The Vibro-Deairator for Rice Test is designed for consistent shaking of Rice test vacuum pycnometers while freeing the lab technician. It is a useful deaeration device for specific gravity tests of fine aggregates (ASTM C 128) and soils (ASTM D 854), for sample preconditioning per ASTM D 4867 and AASHTO T283. Case has built-in 0 to 99 min., 59 sec. digital timer with 0.25 sec. accuracy, vibration speed control, and a 3-position switch for manual or timed operation-all front panel mounted for easy use. Speed control allows setting of agitation to avoid stripping of asphalt. This unit comes with fitted top and bottom plates for exact fit with our pycnometers.
Special "speed knobs" quickly secure the pycnometer. After a few loosening turns, they tilt and slide for fast removal. The unit is electrically grounded and fused. The aluminum case has rubber feet; no mounting is required.
Overall dimensions: 13x14x19" (330x356x483mm), WxDxH.
