Specific Gravity Measuring Bottle Manufacturer,Supplier and Exporter in India

Product Code : SCL-B-12571

The Specific Gravity Measuring Bottle is a laboratory glass bottle used for determining the density or relative density of liquids by weighing a known volume of sample. It is suitable for school chemistry labs, college practicals, analytical laboratories, quality-control training, distributors, and institutional procurement buyers.

Product Description

Specific Gravity Measuring Bottle from School Equipments India is intended for supervised density and relative-density experiments in chemistry and physical science laboratories. The bottle helps students connect mass, volume, density, and specific gravity through direct weighing rather than digital sensor readings.

A typical specific gravity bottle, also called a pycnometer or density bottle, has a precisely defined volume and a close-fitting stopper with a fine capillary opening. Exact capacity, glass type, calibration temperature, tolerance class, stopper type, dimensions, and certificate availability should be confirmed before publication, quotation, or tender submission.

Key Features

• Density determination use: supports measurement of liquid density by weighing a filled bottle of known volume.
• Specific gravity comparison: helps compare sample density with water under controlled temperature conditions.
• Pycnometer-style design: typically uses a stopper with capillary opening to release excess liquid and trapped air.
• Analytical teaching value: supports lessons on mass, volume, density, relative density, and measurement error.
• Manual operation: requires a balance and temperature control, not an electrical measuring system.
• Reusable laboratory glassware: can be cleaned, dried, inspected, and reused after compatibility checks.
• Specification-safe procurement: final capacity, tolerance, glass grade, and certification must be verified before order.

Technical Specifications

What's Included in the Kit

• 1 × Specific Gravity Measuring Bottle

Applications / Uses

• Determining density of compatible liquids by mass and known volume
• Comparing specific gravity or relative density with water
• Teaching mass-volume-density relationships in chemistry practicals
• Supporting analytical chemistry and quality-control training exercises
• Checking density changes in salt, sugar, glycerol, or approved laboratory solutions
• Supporting tender-based procurement for chemistry lab glassware

How to Use the Specific Gravity Measuring Bottle

1. Clean and dry the bottle and stopper before use.
2. Weigh the empty bottle with stopper on a suitable balance.
3. Fill the bottle with distilled water at the specified test temperature.
4. Insert the stopper so excess liquid escapes through the capillary opening.
5. Wipe the outside dry and weigh the filled bottle.
6. Empty, rinse, and fill the bottle with the test liquid at the same temperature.
7. Weigh the bottle with the test liquid using the same balance.
8. Calculate density or specific gravity according to the laboratory method.

Safety note: Use only compatible liquids. Wear suitable PPE, avoid air bubbles, do not pipette by mouth, and handle volatile, corrosive, flammable, or hazardous samples according to the SDS and laboratory SOP.

Care & Maintenance

• Clean immediately after use because residue affects bottle volume and weighing accuracy.
• Keep the capillary opening clear; do not push hard metal tools through it.
• Dry fully before storage to prevent water marks and contamination.
• Store the bottle and stopper together in a protected cabinet to prevent mismatch or breakage.

Frequently Asked Questions

What is a Specific Gravity Measuring Bottle used for?

A Specific Gravity Measuring Bottle is used to determine the density or relative density of compatible liquids by weighing a known bottle volume filled with water and then with the test liquid.

Is a specific gravity bottle the same as a pycnometer?

Yes. A specific gravity bottle is commonly called a pycnometer or density bottle. It is used for density and relative-density determination by the weighing method.

What capacity is available?

The capacity is not confirmed. Add 25 mL, 50 mL, 100 mL, or another capacity only after checking the final School Equipments India quotation or datasheet.

Why does the stopper have a capillary opening?

The capillary opening allows excess liquid and trapped air to escape when the stopper is inserted. This helps define a consistent filled volume before weighing.

Does it meet ISO 3507?

ISO 3507:1999 is a relevant standard for laboratory pyknometers. Compliance should be claimed only if School Equipments India supplies a supporting certificate or datasheet.

Can students use it in school chemistry labs?

Yes. It is suitable for supervised school and college chemistry laboratories when teachers control filling, wiping, weighing, temperature consistency, liquid compatibility, and glassware safety.
