into the tube fitted with pump-stirrer and thermometer. If
the material is too viscous for volumetric transfer, weigh to the
nearest 0.01 g a quantity of sample corresponding to 10 mL at
room temperature. Place the thermometer in the tube so that the
contraction chamber is below the liquid level and so that the
mercury bulb does not touch the side of the tube. Assemble the
apparatus as shown in Fig. A2.2.
