11.13.  PIPETTES CALIBRATION 

Caution! Function valid for AS R series balances exclusively. 

 

Pipettes calibration function applies to fixed volume pipettes and adjustable volume pipettes. During 
volume testing procedure, the software determines accuracy and repeatability errors.  In case of 
pipettes with adjustable volume, errors for Max, Min and ½ Max volume are estimated. 
All pipettes are tested for adherence to  requirements of PN-EN ISO 8655:2003. During the tests 
dosing repeatability and accuracy are monitored. 
 
In order to ensure the highest accuracy of pipettes calibration process, maintain the following 
ambient conditions at a workstation:  

 

Ambient temperature of a pipette, tips and liquid should be kept between 20°C -  25°C with 
change rate during testing within ± 0.5°C, 

 

Relative humidity 50 - 75%; 

and  

 

Use distilled water for pipettes calibration processes, 

 

Make sure that a pipette, tips and distilled water are thermally stabilized in the room intended 
for weighing operation performance. The reference standard advises that minimum 
acclimatization time for above mentioned is 2 hours. 

 

 

Prior pipettes calibration start, it is necessary to install a dedicated set inside the draft shield. The set 
is not a standard balance equipment. The picture below presents set installation. Evaporation ring 
minimizes measurement errors being a result of evaporation of liquid occurring in course of the 
weighing process. 
 

 

 

Prior to pipettes calibration pour 2/3 of the evaporation ring with distilled water. The set is ready to be 
used after about 1 hour –  it takes this long for humidity  to stabilize. Excess water can be removed 
using automatic pump or an external pipette. 
To minimize any humidity changes inside the chamber and to avoid air draft influence while opening 
the door, dose the liquid from a pipette to an evaporation ring via an opening of a weighing chamber 
lid. 
With thus prepared balance you can start pipettes calibration procedure. 
 

11.13.1. Additional settings of pipettes calibration mode 

Apart from standard settings for this mode (i.e. weighing mode settings) some additional parameters 
have been designed to describe operation of the mode.  
Additional settings list: 

 

VOLUME DETERMINATION

  –  allows to predefine number of tested volumes for a particular 

pipette. For pipettes with fixed volume please set parameter <1>, for pipettes with adjustable 
volume set parameter <2> and <3>. 

 

MEASUR. NO

 – allows to predefine number of measurements for each tested volume. Number 

of measurements ranges from 6 to 20. 

 

AUTOMATIC TARING

 -  allows to turn on function of automatic taring of dosed portion of water 

after confirmation of measurement (value set to <YES>)  

Remember to select correct values of the above options before pipettes calibration procedure is 
performed. The settings should reflect expectations and needs being a result of working environment.
