Abstract

A wick (12) includes a porous molding, which has a plurality of air ducts (26) extending in the vertical direction, a plurality of upper deflection chambers (28), which connect each a first air duct pair (29) of the plurality of air ducts (26) to one another, and a plurality of lower deflection chambers (30), which connect each a second air duct pair (31) of the plurality of air ducts (26) to one another. The two air ducts (26) of the second air duct pairs (31) are each associated with different first air duct pairs (29). An anesthetic evaporator (10) includes a housing (14, 16), which receives the wick (12), so that the vertical air ducts (26) and the upper and lower deflection chambers (28, 30) form an air flow duct between the air inlet (22) and the air outlet (24).
