PYREX 25mL Hubbard-Carmick Specific Gravity Bottle with Standard Taper Stopper

The PYREX 1620-25 25mL Hubbard-Carmick Specific Gravity Bottle is specialized laboratory glassware designed for determining the specific gravity or relative density of materials that are difficult to handle using conventional pycnometers. Its Hubbard-Carmick design makes it particularly suitable for viscous liquids semi-solid bituminous materials and emulsions. The bottle has a nominal capacity of 25mL and is supplied with a 24/12 Standard Taper solid glass stopper. Corning specifically associates the product with ASTM D70 D1429 and D115 test methods.
