Vintage Kimax Borosilicate Glass Volumetric Flask 28015, Class B, 1000mL, ±0.60mL While it is not marked which class, (A or B), on the flask, I was able to determine which it would be classed as by doing a bit of research on the tolerance rating. I really don't know a lot about this, other than the information I was able to find, on the specifications, but it looks like it is in great condition. This is an older flask, that came from an estate sale, but they are still being manufactured today.

Estate lot in good clean condition.
