A device for distilling a fluid, the device comprising: - a first and a second plate; - a frame with opposite outer surfaces being detachably attachable to inner surfaces of the first and second plates and having a shape by which only one chamber is defined by the frame and the inner surfaces, the frame defining: - an inlet for releasing the fluid into the chamber, - a first outlet for releasing waste fluid from the chamber, - a second outlet for releasing distilled fluid from the chamber, and - a separator; wherein the inlet is arranged to allow the fluid which is released into the chamber to flow in a first flow path along the inner surface of the first plate from the inlet towards the first outlet; wherein the second outlet is arranged in flow communication with a second flow path along the inner surface of the second plate to capture fluid which is formed by condensing on the inner surface of the second plate; and wherein the separator is defined by an essentially plane element formed in one piece with the frame and extending from a location between the outlets (106, 107) in a direction towards the inlet and being arranged between the outer surfaces to separate a part of the chamber into a first space in which the first paths ends and a second space in which the second flow path ends; wherein the only one chamber defined between the first and second plates is a combined evaporation and condensation chamber with a lower evaporation surface defined by the inner surface of the first plate, and an upper condensation surface defined by the inner surface of the second plate; wherein the inlet is formed with a gutter shaped groove extending transversely to the first flow path and being shaped to allow fluid entering the device through the inlet to be distributed over a width of the frame before being released onto the first surface, said gutter shaped groove and frame define a monolithic element; wherein a drip nose is provided above the gutter shaped groove, where the drip nose defines a groove opposite the gutter shaped groove, whereby a transversely extending flow channel is defined by the gutter shaped groove and said opposite groove. - a first and a second plate; - a frame with opposite outer surfaces being detachably attachable to inner surfaces of the first and second plates and having a shape by which only one chamber is defined by the frame and the inner surfaces, the frame defining: - an inlet for releasing the fluid into the chamber, - a first outlet for releasing waste fluid from the chamber, - a second outlet for releasing distilled fluid from the chamber, and - a separator; wherein the inlet is arranged to allow the fluid which is released into the chamber to flow in a first flow path along the inner surface of the first plate from the inlet towards the first outlet; wherein the second outlet is arranged in flow communication with a second flow path along the inner surface of the second plate to capture fluid which is formed by condensing on the inner surface of the second plate; and wherein the separator is defined by an essentially plane element formed in one piece with the frame and extending from a location between the outlets (106, 107) in a direction towards the inlet and being arranged between the outer surfaces to separate a part of the chamber into a first space in which the first paths ends and a second space in which the second flow path ends; wherein the only one chamber defined between the first and second plates is a combined evaporation and condensation chamber with a lower evaporation surface defined by the inner surface of the first plate, and an upper condensation surface defined by the inner surface of the second plate; wherein the inlet is formed with a gutter shaped groove extending transversely to the first flow path and being shaped to allow fluid entering the device through the inlet to be distributed over a width of the frame before being released onto the first surface, said gutter shaped groove and frame define a monolithic element; wherein a drip nose is provided above the gutter shaped groove, where the drip nose defines a groove opposite the gutter shaped groove, whereby a transversely extending flow channel is defined by the gutter shaped groove and said opposite groove.
