How is the calibration on syringe pumps verified?

All syringe pumps that we build go through a ‘fast’ calibration verification test as part of our quality control process before new units are shipped.  If required when ordering a new pump or if ordered during a calibration return we offer a calibration certificate which tests the pumps at several flow rates.

The procedure:

We measure flow accuracy the same way as with all of our pumps: we set the pump to run at a particular flow rate, and then we use a "Pump Scope" to measure the instantaneous position of the pusher block at a set frequency. From that data (and the set syringe diameter), we calculate a flow rate. We average that over the course of the entire lead screw and compare that to the flow rate set on the pump. This gives us the flow rate accuracy. We also use this instantaneous position  data to calculate a Residual Standard Deviation, which gives us a measure of the pulsatility of the pump.

To request a Return for Calibration please submit a return request.  This is a NIST traceable calibration.
