Specific Gravity Bottle

Product Code : SCL-LG-11990

The Specific Gravity Bottle is a laboratory vessel used to determine the density or relative density of suitable liquids through controlled filling and weighing. Also known as a pycnometer or density bottle, it is intended for chemistry, analytical, educational, and research laboratories requiring comparative mass-to-volume measurements.

Product Description

A Specific Gravity Bottle enables a known or controlled volume of liquid to be weighed accurately. Depending on the analytical method, measurements are taken with the bottle empty, filled with a reference liquid, and filled with the test sample. The resulting mass values are used to calculate density or relative density.

The exact capacity, glass composition, stopper design, calibration tolerance, dimensions, and temperature specification of this Science Lab Supplies model are. Buyers can also explore related laboratory glassware for wider analytical and educational laboratory requirements.

How to Use the Specific Gravity Bottle

1. Inspect the bottle and stopper for cracks, chips, contamination, or visible damage.
2. Clean and dry the bottle according to the selected analytical procedure.
3. Weigh the clean, dry bottle using a suitable balance.
4. Fill it with the required reference liquid according to the applicable method, avoiding trapped air bubbles.
5. Condition the liquid at the specified test temperature when required.
6. Wipe the outside dry and record the filled mass.
7. Repeat the procedure with the test sample.
8. Calculate density or relative density using the formula specified by the laboratory method.

Safety note: Wear appropriate personal protective equipment, handle glassware carefully, and follow the chemical-safety procedure applicable to the reference liquid and test sample.

Care & Maintenance

• Clean promptly after each test to prevent residues from affecting subsequent measurements.
• Remove all visible air bubbles before taking measurements.
• Keep the stopper and bottle together when they form a matched measuring assembly.
• Avoid thermal shock, scratches, chips, and mechanical impact.

Frequently Asked Questions

What is a Specific Gravity Bottle used for?

A Specific Gravity Bottle is used to determine the density or relative density of suitable liquids by weighing a controlled volume of the sample.

Is a Specific Gravity Bottle the same as a pycnometer?

Yes. The terms specific gravity bottle, pycnometer, and density bottle are commonly used for laboratory vessels designed for density or relative-density measurement.

How does a Specific Gravity Bottle work?

The bottle is weighed empty and then with a known or controlled volume of reference liquid and test sample. The measured masses are used in the calculation specified by the analytical method.

What is the capacity of this Specific Gravity Bottle?

The exact nominal capacity of this Science Lab Supplies product is. Capacity should be verified before ordering.

Why should air bubbles be removed before measurement?

Trapped air can change the actual volume of liquid inside the bottle and introduce error into density or relative-density calculations.

Can a Specific Gravity Bottle be used in schools and colleges?

Yes. It is suitable for supervised chemistry and physics practicals involving density, relative density, mass, volume, and quantitative measurement.
