ABSTRACT:
Apparatus and method for handling liquid under conditions of weightlessness or near weightlessness includes a small tube being open at one end and closed at the other end except for a passage; normally the open end sits on an elastic nonwetting seal; the tube is moved towards and away from that seal; a plunger on a rod is movably disposed within the tube, and a liquid is kept in the space between the plunger and the open end; the rod is provided with two adjustable, spaced apart stops; and a stationary abutment limits plunger movement to range given by spacing between the stops, so that following evaporation of liquid of a drop that has formed on lift off of the tube, only the residual drop is sucked back into the tube without formation of bubbles.
