Abstract:
1. A syringe pump adapted to receive a syringe of the kind having a plunger movable along a barrel, the pump comprising: a syringe driving mechanism including a motor, at least one drive shaft, a drive block, and a manual control switch; a logic control circuit operable to control the syringe driving mechanism; a barrel clamp adapted to secure the barrel of the syringe; and at least one data input jack adapted to receive a plug-in probe operable to measure a physical property of the reaction mixture, the at least one drive shaft being externally screw-threaded and connected at one end thereof to the motor so that, in use, the motor can rotate the at least one drive shaft about its axis, the drive block being driveably mounted on the at least one drive shaft in engagement with the external screw-thread thereof and operable to actuate the plunger of the syringe such that the plunger is moved along the barrel of the syringe at a predetermined rate, the at least one jack operable to relay input signals generated by the plug-in probe to the logic control circuit, the logic control circuit operable to process the input signals and adjust the rate according to the input signals, the manual control switch adapted to override the logic control circuit and allow manual actuation of the plunger, wherein the syringe pump can control the addition of a chemical reagent to a chemical reaction mixture.
