The Perimatic Premier Peristaltic Pump Dispenser is designed for rapid but controlled dose filling of a variety of containers without splashing or frothing. The Perimatic Premier is a heavy duty, microprocessor controlled precision dispensing pump. The Premier achieves its high performance due to its precision rotor and pinch valve design. The Perimatic Premier is particularly suited to media dispensing as its 'stand-by' mode ensures constant recirculation of the reservoir contents thereby keeping the media in suspension when not actively dispensing. The Perimatic Premier can be interfaced with an X-Y module for sequenced filling of multiple containers. See Perimatic XY module (P8563).
