  • Q:

    Hi, how often should I do the calibration?
    Asked on 10/25/2015 by Ying from Princeton, NJ

    1 answer



      It would depend on how often you use the pump. You should calibrate anytime the application changes to receive optimum accuracy. You should calibrate when the tubing is changed as well. If you see an issue with the accuracy, the pump should be calibrated.

  • Q:


    I used to own the older model of the L/S pump WU-07523-50. My application requires the pump connecting to a timed power outlet. With the old model, when the power is cut and resumed the drive automatically turns back on with the preset speed.

    However, recently when I replace it with this newer model WU-07522-30, the drive will not resume running after the power is cut off and resumed.

    Is there a setting or workaround where I can control the pump with a timed outlet like the older model?

    Asked on 1/15/2015 by Brian from United States

    1 answer



      Power cycling this drive with a timer is not recommended. I would suggest using the internal batch dispensing options to set the delay between cycles.

      Best Uses

        We are overall satisfied with this product. Although a bit expensive for what it is, in the long run it is worth it and is good value. It is so much easier to use this device then to manually pipet large amounts of tubes. The interface is simple and easy to use. The only down side is that the calibration process takes a bit too long, and we often have to estimate then measure ourselves. But for aliquoting the same volume it seems to be very accurate.
