System and method for titrating liquids

A system for titrating liquids, the system comprising:

• a syringe (1) comprising a plunger (9) and a holding device;
• a metering equipment (13) comprising:
• an additional holding device for holding the syringe (1) on the holding device;
• a driving device (18) having a motor (19), which is detachably coupled with the plunger (9) of the syringe (1) when the same is held by the additional holding device;
• an operating device (23) for operating the metering equipment (13);
• and
• a control device (22), connected with the operating device (23) and the driving device (18), configured to:
• control a movement of the plunger (9) for the delivery of at least one first amount of liquid in a first delivery phase,
• wherein the control device is further configured to control the movement of the plunger in the first delivery phase when an operating element of the operating device is actuated, and
• configured to control the movement of the plunger (9) for the delivery of at least one defined second amount of liquid in a second delivery phase when triggered by an actuation of the operating device (23) or by reaching the end of the first delivery phase, wherein the at least one defined second amount of liquid is less than the first amount of liquid,
• at least one tag (6, 7) disposed on a flange (5) of the syringe (1), wherein the metering equipment (13) further comprises a reading device (17) for reading the tag (6, 7) of the syringe (1)
• wherein the tag (6, 7) is configured to indicate the nominal volume of the syringe (1),
• wherein the control device (22) is configured to control the movement of the plunger (9), the speed and/or acceleration of the plunger (9) and/or the displacement of the plunger (9) depending on the tag of the syringe (1),
• wherein the control device is configured to control a speed and/or an acceleration of the plunger (9) such that the speed, and/or the acceleration of the plunger of a syringe with a first volume is less than the speed, and/or the acceleration of the plunger of a syringe with a second volume less than the first volume or
• wherein the control device (22) is configured to control a speed and/or an acceleration of the plunger (9) such that the speed, the acceleration of a syringe with a first volume is greater than the speed, and/or the acceleration of the plunger of a syringe with a second volume less than the first volume.
