The Atlas Syringe Pump XL from chemistry automation product supplier Syrris, based in Royston, Hertfordshire, UK, is a volumetric dosing and/or sampling system consisting of two syringes, with up to six port valves. With a flow rate of 5µl/min up to 100ml/min, it can be configured either into two refilling flows or one continuous flow, providing reaction sampling, advanced pH control, and temperature-dependent dosing.
Each syringe can aspirate or dispense independently from any valve port, allowing dosing of one reagent to many reactors or many reagents to one reactor. In addition, the Atlas Autosampler Module can be connected directly to one syringe, where it can aspirate up to six samples from the reactor at user-defined intervals. This enables automated dosing from one syringe, while taking six samples from the other. Alternatively, an Autosampler module can be attached to both syringes, enabling 12 samples to be taken.
The Syringe Pump XL can be operated as a stand-alone system, or connected to a Reactor Master (for automation of jacketed reactor systems), an Atlas Base, or controlled by a PC. It can also be connected to an Atlas pH meter and automatically dose acid from one syringe or base from the other to control pH to a user-defined value. In addition, if temperature sensors are attached to the pump, it will automatically pause if the reaction temperature exceeds a user-defined maximum.
