The Vacuum Pyknometer Test Set determines the theoretical maximum specific gravity and density of uncompacted bituminous mixtures. The system removes trapped air from the sample by applying controlled vacuum conditions. This allows laboratories to determine the density of the mixture with minimal air voids.
- 10 litre capacity: The stainless steel pyknometer supports testing of relatively large asphalt samples.
- Vacuum-resistant construction: The durable body withstands vacuum pressure and intensive laboratory use.
- Effective air removal: The vibro-deaerator continuously moves the sample and helps release trapped air bubbles.
- High-performance vacuum: The vacuum pump provides the low-pressure conditions required for the test.
- Pressure monitoring: The vacuum gauge allows the operator to monitor vacuum conditions throughout the procedure.
- Complete test equipment: The set includes the pyknometer, vibro-deaerator, vacuum pump, gauge and connection hose.
- Additional accessory: A 250 ml filter flask supports auxiliary vacuum and control procedures.
- Standards support: The system supports maximum density testing according to ASTM D2041/D2041M, EN 12697-5 and AASHTO T209.

What Is a Vacuum Pyknometer?
The Vacuum Pyknometer determines the theoretical maximum specific gravity and density of uncompacted bituminous mixtures. The system removes trapped air from the sample by applying vacuum. Therefore, laboratories can calculate the density of the mixture under minimum air-void conditions.
Maximum density provides important data for asphalt mixture design. Laboratories also use this value when calculating the percentage of air voids in compacted mixtures. ASTM D2041 covers the theoretical maximum specific gravity and density of uncompacted asphalt mixtures, while EN 12697-5 and AASHTO T209 describe related maximum density procedures.
10 Litre Vacuum Pyknometer
The system includes a 10 litre capacity pyknometer suitable for asphalt laboratory applications. Its robust construction supports repeated use under vacuum conditions.
A secure cover helps maintain the required vacuum during testing. Connection points also allow the vacuum pump, gauge and hose to operate as an integrated system. As a result, the operator can manage the test under controlled conditions.
Vacuum Pump and Pressure Control
The vacuum pump reduces the pressure inside the pyknometer. This process encourages trapped air between aggregate and bituminous mixture particles to escape.
The vacuum gauge continuously indicates the pressure level during testing. Consistent pressure monitoring helps laboratories maintain similar conditions between different samples. Durable vacuum hoses provide secure connections between the main components.
Vibro-Deaerator System
The Vibro-Deaerator continuously moves the pyknometer during the vacuum process. Mechanical vibration helps trapped air bubbles rise and escape more efficiently.
This movement improves the effectiveness of the vacuum procedure and reduces the need for manual agitation. It also supports repeatable testing by providing consistent sample movement during deaeration.
Complete Test Accessories
The Vacuum Pyknometer Test Set works with a vacuum pump, gauge, vibro-deaerator and connection hoses. A 250 ml filter flask is also included for supplementary laboratory operations.
Providing the required components as a complete system simplifies test preparation and helps reduce compatibility problems between individual accessories.
Maximum Density Testing According to Standards
The Vacuum Pyknometer Test Set supports maximum density determination according to ASTM D2041/D2041M, EN 12697-5, AASHTO T209 and applicable maximum-density test methods.
Overall, the system combines a durable pyknometer, controlled vacuum and effective deaeration. Therefore, asphalt laboratories can determine theoretical maximum density under reliable and repeatable testing conditions.
