The aim of this contribution is to present invariance of elongational viscosity measured with respect to a rectangular shape and thickness of LDPE samples using an SER Universal Testing Platform fixed in Anton Paar MCR 501 host system. The width of the samples was changed in the range 2.1-12.7 mm and thickness altered within 0.3÷1 mm. The measurements when a thickness attained 0.1 mm are also presented. There are further compared measurements with and without the clamps.
