• Use to determine specific gravity by measuring the difference between an empty and filled bottle and dividing by an equal volume of water.
• Made from high-quality borosilicate 3.3 glass.
• Perforated ground stopper and flat bottom for spill prevention.
• Superior chemical durability and heat tolerance. Designed for use in professional laboratories, but is an ideal choice for science classrooms and household use.

Specific Gravity Bottle is ideal for use in physics and chemistry experiments to determine the density of liquids. Made from light-blown borosilicate glass. Spherical pattern not adjusted. With flat bottom and perforated ground stopper. Inner diameter at bottle mouth: 10mm; overall size: 1.15" dia x 2.75" tall with stopper (1.75" tall without stopper). Capacity: 10mL

Autoclavable, with superior chemical durability. Low temperature gradient- can withstand high temperatures & thermal shocks. Eisco Labs Borosilicate glass has the following heat tolerances: Strain Point 515°C | Annealing Point 565°C | Softening Point 820°C
