Abstract
In measuring dynamic viscoelasticity, a problem that a viscous fluid sample such as polymer melt index, thermosetting resin, adhesive, or paint cannot be measured for dynamic viscoelasticity can be solved. Disclosed is a sample container 1 used to measure dynamic viscoelasticity according to temperature changes occurring when heating or cooling a sample. The sample container 1 includes a lower-end-closed sample cup with an opening at an upper end, and an insertion jig 5 having a cross section smaller in area than the opening of the sample cup 2, being insertable into the sample cup 2 through the opening, and being capable of transferring vibration to a sample contained in the sample cup 2.
Claims5
A dynamic mechanical analyzer for measurement of dynamic viscoelasticity according to temperature changes caused when heating or cooling a sample comprising:
- a sample cup with a lower-end-closed tubular shape with an opening at an upper end;
- an insertion jig having a cross section smaller in area than the opening of the sample cup, being insertable into the sample cup through the opening, and being capable of transferring vibration to the sample contained in the sample cup;
- a temperature varying unit configured to heat or cool the sample cup, the dynamic mechanical analyzer having a function of measuring the dynamic viscoelasticity;
- and
- a sample cup holding rod protruding downward from a lower surface of the sample cup.
