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

Perfect for the distillery. Well made, heavy and thick glass.

Great quality glass. The markings are clear and printed in a large font. The brush and second GC is also nice for the price of just one.

I do a number of dilutions for detailing work and I also mix food components such as oils for consumption. My need was for a few different sizes of cylinders and this set works very well. For my uses, it is important that these cylinders be able to hold chemical components without leaching as well as food products and maintain cleanliness. This set covers all my needs. Very pleased.

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.

Good set

I'm very happy with this graduated cylinder set. It's actually better quality than I anticipated. I bought this set specifically even though it was a little more expensive than some of the others because it was the only affordable one that actually showed the wall thickness of the glass. And I'm not disappointed in the thickness, it does not feel like it will casually break. I'm wanted glass instead of cheaper plastic so the cylinders and especially pippets won't absorb checmicals at all. That means I can quickly rinse them out and use them on the next chemical. The pippets are nice and long which will come in handy for my art use of these so I can easily squirt liquids under items I've laid down on paper. I was having trouble using the shorter standard length ones. Loving it so far.

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.

Inspect every piece for chips or defects. Didn’t notice one of the pipettes was chipped till the return window closed. Set comes in a flimsy cardstock box and was shipped in a paper mailing envelope.
