CSI-191 (Blaxial Rotator )
The CSI Biaxial Rotator offers the means for supporting test samples inside an oven, for estimating their resistance to accelerated aging by heat in the presence of air.

The CSI-191 Biaxial Rotator gets its name from the dual axis rotation that simultaneously induces on the test samples mounted on its perimeter bars.

Up to 40 specimens may be tested at once.
The rotor assembly requires a minimum inside clearance dimension of 14 x 14 x 14. Special sized and larger capacities are also available.
