Abstract: A continuous flow reactor, a method of performing a continuous flow reaction, and a method of controlling a moveable wall of a reaction chamber of a continuous flow reactor. The reactor comprising: an inlet; an outlet; and a reaction chamber, between the inlet and the outlet and providing a flow path therebetween, the reaction chamber having a moveable wall; the reactor further comprising: a pressure sensor configured to monitor a fluid pressure in the continuous flow reactor; and a controller, operable to adjust the position of the moveable wall, and thereby change a volume of the reaction chamber, based on the monitored fluid pressure.

Abstract: Provided is a pump and a method of controlling a pump. The pump and method are particularly for use in dispensing reagents, for example in flow chemistry, and more particularly on a laboratory scale. The pump aims to provide a substantially constant output flow of fluid. The pump comprises: a motor; a peristaltic pump having a rotor driven by the motor; a pressure sensor monitoring the pressure of the pumped fluid downstream of the pump; and a control unit which controls the motor by adjusting the standard operating speed of the motor according to the pressure detected by the pressure sensor, such that the pump operates continuously at a rate set by an operator. Embodiments of the pump make use of lookup tables to determine a desired position of the pump rotor at each point in the cycle with the entry point into the lookup table being determined by the feedback from the pressure sensor.
