The 41th SMIIC MC Training within the SMIIC MC Work Plan 2024 – 2026 V3 was the The Training on Gravimetric calibration of micro-pipettes held on the 10 August 2026 virtually, technically hosted by SMIIC General Secretariat. 33 experts participated in the training.
The training was hosted by NMI: Emirates Metrology Institue (EMI)
General Description: The training covers information on micro-pipettes calibration using gravimetric method and ISO 20461 2023.
Objective, expected outcome: This training course aims to provide general information on how to calibrate micro-pipettes.
Who should attend: The course is suitable for calibration and testing laboratory technical staff working in the field of piston operated volumetric instrument calibration as well as for users, for example in a medical laboratory environment.
