You don’t have to recalibrate it to
change flow rates, or after cleaning, or for use after a long idle period. You don’t have to replace peristaltic tubing or worry about corrosion of metal parts. The new ISCO Model 310 Metering Pump has a Teflon diaphragm driven by a solid state servo mechanism. Exact flow rates are read directly from dials on the face of the pump without referring to calibration tables. Accuracy and reproducibility are maintained at flow rates from 1.5 to 2,500 ml/hr at presto 50 psi. All parts consures tacting the pumped liquid are constructed of Teflon, Kel-F, glass, or similar chemically resistant materials.
