Volume Accuracy Failure - 850-DS Dissolution Sampling

During volume accuracy test of our 850-DS Dissolution Sampling, the difference of the sample volume for position #2 for 10mL was higher than 0.5mL, being that specification is lower than 0.25mL.

How can we calibrate the equipment to sample the right volume?

We performed the full range volume dispense (in the calibration screen), but we are not sure how to use the data to do the equipment calibration.

Could you help us, please?

  • Hi everyone,

    I would like to thank for your help and give you a feedback of the actions taken.

    We performed the calibration, but it was not enough and we needed to replace the syringe for this position.

    After replacement, we performed the calibration procedure and volume accuracy is perfect now.

    Thank so much for you help.
