ANR101/CuBe/RES+/ULT/HV - Rotator (360° endless)

rotator with vertical rotation axis

This rotator enables precise rotation of samples around 360° endless in both directions. It includes a 2 mm aperture for routing wiring to the sample.
The positioner is designed for temperatures between mK..373 K and pressures down to 1 E-8 mbar.
For ultra low temperatures in the mK range, a body of beryllium copper is optimal for measurements that are sensitive to small magnetic fields, as titanium can superconduct and expel magentic flux to change the sample environment.
