To seal the sample effectively and consistently, all NextGen rotorless rheometers and curemeters use a high-pressure pneumatic system. During gap closure, the high-capacity pneumatic system provides up to 8 bar of nominal pressure on the sample. Mechanical bearings are used to guarantee efficient load transfer from the system to the sample without incurring load frame losses. Direct measurements and records are made of the actual sealing pressure. The test specimen is tightly contained by this high-pressure automated sample containment, which also eliminates operator dependence. For materials that experience positive or negative volumetric changes during curing as well as extremely stiff materials like carbon-filled fluoroelastomers, this sealing process is crucial.
