Porpoise have more experience in twin bore applications than any other company. This experience comes from :-

bullet actually using twin bores 
bullethaving a deep fundamental understanding of the rheology involved
bulletadvanced computer flow simulation.

The Intelligent Rheometer is based on a 100kN twin bore design with 1,200mm/min piston speed. The bore sizes available are 9.5mm, 12mm, 15mm, 19mm and 24mm. The barrel materials available are Nitrided Steel, Stainless Steel, Hastalloy B and Ceramic coated.

Q. Why twin bore ? 
A. Their are a number of very significant advantages in twin bore rheometers over single bore rheometers. Some are :-

bulletEfficiency gain of ~ 3 in running tests ....
...more tests for your money, less time for testing.
bulletGreater certainty in results...
...samples in each bore have the same history.
bulletExtensional viscosity and Shear viscosity in one test...
...convergent flow extensional viscosity.
bullet Degradation of shear and extensional behaviour...
... in one test
