description	There is disclosed apparatus in which an aspirating and dispensing tip (10) is provided with liquid wherein residual liquid may be left as a sheath on the exterior surface of the tip (10) after aspiration. The apparatus includes means (40, 44) exterior of the dispensing tip (10) for separating the sheath into at least two parts without detaching residual liquid physically from the exterior surface, the liquid part closest to said aperture being separated from the liquid part next above along the axis (11 ) of the tip (10) by a dry annular portion of the exterior surface having a suitable width. Such separating means (40. 44) is spaced away from the tip (10) a distance (Z) effective to prevent contact of the separating means 140, 44) with either the tip (10) or the liquid of the sheath.
