The Vacuum Pyknometers (Yale Pyknometer) are used for determining the theoretical maximum specific gravity of uncompacted bituminous paving mixtures.
The Pycnometer 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 is manufactured from transparent plastic and supplied complete with vacuum gauge on the transparent lid with O-ring.
4,3 L Vacuum Pyknometer is included aluminum volumetric canister and volumetric lid and transparent vacuum lid with O-ring and supplied complete with vacuum gauge.
Vacuum Pumps are supplied with 3m plastic tube (Ø8mm) and 2 pcs. Clamps.
Vacuum Gauge, Analog, Scale Range (-100/0 kPa), Accuracy (1.0 % of scale range), 1 kPa graduated, Ø63 mm. Supplied with a valve, 4-way dispenser and muffler.
Vibra-Dearator, Vacuum Pump and filter flask or air drying unit / water trap should be ordered separately.
