Abstract: Device can include an array of stators placed in a carousel which can hold the stators in the array apart from one another while precisely cooled by a suitable source. For example, the device can be provided with cooling in conjunction with an instrument having a highly circulated, cold liquid bath for temperature control such as by insertion of the stators in the carousel through housing of a versatile sensitive rotating viscometer instrument into its bath. The sample carousel has a lower base containing a plurality of stator accommodating orifices in a first array, and an upper base connected to the lower base. The upper base can have a plurality of rotor control pin accommodating orifices in a second array, and the upper base is mounted to the lower base such that the second array of orifices in the upper base is disposed in registry with the first array of orifices in the lower base.
