METHOD OF SUCKING LIQUID

摘要

Object: to reduce the length of time for suction of red corpuscles as specimens of highly viscous liquid. Constitution: when suction of red corpuscles by the use of a nozzle tip is intended, suction is started with the piston retracted to the fullest extent so as to provide a maximum force of suction and, when pressure in the suction system reaches a fixed value alpha , the piston is restored to a point exhibiting a target amount of suction so that the target suction amount is finally attained. Suction speed can be expedited thanks to the suction force of the pump used to the largest allowable capability.
