We have finally found a glass hydometer jar for little more than the price of a plastic jar. For the purist, this all-glass hydrometer jar holds 200 ml, and stands 12" tall, with a 3.25" wide glass base for stability. The outer diameter of the glass testing tube is 1 1/8", and the inner diameter of the testing tube is 15/16" of an inch.
One inch in diameter, this jar will fit all the hydrometers we sell (except item T09) and requires less sample liquid than other jars. Pictured T07 hydrometer not included. See the more info button below for a close up photo.
Note: This does not fit our item T09 Precision Bottling Hydrometer which is too long for this jar.
This close up illustrates the clarity of this glass hydrometer jar.
You can be the first to ask a questions.
Superior Clarity
The clarity of the readings through the glass is night and day compared with plastic (especially if you use readers). When you see your product in this glass, it will bring a tear to your eye. It's not much more than plastic for the viewing upgrade.

Great hydro jar
This hydro jar is awesome - wish I would have bought it years ago! I hesitated because it was glass but it seems fairly sturdy. The nicest thing about this is it's fairly narrow and you need a much smaller amount of beer than the plastic jars.
Overall I like it, with reservations
The new T09 hydrometer is longer than the older models, causing it to bottom out before reaching 1.000 My opinion is a Final Gravity hydrometer and jar should be able to read a bit below 1.000 Why? Well, it's nice to be able to calibrate using distilled water and if it bottoms out, you're SOL without another hydrometer jar. Also, I'm getting too much attenuation. I don't know why but it would be nice to know how much without resorting to other tools. That said, I really like it when it works. The close fit dampens movement and increases accuracy. With care. So it should be taller. I'll buy a taller one if they get one.
It is too small
The diameter is too small, and it isn't tall enough. When taking an original gravity reading, you are almost certainly going to get trub and sediments. Those particles certainly have a different specific gravity than the wort. How do we know that the hydrometer isn't being jived by a blanket of crud at the bottom?
