  • Hot plate with stainless steel top
    Patent number: 7326885
    Abstract: A hotplate with a stainless steel top plate to support a vessel. The stainless steel top plate has an upper surface with a substantially centrally located depression having a depth and area generally sufficient to absorb upward crowning of the top plate when heated. A heating unit is in a heat transfer relation with the stainless steel top plate, and a base unit is connected to the heating plate assembly; however, the base unit is not fastened directly to the stainless steel top plate, so that the stainless steel top plate can expand more uniformly when heated.

    Assignee: Barnstead/Thermolyne Corporation
