Solid Aluminum Block Units are designed to be used in conjunction with either coolers, chillers, and ice buckets to keep'em cold or on a hot plate to keep'em hot while working on the bench.
Because aluminum is such a great temperature conductor, these units will 'cold-down' or 'heat-up' quickly and evenly assuring a constant temperature throughout the block. Further, the cavities (or chambers) in each unit are engineered to 'surround' the majority of the surface area of the respective tube, tubestrip, or plate to keep them at a constant and even temperature throughout.
