More than 530 life-science researchers told us how much time they spend each day using a pipette; the types of pipetting errors they encounter; and the reasons for and factors that would influence their next pipette purchase. Updated (08.

Then measure the relative standard deviation in the dispensed masses by calculating the standard deviation and expressing it as a percentage of the average. This is your pipetting error. Repeat this for several different volumes using each of your pipettes and you'll get a pretty good idea of your overall pipetting accuracy.

Understanding pipette failure and preventing recurrence may be the most cost effective way to reduce sources of error while improving quality and compliance.

Pipette. • a 25 cm3 pipette has a maximum error of 0.06 cm3. • like all volumetric equipment it must be used properly. Balances a two-decimal place balance may a three-decimal place balance may have a maximum error of 0.005 g have a maximum error of 0.0005 g. The significance of the maximum error in a measurement.

Understanding pipette failure and preventing recurrence may be the most cost effective way to reduce sources of error while improving quality and compliance.

The quality of the dispensing results of pipettes is defined by two error concepts: • random error and. • systematic error. The Eppendorf Reference 2 specifications for these errors are listed in the user manual and the catalogue. Content. First this paper will explain the two concepts. • random error and. • systematic error.
