Volumetric Die Cutter
The use of constant volume samples means it is possible to achieve greater repeatability in the Rheometric and Viscosity tests.
Undersized samples cause imperfect filling
Oversized samples require longer temperature recovery times at the start of the test.
Gibitre Instruments constant volume die cutter has an exclusive adjustment system that permits different samples to be obtained for:
Moving Die Rheometer
Oscillating Disk Rheometer
A puncher, incorporated in the instrument, permits the central hole to be made in the lower sample for the Mooney viscosity test.
