250 mL Borosilicate Glass Graduated Cylinder with Cleaning Brush

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.

Excellent. Njmbrs are easy to read, and don't wear off!! Great price

the glass is good quality, love the cleaner brushes that come with it!

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.

This lab glassware is of really fine quality, perfect for everyday use.

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.

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.

These graduated cylinders are an excellent value. The markings are consistent with ASTM class B and they look great. My pipettes work perfectly and I don’t think the graduations are “faded” as some say, I think they are just meant to be transparent. I also like that the larger, numbered grades have a ring that goes almost, but not all the way around the tube. Helpful for estimating on surfaces that aren’t quite level. 10/10 would recommend to anyone who doesn’t need class A etc.

Amazing for using it for essential oils and when requiring precise measurements. So grateful for this kit! Thank you! Delivery went smooth and arrived promptly. Also well packaged and arrived in perfect condition.

C’est la deuxième fois que je commande car le premier est arriver cassé et celui là également ! Ça serrai peut être préférable qu’il soit écrit FRAGIlE sur la boîte ….

The cylinders are of a good size for measuring. The print on the glass is of a good quality that is unlikely to fade with careful use.
