3.9 / 5.014 ReviewsGrumpyThis product is OK. Not as good as the one it is replacing, but the price was right and it will work just like any other one that I would have purchased somewhere else had it been a better price!! Yes, I shop around and buy where the price is reasonable for the item I need. And no, I don't need anyone from your company to contact me in reference to my review.June 25, 2018Purchased
4 months agoGreat addition to my tool set.Works great, I like the base it is sturdy and keeps the jar upright and stable, other plastic ones seemed to topple easily.June 21, 2018Purchased

1 year agoGlass hydrometer test jar review.You need to have two of these because one of them will break while you are using it. They're made of really thin glass. If one tips over, it's done. There also is no available glass alternative. I'd gladly pay 3 times the price for a Pyrex borosilicate glass one - but the available ones (I've looked everywhere) are just a little too short for the hydrometers that you need to test hi test alcohol. Plastic isn't an option, either. So I order these ones, keep a spare, and replace them when the paper-thin glass meets anything hard. I've had one of these arrive from Midwest broken, but that was a while ago. In any event, this works, but it isn't the best solution....July 29, 2016Not able to useitem was broke in the box. Was not able to useJanuary 2, 2016Nice Test JarThis is a nice test jar. It is made of thick glass and doesn't seem fragile to me, like some reviewers have said. I am sure it will break if dropped on a hard surface, but if you use reasonable care, this jar should last a long time. Do NOT trust the plastic holder though! If you tip the jar upside down, holding only the base, it is likely to fall out and might break. I put a small circle of Velcro on the bottom of the jar and the base to hold it securely in place. This also lets you align the jar perfectly vertical for easy reading.January 16, 2014Glass is GreatGlass is so much better than plastic. You need to be very careful when handling it though.March 5, 2013Great with some modifications!I have broken 2 of these........... Once being tipped over and once by dropping the Hydrometer and breaking out the bottom.. I superglued the green plastic holder to a plastic CD case which gives it much more stability and I stuffed a piece of Stainless Steel Scrub Sponge down in very bottom of Jar, thus creating nice 2 Inch 'Pillow ' in case you drop the Hydrometer too hard in the Jar.... and so far it has worked very well for me..._x000D__x000D_I Would like to see a heat-resistant borosilicate glass Jar offered as an upgrade option . This of course would be more expensive but much more durable.January 12, 2013its greatI just broke mine ordering a new one maybe two. it works great although it will break but i had mine for over a year i had 3 plastic ones and they were the worst things i ever purchased get the glass maybe order 2 i like to have 2 of every glass thing i buyNovember 4, 2012Would not recommendWhen I went to use it I found that it was cracked.Not sure if I broke it or not.Take care when putting the hydrometer in it. If I purchase another one I think the plastic model that screws off the base would be a better choice.October 11, 2012

Browse 2 questions Browse 2 questions and 2 answerswhat temperature can this test jar withstand?BEST ANSWER: This test jar is only recommended to use with room temperature liquids. Glass can withstand very high temperature but this glass has very poor tolerance for thermal stress, so as you heat and cool it, it will not last very long due to the stresses involved in heating and cooling. The question is actually what PSI of stress can it handle. Very little, hence why you should only use it at room temperature. Borosilicate glass has a higher tolerance but is much more expensive.How many oz does this hold?BEST ANSWER: Hello Dan,
Thank you for choosing Midwest Supplies! That test jar will hold 8.84 US fluid oz. I hope that this helps, have a wonderful day!
