Graduated cylinders arrived quickly, were packaged well, and in perfect condition. They were exactly as described and included all pictured pieces including three glass eyedroppers and two bottle brushes. The glass cylinders are extremely well made and worked perfectly for my use. I would recommend.

Much better quality then I expected for the price! Good heavy cylinders with cleaning brushes. I use these to make ceramic glazes, so far so good! Clean easily, no scratches even with the abrasive materials. Shipped in a very secure package, even with my terrible mail service they arrived intact (unlike the other glass instrument from another seller that shipped in the same package from amazon which was shattered) The amazon box was smashed on one end but I was pleasantly surprised that none of the cylinders were damaged. I would definitely buy again.

I make essential oil blends and these work wonderful for me. The markings are clear and easy to see. The variety of sizes are perfect when working with various quantities in a blend. They are sturdy and stand solidly without wobble or fear of tipping easily. Even when one was accidentally tipped over onto a tile countertop, it did not crack, chip, or break. The brushes included work great for cleaning even the smallest cylinder.

Nice packaging, thick glass, better than advertised accuracy, includes brushes. That being said, I don't want to suggest that these are the equal of a well recognized brand's "Class A" cylinders costing several (maybe 10?) times as much. I can't make a comparison with a "nice" cylinder, but I would expect that a name brand product would have better QC. The markings on my set are less sharp and crisp on some cylinders than others. This is not glaringly obvious, but it reveals the manufacturing conditions required to meet the very reasonable price point. Aside from that though, I took multiple measurements with each cylinder, checking the mass of distilled water at 20C to 5 significant figures on calibrated equipment and found mine accurate to within about half of the indicated error or better. The precision was even better, suggesting that the markings are well matched to precisely made tubes. My 100mL delivers about 0.45mL+/-0.2mL more than indicated. The 50mL and 10mL give consistently about -0.2mL and -0.1mL respectively. That's pretty good I think. If I needed more accuracy I think I would go by mass instead of volume anyway. One note, these are marked EX (same as TD). These markings mean that the measured amount will be delivered when poured out, not that the cylinder contains the measured amount. The little bit left after pouring is supposed to be take into consideration, which is what you want for this type of cylinder.

I purchased these for a little more precision mixing essential oils blends. After using them, I will be using them for a lot more. They are well packed and include a small and large scrub tool for cleaning (I'm sure there are better quality scrub brushes, but these do get the job done). The glass is thick and held up to an accidental tip-over! These are great for the money and I would buy these again! - I couldn't find a picture of the bigger ones in use, so I included a picture that had the smallest one. I may add more pictures (but, if you want more picture I will post some!).

Top quality lab pieces. Excellent secure packaging, lab quality markings, excellent thickness and complete set. I just use these to measure Syrup but these are experiment , lab grade pieces that will last for years to come. For me they are worth every penny as I won't worry about a simple bump or fall on the counter breaking them. The base is nicely formed to prevent it from creating a fluid bond or static cling. Would be a great set for science experiments at home or simply for the home chemist mixing up concoctions or recipes. Comes with two quality tube cleaners.

Very nice and sturdy! I don't know what the accuracy is like, considering I have nothing to gague that against. These do, however work very well for measuring and mixing e-liquid juice for my vape!

Easy to read and very helpful in measuring my essential oils. Love how they were packed. I keep them in the Styrofoam packaging when not in use so they won't get broken. I love them.

These measuring cylinders are very well made and have a nice and safe storage container. I bought these for use with my Ceracote operation and with these cylinders the Ratio measuring is perfect . I would highly recommend these to anyone requiring an accurate measure of liquid.

Fantastic beaker set that includes cleaning brushes! These are sturdy, high quality measuring beakers provided in a safe and easily reusable styrofoam case that affords great protection against breakage and easy storage for the cylinders when not in use. Great idea to also include the cleaning brushes -- also with a storage location in the foam protective case.
