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. A rotor control pin serving several functions can be mounted in one of the rotor control pin accommodating orifices, which can be moved into controlling contact with a rotor inserted in a stator, and a stator can be mounted in one of the stator accommodating orifices. The first array is such that, when a plurality of stators are mounted in the stator accommodating orifices, one for each of the orifices in the first array, and the carousel is positioned in a temperature control bath having a temperature control fluid, the fluid can be circulated between any two of the mounted stators among the stators mounted in the complete array. The stator can be of a plurality of pieces, for ease of operation and cleaning, with a rotor guiding needle on a bottom cap, and the rotor can have a concave part on its bottom, for accepting the needle and a lateral rotor control part on its top. Low temperature testing of oils can be carried out with high accuracy, precision and responsiveness.
