NORDTEST TR 626 In-house calibration and control of piston operated pipettes

This Nordtest technical report presents three procedures for piston operated volumetric apparatus

used in routine laboratories:

1) in-house calibration;

2) verification of specification; and

3) routine check.

Detailed guidance is presented for pipettes for volumes from 10 μL to 10 mL but the procedures

presented here are also applicable to burettes, dilutors, dispensers and manually operated

laboratory syringes.
