Figure 1From: A portable extensional rheometer for measuring the viscoelasticity of pitcher plant and other sticky liquids in the field Schematic of CaBERâ„¢ operation. ( a ) standard mode, platens move equal distance apart. Initial gap g 0, final gap g f. ( b ) Seymour operation, only upper platen moves. ( c ) Example of N. maxima filament shortly before breakup, g 0 = 0.4Â mm. Time set to zero when platens stop moving, (ii); filament width measured (iii) until break up at t F, (iv).Back to article page
