The characterization of the physical properties of biomaterials such as biological soft and connective tissues inherently requires the testing of such materials within a simulated body fluid environment. Because both of the detachable drums are cantilevered and suspended from the SER2 base chassis, the SER2 models that are configured for use on controlled stress/strain rotational rheometers such as the SER2-P, SER2-G, SER2-M, and SER2-T are capable of fluid immersion testing. The drums of said SER2 models can be raised from and lowered into a controlled temperature fluid environment contained within a jacketed beaker or other such fluid containment vessel for the purposes of characterizing the physical properties of natural or synthetic biomaterials. In this manner, sample specimens can be easily loaded and unloaded from the windup drums while the SER2 is completely raised from the fluid surface. The image below depicts a model SER2-P hosted on an Anton Paar MCR 501 rotational rheometer suspended above a controlled temperature fluid environment contained within a glass jacketed beaker.

The following videos depict the tensile testing of a ring-shaped cross-sectional blood vessel specimen dissected from a porcine right sublcavian artery as illustrated in the above diagram and photo. The ring specimens were simply looped around the securing clamps before clamp insertion into the windup drums thereby defining a ring tensile test which is commonly used for evaluating hoop stresses in pipes and other such pressure conduits. Note as well that all of the following videos depict rough textured SER2-DR drums that were used in order to assist in sample gripping during the stretching process within the fluid environment.

Note that for all of the SER videoclips depicted below, the sample deformation remains in a fixed plane and is ALWAYS clearly and easily accessible for deformation visualization.

Also note how in all cases only the drums of the SER2 need to be immersed within the fluid environment.
