The Atlas Syringe Pump XL, from Syrris, is a versatile volumetric dosing and/or sampling system consisting of two syringes, with up to six port valves. With a wide flow rate range of 5 µl/min up to 100 ml/min, it can be configured either into two refilling flows or one continuous flow, providing reaction sampling, advanced pH control, and temperature-dependent dosing, for flexibility. It also offers high chemical resistance.
Each syringe can aspirate or dispense independently from any valve port, allowing dosing of one reagent to many reactors or many regents to one reactor. 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 twelve samples to be taken. This increased operational flexibility makes it a valuable tool for a wide range of automated chemistry applications.
The Atlas 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 be connected to an Atlas pH meter and automatically dose acid from one syringe or base from the other to automatically control pH to a user defined value. Also, for safety, by attaching temperature sensors the pump will automatically pause (in a range of dispensing modes) if the reaction temperature exceeds a user defined maximum.
