CALIBRATION OF MASS STANDARDS
Calibration of mass standards refers to determining
standard’s mass with expanded uncertainty and issuing
certificate of calibration. In addition, it is possible to carry
out adjustment of a mass standard (determine its
parameters within the limits of maximal permissible errors
specific for its accuracy class) and issue conformity
certificate with requirements as specified by the client.

CALIBRATION OF PIPETTES
Calibration of piston pipettes covers determining indication error of a
pipette in a tested volume with determining the expanded uncertainty
and issuing certificate of calibration.
Calibration is carried out using gravimetric method, in accordance
with standard ISO 8655-6. Additionally, a certificate of calibration
can specify calculation of errors and their results as listed in the
standard ISO 8655:
- Systematic error e
s
– determined in [µl] units and in [%]
- Random error – determined as standard deviation S
p
in [µl]
units and CV expressed in [%]
Pipette volume
1µl ≤ V ˂ 10µl
10µl ≤ V ≤ 100µl
100µl ≤ V ≤ 5000µl
