Pipette check to standard DIN

In this application note, Sartorius provides information on how to ensure pipettes meet the required ISO certification. According to Standard DIN EN ISO 8655-2 volumetric measuring instruments such as piston pipettes must be checked at regular intervals, and at least once per year. Shorter time intervals may be specified by the users depending upon the frequency of use, number of users, aggressive nature of the pipetted liquids and the acceptable maximum permissible errors established by the user.
