Soil Specific Gravity Test Equipment: Pycnometers & Flasks
Match the Apparatus to the Method
Specific gravity testing relates the mass of soil solids to an equivalent volume of water, supporting classification and density calculations. Select apparatus around the governing method, specimen size and required precision rather than by capacity alone.
Confirm the volumetric requirements of the chosen procedure before ordering, and verify whether a thermometer, water bath or weighing arrangement is specified as part of the complete setup.
Compare Flasks and Supporting Bench Equipment
Compare the Hubbard-Carmick Specific Gravity Bottle, 24mL and the 25mL version by capacity and graduations. The Le Chatelier Specific Gravity Flask is a separate flask design; check its intended application before substituting it for a bottle-style apparatus.
Supporting bench equipment completes the setup. Review the Specific Gravity Bench for Weighing Samples and the 30-gallon Specific Gravity Water Tank against the weighing and temperature-control requirements of the method. Verify capacity and mounting details before ordering.
Verify What Each Listing Includes
Flasks, bottles, benches, tanks and heaters are listed separately; a complete system is not assembled by a single product unless its description states so. Check volumetric tolerances, calibration documentation and compatibility between components.
Confirm thermometer and weighing requirements against the governing method, and match any temperature-control equipment to the tank or bath being used rather than assuming interchangeability.
Prepare Specimens and Record Results
Follow the method's specimen preparation, de-airing and temperature requirements, and record the measurements needed for the specific gravity calculation. Clean and dry glassware between tests as the procedure requires.
Specific gravity of soil solids is distinct from aggregate and asphalt gravity testing, which use different apparatus and methods. For those materials, review the dedicated aggregate and asphalt categories. Confirm the soil-specific method before completing the order.
