We purchased some old pipettes that had never been used (essentially brand new, but from 2007 and 2009).
Inside each box is a quality control certificate stating that the pipette was tested in an accredited calibration laboratory.
The question is since some of these certificates are from 2007 and some from 2009 are they still valid, or do I need to send out the pipettes for calibration even through they have never been used?
Thanks
