. The vacuum hose is connected to the barbed glass by a tiny crack at the tip of the barbed glass. I think, if not for these few yet very minor problems I would have given it a 5 star rating if not for the less than low price, I would have given it a 2 or 3 star rating.
I received it just now. I have not yet heated or dropped it. One third of an inch, or 34 millimeters, is the interior diameter of the opening. I believe a #8 stopper will work since it is 9 mm in diameter. Neither bubbles nor deformations are visible.
Purchase is not a good decision. Two Filter Flasks were returned for low quality glass because of air bubbles in the glass. Stoney Lab Glass for the 2000ML Filter Flask is of LOW QUALITY. PURCHASE WITH CARE.
This broke after being heated about 3 times and I was not able to find any warranty for it here in my opinion, look for tech grade if you are planning to use it again, this is cheaply made and my opinion is to sell it if a certain seller would replace it.
After the first one I bought broke, the customer service rep sent me another one for no additional charge. The glass is strong and the product itself is great.
An drilled #2 stopper caused the neck to be below the side of the plate. If you are between sizes, go up a size.
