Calibration Guidelines
ISO 9001 and GLP-guidelines require regular examinations of your
volumetric instruments. We recommend checking the volume every
3-12 months. The interval depends on the specific requirements of the
instrument. For instruments frequently used or in use with aggressive
media, the interval should be shorter.
