The SGA-5R Gilson Rice Shaker for Specific Gravity & Asphalt Rice Test performs consistent, automatic agitation of Asphalt Rice Test vacuum pycnometers for deairing, freeing lab technicians for other duties. It is also a useful de-airing agitator for specific gravity tests of fine aggregates (ASTM C128) and soils (ASTM D854), as well as sample preconditioning per ASTM D4867 and AASHTO T 283.
The Rice Shaker features a built-in 0-99 min., 59 sec. digital timer with ±0.25 second accuracy, a vibration speed controller and a three position switch for manual or timed operation—all front panel mounted for easy use. Variable speed settings closely control agitation to avoid stripping of asphalt.
Gilson's exclusive EZ Clamp System quickly secures pycnometers. Push the buttons, slide into place and a quick twist secures the container. SGA-11 Alternate Clamping System is available separately. The kit includes rods and threaded speed knobs that tilt to slide freely on or off the rods, then tighten with a few turns to secure clamping. SGA-12 EZ Clamp Upgrade Kit is also available to retrofit older Gilson Rice Shakers to the EZ Clamp system.
The SGA-5R includes fitted top and bottom plates for exact fit with SG-16A or SG-18A Aluminum Pycnometers. Order SGA-7 Adapter Set for use with high capacity plastic SG-15 Pycnometer. SGA-8 Adapter Set is required for use with GW-74, GW-75 or GW-76 Filter Flasks, SG-500 Volumetric Flask, SG-24 LeChatelier Flask, or SG-2 Mason Jar Pycnometer. Inquire for fitting other containers. MA-170 Digital Residual Pressure Manometer precisely measures applied vacuum during testing. NIST certified model is available as MA-170C. SGA-5RT has modified vibration characteristics to meet Texas DOT requirements.
