This smaller Vacuum Pycnometer is used in the Rice Test to determine the specific gravity of bituminous paving mixtures with maximum aggregate size up to 3/4” (19.1 mm). This 4.5 liter size will handle a 2,000 gram sample. The transparent lid on the pycnometer allows the operator to observe the bubble release from the asphalt sample during the test. A second volumetric lid, tapered with a capillary bore, is provided so the unit can be used as a volumeter for determining specific gravity of compacted bituminous mixtures. Vacuum is achieved by using the accessory aspirator or laboratory vacuum pump.
The Aspirator Filter Pump used for high performance vacuum filtrations under both high and low water pressure conditions.
