Dual-Channel Syringe Pump EPP-2D, 0.5 µL-100 mL (CAT#: STEM-AL-5580-ZJF)

The EPP-2D is a laboratory dual-channel precision syringe pump designed for delivering two independently controlled electrospinning liquid streams. It uses two separate drive systems so each syringe can operate with its own flow program. Independent, reciprocating, synchronized, and synchronized-convergence modes support coaxial and conjugate electrospinning. A high-resolution touch screen displays channel parameters and operating status. Each channel can select a syringe, store calibration data, and set volume, speed, injection time, withdrawal time, and interval. Linked modes coordinate the two channels for continuous or combined delivery sequences. Target-volume alarms identify completion separately for each channel. The insulating support structure separates the pumps from the high-voltage electrospinning area.
