"Gilson offers three types of vacuum pycnometers to determine maximum specific gravity. All three feature a transparent cover for observation of bubble release during testing. Standard components include vacuum hose, quick-disconnect, and a 3\/8in (9.5mm) threaded aspirator vacuum source."," SG-16A 2000g Pycnometer meets both ASTM D 2041 and AASHTO T 209. Aluminum volumetric canister is 7.5in dia. x 6in D (191x152mm) and tests a maximum 2,000g (4.4lb) sample, sufficient for mixes with up to 3\/4in (19.1mm) aggregates. A transparent vacuum lid and a second tapered aluminum lid with capillary bore are included, to allow canister to be used as volumeter for determining specific gravity of compacted bituminous mixtures. Est. Ship Wt.: 15lb (7kg)."," SG-17 1500g Pycnometer (3.3lb) sample is 4in (102mm) deep, sufficient for mixes with up to 1\/2in (13mm) aggregates. Est. Ship Wt.: 12lb (6kg)."," SG-15 Type F Pycnometer meets ASTM D 2041 and AASHTO T 209. The large, 10L capacity pycnometer is suited for mixes with aggregates up to 2in (51mm). High-strength plastic vessel with 9.38in (238mm) I.D. has four metal clamps and an O-Ring seal to prevent leakage. An adjustable valve controls water level, and a perorated plastic shelf is included. The shelf supports three 4in (102mm) specimens. Overall dimensions: 10.75x13.3in (273x338mm), Dia.xH. Est. Ship Wt.: 15lb"
