A wick assembly (1) for use in e.g. an anaesthetic vaporizer (not shown) comprises layer (2) of absorbent wick material, e.g. a metallic wire cloth, secured to an impermeable backing sheet (3) e.g. of stainless steel. The wick material (2) and backing sheet (3) are rolled into a spiral configuration and thus define a spiral flow passage for gas to be vaporized. Fastening means are provided to hold the wick material (2) and sheet (3) in the spiral configuration whereby the assembly forms a self-contained unit adapted to be detachably mounted in a vaporizer.

A wick assembly for a vaporizer, such assembly comprising an absorbent wick material provided with a substantially impermeable backing sheet, the wick material and the backing sheet being disposed in a substantially spiral configuration so as to define a substantially spiral flow passage extending through the assembly, the spiral configuration being formed by mating together the wick material and backing sheet in face to face relationship and rolling them into the spiral configuration with the wick material disposed on an outwardly facing convex side of the backing sheet, so that in a rolled assembly the wick material is stretched into intimate contact with the backing sheet, fastening means being provided to hold said wick material and backing sheet in such spiral configuration, and means for detachably mounting the assembly in a vaporizer.
