Drying time[s]In order to dry the capillary viscometer after rinsing with solvents,the running time of the suction pump is extended after the suctioning of the last solvent fill by the set drying time.This will suction airflow through the viscometer,which makes the solvents evaporate.The drying time must be selected to be long enough for the solvent residue to evaporate completely.The drying time depends on the volatility of the solvent and the viscometer used(suction via suction pipe or suction hose in the fill pipe).
