Product Code : SCL-LG-11990
Specific Gravity Bottle (SKU SCL-LG-11990), also known as a pycnometer or density bottle, is a stoppered glass vessel for finding the density or relative density of a liquid by weighing a fixed volume of it. Chemistry, physics, pharmacy and soil-testing practicals use it wherever mass-to-volume comparisons are needed. Schools, colleges, research laboratories, tender contractors and distributors can obtain it from Science Lab Supplies, which supplies it from Ambala, India.
Specifications
The bottle is made of glass, which lets the user check the filling level, cleanliness and any trapped air bubbles before weighing, and is closed with its own stopper. It is reusable when cleaned properly. Capacity and stopper design are confirmed on the quotation for the model offered.

| Function | Determining density or relative density of liquids |
| Supplied by | Science Lab Supplies, Ambala, India |
Applications and Experiments for the Specific Gravity Bottle
The bottle is weighed empty, then filled with a reference liquid such as water, then with the sample; the three masses give the relative density. Because the volume is fixed each time, the method is simple enough for school practicals yet precise enough for pharmacy, chemistry and soil laboratories.
- School and Class 11 physics or chemistry: density and relative density of liquids.
- B.Sc. physical chemistry: densities needed for viscosity and surface tension calculations.
- B.Pharm physical pharmaceutics: density determination of liquids.
- Civil engineering soil mechanics: density-bottle method for specific gravity of soil solids.
Remove every air bubble before weighing, wipe the outside dry, and keep each bottle with its own stopper, since the pair forms one measuring assembly.
Standard Scope of Supply
The supply consists of one Specific Gravity Bottle together with its stopper. An analytical balance, thermometer, reference liquid, pipettes and cleaning accessories are not included, and any of them can be requested on the same quotation if your laboratory needs them.
Packing, MOQ and Lead Time
Ask for one bottle or a set for every student pair; the quotation returned will state packing, delivery time and price for that number. As a laboratory glassware supplier in India, we can combine it with viscometers, pipettes and other chemistry lab equipment in one quote.
Science Lab Supplies is a registered exporter holding an Importer-Exporter Code and can ship to buyers in Nigeria, Kenya, Ghana, Ethiopia, Tanzania and Uganda. Questions about quantity or fit can be sent from the contact page; to list several products use the enquiry cart, and for tenders see the lab tender page.
Frequently Asked Questions
What is a specific gravity bottle used for?
It is used to measure the density or relative density of a liquid by weighing a fixed volume of the sample and comparing it with the same volume of a reference liquid, usually water.
Is a specific gravity bottle the same as a pycnometer?
Yes. Specific gravity bottle, pycnometer and density bottle are common names for the same kind of vessel used for density and relative-density measurement.
Why must air bubbles be removed before weighing?
A trapped bubble takes up space meant for liquid, so the bottle holds less sample than intended and the calculated density comes out wrong.
Who supplies the Specific Gravity Bottle?
Supply is handled by Science Lab Supplies from Ambala, India. Teaching laboratories, testing laboratories and tender contractors can order single bottles or class quantities with related glassware.
Related Physical Properties Glassware
Density is rarely measured for its own sake: it feeds into viscosity and surface tension calculations, and solids are weighed in closed containers. The four items below share that physical properties bench and can be quoted together with the density bottle.
- Ostwald Viscometer — relative viscosity, which needs the liquid densities.
- Stalagmometer — surface tension by the drop method.
- Weighing Bottle — closed container for weighing solid samples.
- Glass Dropper Pipette 6 — tops up the bottle drop by drop.
