Gilson's Vacuum Pycnometers are for determining maximum specific gravity in bituminous paving mixtures. The SG-16A and 18A models meet ASTM D2041 and AASHTO T 209 standards and are used with the SGA-5R Rice Shakers for Specific Gravity & Asphalt Rice Test.
SG-16A 2,000g Pycnometer ensures accurate specific gravity measurements. This precision-machined aluminum volumetric canister is 7.5x6in (191x152mm) dia.xD and tests a maximum 2,000g (4.4lb) sample, sufficient for mixes with up to 3/4in (19.1mm) aggregates. A transparent vacuum lid, second tapered aluminum lid with a capillary bore, 3/8in (9.5mm) threaded vacuum aspirator, and tubing 3/8x48in (9.5x1,219mm) ID x L are included, allowing the canister to be used as a volumeter for determining the specific gravity of compacted bituminous mixtures.
SG-18A 4,000g Pycnometer features increased sample capacity over SG-16A. Its 7.5x9in (191x229mm) Dia.xD Aluminum volumetric canister has enough volume for specimens up to 4,000g. Included transparent acrylic Vacuum Lid and Aluminum Lid with capillary bore are identical to SG-16A lids for use in specific gravity determinations of compacted bituminous mixtures. Vacuum tubing 3/8x48in (9.5x1,219mm) ID x L, quick-disconnect, and a 3/8in (9.5mm) threaded vacuum aspirator are also included.
SG-16A: 7.5 x 6.375in (191 x 162mm) Dia.x H
SG-18A: 7.5 x 9.375in (191 x 238mm) Dia.x H
SG-16A: 12.0lb (5.44kg)
SG-18A: 17.0lb (7.71kg)
