The Vacuum pycnometer (Yale Pycnometer) is used for determining the theoretical maximum specific gravity of compacted bituminous paving mixtures.
The apparatus can also be used for the calculation of the percent of air voids in compacted bituminous mixtures and the amount of bitumen absorbed by the aggregates.
The Vacuum pyknometer B1870 is manufactured from transparent plastic and supplied complete with vacuum gauge(G435) on the transparent lid with O-ring.
4,3 L capacity vacuum pyknometer B1872 is included aluminum volumetric canister and volumetric lid and transparent vacuum lid with O-ring and supplied complete with vacuum gauge(G435).
Vacuum pumps are supplied with 3m plastic tube (Ø8mm) and 2 pcs. Clamps.
