3.8 / 5.012 ReviewsGlass is GreatGlass is so much better than plastic. You need to be very careful when handling it though.March 5, 2013Holds up very well, think I need one more I broke it when cleaningJanuary 13, 2017Purchased
1 year agoWorks wellWorks really well for taking AC readings - be careful using this - if you are having a home brew. It is glas and will break if you push it over.March 22, 2012Great test jarIMO be careful with it, but its not that fragile. Works great for what it's intended for. The glass vial fits OK in the stand, I wish it would be a bit tighter, that's my only complaint. It doesn't screw in, just slides. Overall great buy for the price, much better than plastic.July 10, 2012Glass 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, 2016FragileMy own fault ,I bumped it while putting it down an broke the bottom of the glass. VERY fragile. Handle with care. I'm ordering a plastic one this time.May 26, 2012its 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, 2012Great 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, 2013Nice 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, 2014bad constructionI read the other reviews before I bought it and thought - sure it's glass, of course you have to handle with care! No, there is more to the comments. It broke within a week... I think the green plastic base is too light not wide enough, hence the whole thing is very unstable. Also the glass doesn't have any 'bounce' to it like other lab-ware or wine glasses. It breaks even when tipping on a kitchen towel. Look for an alternative.June 23, 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!
