A syringe pump designed for precise dosing in the laboratory delivers even the smallest volumes with minimal pulsation, maintains stable operation even with aggressive media, and can be integrated into existing systems. The SyrDos series from HITEC ZANG meets these requirements with flow rates ranging from 0.31 µl/min to 156.25 ml/min and versions capable of withstanding system pressures up to 90 bar.
Whether handling the smallest volumes of liquid, continuous flow, or sensitive substances—our SyrDos syringe pumps offer the highest level of dosing accuracy and reliability. Thanks to their robust stainless steel construction, they are also ideally suited for demanding processes. The SyrDos CKP is also available as a high-pressure syringe pump for applications up to 90 bar—ideal when high system pressures make precise dosing difficult.
Whether in conjunction with an Autosampler, pipetting robot or as a dispenser - the SyrDos adapts to a wide range of applications:
With various valve materials (PTFE, AL₂O₃, PCTFE, PPS) and the option of working with autosamplers or pipetting robots, the SyrDos is perfectly suited for laboratory automation. For processes involving high back pressure—such as in high-pressure synthesis or when handling viscous media—the SyrDos CKP 90 bar is a powerful high-pressure syringe pump. The SyrDos can be easily controlled via either RS-232 or an analog input.
