Which is a correct laboratory technique? * The minimum number of centrifuge tubes in a centrifuge machine during its operation is one. An open flame is the heat source for heating or evaporating flammable liquids. Never place reagents directly onto the weighing pan of a balance, always use weighing paper, a beaker, or some other container. Water or glycerol should not be applied to the glass tubing and to the hole in the rubber stopper before inserting the glass tubing.
