An apparatus for preparing a sample of liquid for examination and analysis. The apparatus includes a tube closed at one end and open at the other, and a pipette dimensioned for insertion into the tube.

Protruding from the sealing surface is a rib which is aligned along the longitudinal axes of the pipette and which engages a portion of the inside wall of the tube to maintain the pipette in the tube.
