Abstract

A blood or body fluid collection tube (20) moulded in polyolefin to be open at one end and the interior surface of the tube is flamed treated to at least two-thirds of its depth from the open end. The flaming of the interior surface of the tube is carried out by use of a burner (22 - 25) configured to define in use closely spaced tiered rings of flame that engage the interior of the tube. An apparatus for flame treating blood or body fluid collection tubes moulded in a polyolefin comprises a carriage (13) arranged to support a plurality of tubes (20) in an array with the axis of the tubes extending vertically, a burner assembly (12) including a plurality of burners (22 - 25) each having a burner head of diameter to fit within the tubes (20) and means to cause relative displacement of the burner assembly and the carriage to introduce the head of the burners into the tubes to ensure direct flame contact with the interior surface of the tubes. <IMAGE>
