Nano-PumpTM

Intended for cellular and microbiology applications requiring precision metered fluidic control. Typical applications include cell nucleus extraction and injection, single cell placement and manipulation, sample collecting and many others.
Nano-PumpTM uses poly-phase synchronous DC brushless motors to provide precise positional control. Resolution is typically 640,000 increments per inch (40 nm), yielding single-step displacement of tens of picoliters. The pump’s performance and precision is further enhanced by its unique construction. Fixed lead screw configuration minimizes the number of moving parts, greatly reducing tolerance errors introduced by bearings, slides and pillow blocks found in other syringe pumps. Its rigid construction also minimizes positional error due to chassis deformation. Intelligent pump control is provided by The Motion Group’s MMC motion control/driver system. Features include adjustable torque (over-pressure protection), optical Super-Homing, slip detection and adjustable over-travel safety limits. Other pump control features include ramped acceleration/deceleration (no foaming) and general-purpose I/O functions for valves, indicators, switches and sensors. On-board non-volatile program memory allows the pump to be used for stand-alone repetitive tasks. The controller also interfaces with any computer for interactive real-time tasks (when interfaced with popular control/data acquisition software including LabViewTM) or user-interactive tasks under keyboard control. Multiple units can be networked together for coordinated control.
