Alternatively, the contents with the syringe may be discharged into a dry, tared beaker, the volume, in mL, getting calculated as the load, in g, of Injection taken divided by its density. The contents of up to five 1- or 2-mL containers may be pooled with the measurement, provided that a separate dry syringe assembly is used for each container.
