These specific-gravity bottles are flasks which purposefully made to hold a known volume of liquid at a specified temperature.

• Made up of borosilicate glass
• Non adjustable
• Cap size 14/12

The bottle is weighed, filled with the liquid whose specific gravity is to be found, and weighed again. In these bottles weld type pycnometer devised is attached to measure specific gravity of volatile liquids. The [ST] glass stopper and cap reduce evaporation.
