SY 60 mm Stroke 900 rpm Precision Syringe Pump (CAT#: STEM-AL-2618-ZJF)

This SY model is a programmable syringe-pump module for automated precision liquid movement. It is controlled by an external computer and supports aspiration, transfer, dilution, and dispensing operations. The drive provides a 60 mm rated stroke with both standard and microstep control. A maximum rotational speed of 900 rpm enables rapid plunger actuation within the listed operating range. The pump accepts optional syringes from microliter capacity to several milliliters. The wetted flow path uses PPS or PEEK, FKM, borosilicate glass, and PTFE. RS232, RS485, and CAN interfaces connect the module to embedded control systems. The assembly is intended for fluid-transfer platforms requiring high speed and repeatable sample introduction.
