Figure 3From: A portable extensional rheometer for measuring the viscoelasticity of pitcher plant and other sticky liquids in the field Comparison of filament thinning behaviour for silicone oil. Filament diameters decreased linearly as expected for a Newtonian liquid. Smaller initial gap sizes yielded a better linear fit. Data sets obtained with Seymour (S, open symbols) and Trimaster (T, solid symbols) devices showed strong agreement. Data are decimated for clarity.Back to article page
