Although this pump can be calibrated, calibration does not make it accurate. Some heads may not match, for example I have one that is below 20% of the calibrated value. Calibrated to 50ml for example and pumps 40. The other 3 heads only pump 45-44 out of the requested 50. The pump is cheap, convenient and works, although I don't know how reliable it is. Just make sure you calibrate it carefully before using it to see which heads are faulty. Use suitable measuring devices for this.
