VWR Modular Heating Blocks Solid. Non-stick coating on the interior of the heating blocks permits the use of water without boiling. The non-reactive material in the heating blocks (glass porcelain or nickel) permits the use of water without boiling. The heating blocks stabilize temperature over a wide range by allowing water to circulate throughout the block. Unaffected by water these products can be immersed in water baths thereby reducing the need for electrical currents. Using the immersion heaters also stabilizes temperature over a broad range.
