Density Bottle

Density Bottle – Precision Instrument for Liquid Density Measurement

A Density Bottle, also known as a Specific Gravity Bottle, is a highly accurate laboratory glassware used to determine the density and specific gravity of liquids. It is commonly used in chemistry, physics, and industrial laboratories where precise measurements of liquid density are required. The bottle is typically made of borosilicate glass, ensuring chemical resistance, durability, and thermal stability.

Key Features

✔ High-Precision Measurement – Designed to provide accurate density calculations.
✔ Borosilicate Glass Construction – Resistant to chemical corrosion and temperature variations.
✔ Narrow Neck with Stopper – Minimizes evaporation and ensures accurate volume measurement.
✔ Capillary Hole in Stopper – Allows excess liquid to escape, ensuring precise filling.
✔ Available in Different Capacities – Common sizes include 25ml, 50ml, and 100ml for various applications.

How the Density Bottle Works

1. Weigh the Empty Bottle (W1) – Measure the mass of the clean, dry bottle.
2. Fill with Liquid & Weigh Again (W2) – Fill the bottle with the test liquid and weigh it.
3. Repeat with Water (W3) – Clean the bottle, fill it with distilled water, and weigh it again.​

Applications of Density Bottle

• Scientific Research – Used in physics and chemistry laboratories for fluid analysis.
• Industrial Quality Control – Measures density of oils, chemicals, and solutions in industries.
• Educational Purposes – Helps students and researchers learn about fluid properties.
• Food & Beverage Industry – Determines density of syrups, juices, and alcohol solutions.
• Pharmaceutical & Chemical Analysis – Ensures precise formulation of liquid drugs and solutions.
