Abstract
A device is described for expressing liquid absorbed by the tip of a medical swab. The device comprises a barrel and a plunger slidable within the barrel for squeezing the tip of the swab. Liquid is discharged through a flow channel in the container or in the swab shaft. The device is useful particularly to recover small volumes of swab-absorbed liquid where necessary e.g. to carry out clinical essays.
