Adapters for pipettes calibration

 

Pipette calibration adapters are intended for calibration and verification of piston pipettes using gravimetric method. Use of the pipette calibration adapter reduces maximum capacity of the balance by the mass of the weighing vessel. The table presents the minimum reguirements in accordance with ISO 8655 standard. It also enables to select suitable adapter for pipette calibration and respective balance version.

¹ For practical purposes, the nominal volume may be used to choose the balance. [Reference: ISO8655-6:2002, pg. 2]
If the standard uncertainty of measurement of the balance is known (e.g. from the balance calibration certificate), it may be used instead of the repeatability and linearity. The standard uncertainty of measurement shall not be more than two to three times the resolution. [Reference: ISO8655-6:2002, pg. 2]
