Thick Glass Graduated Measuring Cylinder Set 5ml 10ml 50ml 100ml Glass with Two Brushes

Pretty dang good for the price. You can tell it's cheaper glass, there are some abnormalities in it, but it doesn't seem to affect the measurements. Everything looked good. Even the droppers are glass, two of them are very thin but the third is very sturdy. Everything is easy to read. Comes with two cleaning brushes (I assume that's what they're for). One minor cause for concern is it came labeled MADE IN CHINA and when I opened the box all the glass and accessories were covered in a white powder. Nothing like getting science instruments covered in mystery powder. Thought about snorting a line. Not sure what that is, but I assume It's probably just something from the manufacturing process or perhaps to like talcum to keep the glass from rubbing together in shipping. I don't know. Hopefully I didn't just get a face full of research chemicals.Overall, great buy. Would recommend.

I can't see any hint of etch, but the box says "scale clear (which it certainly is) never fade (time alone will tell)" I can't scratch it off, with my finger nails( which I find is usually the case), so,so far, so good! I used my triple beam balance , and subtracting the weight of the glass ,added water to various marks on the scale(water being the same in ml as grams, not so, for other mixtures) the weight corresponds to grams, and hits the ml Mark fairly closely, without spectroscopic test, it seems fairly solid, heavy glass ,wide bottom,making it more difficult to knock over, nice and stable ,I like that! So probably acid proof, the pouring spout is really lovely and seems to work out very easily and carefully,I like that! Just some notes to add to the more positive reviews...

This is a great set of graduated cylinders, the unfortunate thing was that my 100 ml cylinder was cracked at the top. This could have happened anywhere, even in transit so I am not deducting any stars for it. I wrote the seller and I am awaiting feedback from them regarding the exchange process. On that note, it comes with three awesome pipets, two brushes, and four sturdy cylinders. I am well pleased with this set.

The cylinders are great, pretty pleased with them; everything arrived intact, the cylinders are thick and strong, they hold up to rapid temperature shifts that soda lime glass likely wouldn't, they appear to be made of good ~33 borosilicate, and the graduation marks at least as accurate as I need. I've used them nine out of nine days since I received them, with quite a few different organic solvents and strong acids and for measuring chemicals across a reasonably wide temperature range (roughly 290°K to 400°K). Thus far all have held up flawlessly, no etching after holding tech+ grade H2S04 or HCl for long periods, and the graduation marks remain intact. Great deal for so cheap, 20+ years ago I'd be paying several times as much for just one of the 50 or 100ml cylinders, when I could even find stuff like this in town.The fact that I can just buy a brand new büchner funnel of virtually any type for like $10-50, or grahams/liebigs/flasks/stands/so much more, and have them arrive today or tomorrow, is just mindblowing. I guess "they" haven't made home/small lab chemistry involving only licit compounds illegal, yet!The droppers are junk though, particularly the graduated dropper which is completely unusable out of the box. The bulb is so loose it just falls off when you invert it, but the glass itself has a notch that made it compatible with another dropper bulb I had around. I can't pull a whole cc now but oh well, perhaps at some point I'll seal the original bulb back on somehow. I docked a point just for the awful pipettes... I don't need more pipettes but I'm sure some people purchasing this kit will, and I did sorta expect the graduated pipette to at least be functional out of the box, without having to sub in parts or have it fall apart and break the first time I try to use it, which definitely would have happened if I had tried to pick it up by the original bulb.

At first I though I wouldn't like or use them much as planned. I thought for the most part they are just to small. I was wrong. I am happy I picked these. I use them for simple things like lowering the strength of a few solutions I use and for mixing small amounts of full-strength solutions. They are very handy for what I need and something larger wouldn't be as helpful. I would order these again if I would need to replace them. I may order a second set just for when I'm trying to multitask. I find this to be a good value. I have not had any of them fall over even after being a clutz and bumping into them. I will say give them a try and then make up your mind yourself. I think you will be happy with them.

I needed something cool like this for my apartment. I work in a pharmac so I wanted to represent.

These are great Measuring Cylinders.I found them to be accurate, sit flat on the counter and pour cleanly.The small droppers have very fragile tips due to their long thin extension.One was broke on arrival and the seller was VERY QUICK to make it right... Thank YouThe graduated dropper is less fragile because it does not have a long extension tube.I found the brushes to work very well. There were a couple of "hairs" that fell out while I was cleaning them the first time, but nothing since.

This item was supposed to be new. I received it with a stained 0.001g scale and suspicious white crust on one of the pipettes. Please check returns before charging people full price for dirty and possibly contaminated items.
