ASTM E237

This specification covers microvolumetric glass vessels (volumetric flasks and centrifuge tubes) widely used in microchemistry. The volumetric flasks shall conform to the design and dimensional requirements specified for the two styles illustrated herein. The centrifuge tubes shall be either of the four types, as follows: plain with a conical bottom; stoppered with a conical bottom; stoppered and graduated with a conical bottom; and plain with a cylindrical bottom. The centrifuge tubes shall also conform to the design and dimensional requirements specified for the four types illustrated herein.
