Peristaltic pump PFU is a standalone, single channel high precise peristaltic pump filling system.  It can be used independently as a small benchtop filling system or integrated into semi-automatic or fully automated precise filling system for bio-pharmaceutical or precise liquid handling applications.   It features small footprint, compact structure and low flow pulsation.  The anodized aluminum housing is good for preventing corrosion.   The filling volume can be generated as low as 30uL with inaccuracy of +/-1%.  The PFU includes the 7inch touchscreen controller, which can control up to 32 channels.
