| Zusammenfassung: | According to the new version of ISO 8655-6, a tip change must be performed when calibrating piston-operated pipettes with air cushion. The requirements for tip replacement are given in chapter 8.3.2 of ISO 8655-6. The necessity is explained by the fact that the tip change would reveal the use of damaged or incorrectly manufactured tips. The requirement also applies to direct displacement piston-operated pipettes. To verify the influence of the tip change, a member of the DKD has carried out repeated investigations. |
