Figure 2From: A portable extensional rheometer for measuring the viscoelasticity of pitcher plant and other sticky liquids in the field Comparison of linear (Hencky) strain between portable (Seymour) and laboratory (Trimaster) devices. The initial gap, g 0, was 0.7 mm and reaches a final gap of 1.9 mm. Both devices produced similar separation speed. Seymour produced less overshoot and higher damping than the Trimaster.Back to article page
