Graduated Cylinder, 10ml - Class A Tolerance ±0.10ml - Hexagonal Base - Blue Graduations - Borosilicate 3.3 Glass - Eisco Labs

Very nice and easy to read. Perfect for dosing aquarium chemicals.

Excellent markings. Sturdy and thick glass.

As described

Well made quality product, but the opening is quite narrow. The previous cylinder I had had a flared opening making it easier to pour into. Works but isn't the best design.

Arrived in good condition - no cracks or chips.Why did I want such a small measuring glass? Reason: wanted to mix small amounts (6, 8, or 10 ozs.) of 2 cycle engine fuel. I only use my gas trimmer twice a month. Prefer not to have a gallon of 40:1 fuel mixture sitting in my shed for 6-8 mos. I converted the mixture table into milliliters of oil per oz. of gas. I mix only enough 2 cycle fuel to complete the job. No need for two different gas cans.

Tested accuracy against NeoMed, Vesco, and medela syringes and against OniLab Pipettor and it was consistently 0.2ml off. That is 5ml of fluid read 5.2 on the cylinder. (Yes i sighted it at eye level and measured the bottom of the meniscus )

Used to determine powder density. Worked great.

For something fragile it’s shipped in a plastic bag. Good product, I’ve broken a couple of them and that’s on me. I keep buying more though.
