The 313D aseptic dental irrigation pumphead is ideal for dental applications requiring frequent tube changes, and flow rates from 0.25 to 3,000 ml/min. The fluid being pumped is contained completely in the USP Class VI approved tubing, so cleaning the pump is as simple as replacing a tube. It has been designed so that tube replacement is intuitive and foolproof for operators of a dental device. The pumphead opens wide, and then clamps and stretches the tube as it closes, putting the tube in the position to deliver optimum pumping performance, every time. There is no need for extensive training, tools, or adjustments when using the 313D.
