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. It suits chemistry, physics, pharmacy and soil-testing practicals wherever mass-to-volume comparisons are needed. Science Lab Supplies can deliver it from Ambala, India to school and college laboratories, research groups, tender contractors and distributors.
Specifications
Every fact about this density bottle sits in its own table row. In brief, it is a reusable glass bottle closed with its own stopper; the clear glass lets you check the filling level, cleanliness and any trapped air bubbles before weighing, while capacity and stopper design are confirmed on the quotation.

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, weighed on a Balance Electronic 0.1MG where high accuracy is needed.
- 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.
Top the bottle up with a Glass Dropper Pipette 6, remove every air bubble, wipe the outside dry, and keep each bottle with its own stopper. Reference water can be held in a Borosilicate Beaker.
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, Science Lab Supplies 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. A density-practical order can start with a note on the contact page or a list in the enquiry cart; formal institutional purchases follow 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 such as 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 in teaching and testing laboratories.
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 or relative density comes out wrong.
Who supplies the Specific Gravity Bottle?
It is sourced through Science Lab Supplies, an Ambala, Haryana supplier that quotes single bottles or class quantities for teaching and testing laboratories and tender contractors, with related glassware on the same document.
Related Density, Viscosity and Weighing Apparatus
Density feeds into viscosity and surface tension calculations, depends on careful weighing and temperature control, and is also measured for solids. The items below share that physical properties bench, from capillary glassware to balances and density cubes, and can be quoted together with the bottle.
- Ostwald Viscometer — U-shaped glass capillary timed between two marks for relative viscosity.
- Stalagmometer — manual drop-count glassware for the relative surface tension of liquids.
- Nicholson Hydrometer — brass-sheet hydrometer offered in medium and large sizes.
- Density Cube Set — nine 25 mm cubes from brass to acrylic, in a wooden box.
- Balance Electronic — stainless steel weighing pans, running on a 9V battery or AC.
- Laboratory Thermometers — graduated alcohol thermometer for -10 to 100 °C.
- Weighing Bottle — clear glass with a ground glass joint and stopper.
