2000g Vacuum Pycnometers

Both large capacity vacuum pycnometers include an aluminum volumetric canister, volumetric lid, flat Plexiglass vacuum lid with O-ring, volumeter, release valve, fittings, a metal aspirator with 3/8 inch IPT fittings, and 6 ft. of hose.

The A-516 is a vacuum pycnometer used in Rice Testing for bituminous mixes with a maximum aggregate size of ¾ in. (19.1 mm). The 2000 g capacity vacuum pycnometer has a 4.5 liter (1.2 gal) capacity. A transparent lid on the pycnometer allows the operator to observe the bubble release from the asphalt sample during the vacuum test. A second volumetric lid of machined aluminum, tapered with a capillary bore, is provided so the unit can be used as a volumeter for determining the specific gravity of compacted bituminous mixes.

The A-518 is a 1500-gram capacity vacuum pycnometer with a 4-in. deep chamber. This vacuum pycnometer is used for mixes with aggregate sizes up to 0.5 inches.
