Vacuum pycnometers work with rice testing to determine the maximum specific gravity of bituminous paving mixtures. In addition, it determines maximum aggregate size up to 3/4″. Available in 2,000g and 6,000g capacities.  The vibrating table will accept the standard vacuum pycnometer (2,000g). As well as a 4,000ml heavy wall filter flask without any optional flask holders. The heavy duty vibrating de-airing agitator keeps sample material loose for more reliable test results.  The unit features strong, rugged vibrators and sturdy bases having integral on/off switches.  The vacuum saturation canister conditions specimens before testing. Its acrylic lid has ports for a vacuum pump and manometers. With the vacuum level adjusting valve the vacuum adjusts to 30mm on sample.
