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.
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.
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.
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?
The first time I took this out of the padded box I made for it and poured my sample in, I got wet feet. Hmmm, how could this be? The answer was at the bottom of the storage case where a glass disc sat, perfectly fitting one end of my new glass tube. This jar is probably a nice tool, but rather than mess about I bought your plastic hydrometer jar, not as cool but it works.
Awesome! Finally an economical one made of glass. So clear and glossy, a perfect match to it's counterpart Precision Specific Gravity hydrometer (item #T25). So narrow that you'll use less wort per test. You don't have to worry about it getting scratched and cloudy like the plastic jar, just be careful with this delicate vessel just like anything else made of glass.
