Abstract
Abstract A method of cooling a selected area of a medium employed in electrophoretic separation consists in arranging an elongated porous wick in heat exchanging relationship with the selected area while maintaining another portion of the wick submerged in a liquid coolant, a portion of the wick being exposed to the atmosphere for evaporative cooling.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
80 words
METHOD FOR DIVERTING OF THE HEAT, GENERATED AT ELECTROPHORETICAL SEPARATION, THE ELECTROPHORETICAL SEPARATION BEING PERFORMED IN A MEDIUM, CONTAINED IN A VESSEL OR APPLIED TO A SUPPORT PLATE, CHARACTERIZED IN THAT A COOLING MEDIUM IS EXERTING COOLING EFFECT BY BEING EVAPORATED, PREFERABLY FROM THE SURFACE OF A POROUS WICK, SUSPENDED AT SAID VESSEL AND SUPPORT PLATE RESPECTIVELY, VIA WHICH WICK THE COOLING MEDIUM IN LIQUID PHASE IS SUCKED UP FROM THE CONTAINER IN WHICH PART OF THE WICK IS DIPPING.
Claim 2
Dependent Claim
80 words

Claim 3
Dependent Claim
67 words
Apparatus for cooling a selected area of an electrophoretical separation medium, comprising an elongated wick of porous material, means for maintaining a first portion of said wick in heat exchanging relationship with said selected area of the medium, and means for submerging a second portion of said wick in a body of liquid coolant, a portion of said wick being exposed to the atmosphere for evaporative cooling.
Claim 4
Dependent Claim
67 words
Apparatus for cooling a selected area of an electrophoretical separation medium, comprising an elongated wick of porous material, means for maintaining a first portion of said wick in heat exchanging relationship with said selected area of the medium, and means for submerging a second portion of said wick in a body of liquid coolant, a portion of said wick being exposed to the atmosphere for evaporative cooling.
Claim 5
Dependent Claim
75 words
The invention defined in claim 2, wherein said liquid coolant is contained in a vessel, and said means for maintaining said wick in heat exchanging relationship includes a grating for supporting said first portion of the wick in a horizontal plane above the level of said liquid coolant, at least one end of the wick being submerged in said coolant, the selected portion of said medium being disposed above said first portion of the wick.
Claim 6
Dependent Claim
22 words
The invention defined in claim 3, wherein a plate composed of heat conducting material is disposed between said wick and said medium.
