The determination of the specific gravity and density of fine soils is developed through three different operations: the sample, introduced in the specific gravity bottle, has to be thermostatically normalized by immersion in a suitable water bath complete with Adjustable tray and Cover with cooling coil, then de-aired using a desiccator connected to a vacuum pump and, finally, weighted. Glass bottles complete with capillary vent stopper.

Ltekonline are the manufacturers of Specific Gravity Bottles used to demonstrate engineering principles in Engineering Colleges, Engineering Schools and Soil Testing for Engineering Teaching Lab in Universities
