25ml Graduated Cylinder, Borosilicate 3.3 Glass, Single Metric Scale, Class B, Karter Scientific 246G7 (Pack of 2)

This graduated cylinder features easy to read graduations and a sturdy as easy to grip design. This product was offered at an affordable price, thank you for providing a great high-quality product!

Not all graduated cylinders are the same. Some have the graduations painted on the outside, and over time thy can be chipped or worn away. Karter graduates have the graduations fired into the glass for permanency. Borosilicate glass means no worry about hot liquids in a gold glass graduate. Excellent quality.

Seems like a quality product. I use the 100 ml as a hydrometer jar and my hydrometer fits perfectly. I often fill with hot wort and put in freezer to cool down for an accurate reading, no problem. Just don't knock it over on a granite countertop; this is my second one.

Good cylinder. I use it for measuring out liquid electrolytes to add to my drinks. Works well and the measurements appear to be accurate.

The product came in good condition, and is of excellent quality.

Overall I'm happy with this purchase. For the price, the glass is pretty thick and the product feels substantial. Having said that, there are a few caveats to this product.First, the product listing is incorrect. The product is advertised as "Class A." Per ASTM E1272, a "Class A" 100ml graduated cylinder must be accurate to within +/- 0.5 mL. This product is labeled as having +/- 1.0 mL accuracy, which is "Class B." Aside from this product listing being technically incorrect, I don't think this is a big deal. I needed something reasonably accurate for calibrating peristaltic pumps. For my application, this product hits the sweet spot between price and function. If you need something with a certificate of accuracy, I don't think this is the container for you. However, if you truly need that level of accuracy and precision, I doubt you'd be looking at glassware on Amazon.com. You'd likely be buying from one of the big players in the scientific community (Sigma Aldrich, Fisher Scientific, etc). For me, I needed something reasonably accurate that was more precise than a simple measuring cup, and this fit the bill nicely for a decent price.Second, the cylinder has marks every mL, but it has no marks at all below 10 mL. This is not a problem for me, as I regularly measure between 50 and 100 mL. Just a useful piece of information of which to be aware.If it weren't for the listing inaccuracy, I'd rate this product as 5 stars. It's a reasonably accurate sturdy piece of glassware for a good price. Overall, very satisfied with the purchase.

Item as described. Works well. No issues.

Great quality, excellent value. I keep finding new uses for these!
