Product Description
Dissolve tablets, powders and viscous samples completely before you read the volume. A mixing bulb in the neck adds headspace so contents can be shaken and swirled thoroughly, giving more reliable results in dissolution testing, assay preparation and content uniformity work.
This listing is for Kimble catalog number 623020-1000: KONTES 1000 mL Volumetric Mixing Flask With Bulb, Wide Mouth and Heavy Wall. The bulb sits between the stopper and the capacity ring and holds roughly one tenth of the body volume. Flasks comply with ASTM E288, Class A, are borosilicate glass 3.3 and are calibrated to contain, each with a marking spot and pennyhead glass stopper. Choose standard, wide mouth for easy solid addition, or wide mouth heavy wall for extra durability. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
