Rice Testing Shaker for Automatic De-airing of Vacuum Pycnometers

The CANTROL Rice Testing Shaker is a high-performance laboratory agitator engineered to provide the consistent, automatic agitation required for the Theoretical Maximum Specific Gravity (Rice Test) of bituminous paving mixtures. In a field where precision is paramount, manual agitation of vacuum pycnometers can lead to inconsistent results and operator fatigue. Our shaker eliminates these variables, delivering a standardized vibration pattern that ensures air is effectively removed from the asphalt-water interface.

Engineered for Precision and Repeatability

At the heart of the Rice Testing Shaker is a variable vibration speed controller, allowing lab technicians to set the optimum agitation level based on sample size and material density. The unit features a built-in digital timer (adjustable from 0 to 99 minutes) with a high accuracy of ±0.5 seconds. This level of control is essential for labs performing ASTM D2041 and AASHTO T 209 testing, where repeatable mechanical agitation is often the preferred method over manual shaking.

Rugged Construction and Multi-Disciplinary Use

Built for the rigorous environment of a busy pavement laboratory, this shaker utilizes heavy-duty vibrators and quick-release fasteners that securely hold canisters in place. While primarily used for asphalt, it is also an invaluable de-airing device for:

• Specific Gravity of Fine Aggregates: Compliant with ASTM C128.

• Specific Gravity of Soils: Compliant with ASTM D854.

• Sample Preconditioning: Ideal for moisture sensitivity testing per AASHTO T 283 and ASTM D4867.

Maximize Laboratory Efficiency

The automatic operation of the CANTROL Rice Testing Shaker significantly reduces labor costs by freeing up technicians to perform other tasks while the de-airing process is underway. Its compact, bench-top design allows it to fit seamlessly into any laboratory layout without sacrificing power or performance. By integrating this shaker into your workflow, you ensure that your lab meets the highest standards of quality control and asphalt mix design.
