Specific Gravity Bottles
Product Code : EL-STLE-10411
Specific Gravity Bottles (code EL-STLE-10411) are glass bottles with a capillary vent stopper, used in the soil laboratory to find the specific gravity and density of fine soils. A soil sample placed in a bottle is brought to a steady temperature in a water bath, freed of trapped air in a desiccator evacuated by a vacuum pump, and then weighed.

What Are the Specific Gravity Bottles Used For?
The specific gravity of soil solids compares the mass of the soil particles with the mass of an equal volume of water, and it is needed when void ratio, porosity and degree of saturation are worked out from other test results. The fine soil sample goes into the bottle, which is closed with its capillary vent stopper so that it holds the same volume at every weighing. The bottle is held at a set temperature in a water bath with adjustable tray and cooling-coil cover, trapped air is drawn off in a desiccator connected to a vacuum pump, and the bottle is then weighed.
What to Specify When Ordering
- Quantity — the number of specific gravity bottles required.
- Accessories — whether the water bath with adjustable tray and cooling-coil cover, the desiccator and the vacuum pump are needed as well.
Frequently Asked Questions
What are Specific Gravity Bottles used for?
They serve to find the specific gravity and density of fine soils, with the soil sample held in the glass bottle while it is conditioned, de-aired and weighed.
What kind of stopper do the bottles have?
Each glass bottle is closed with a capillary vent stopper. Excess liquid escapes through the capillary, so the filled bottle holds the same volume every time it is weighed.
Which accessories are used with the bottles during a test?
A water bath with adjustable tray and cover with cooling coil normalises the temperature of the sample, and a desiccator connected to a vacuum pump de-airs it. Both are offered as accessories.
Why is the sample de-aired before weighing?
Air trapped between soil particles takes up space that should be filled with liquid, so removing it under vacuum in the desiccator stops the specific gravity from being understated.
