Transferpettor
Testing Instructions (SOP)
May 2009
1. Introduction
The standards DIN EN ISO 8655 describe both the design and the
testing of the piston operated pipette Transferpettor The following
Testing Instructions describe how to apply the ISO standard in
practice.
We recommend a testing of the Transferpettor every 3 - 12 months.
This interval may be adjusted to individual requirements. For
example, when working very frequently or when using aggressive
media, the instrument should be tested more frequently.
These Instructions may also be used as a basis for the supervision
of testing devices to DIN EN ISO 9001, DIN EN ISO 10012 and
DIN EN ISO/IEC 17025.
For the regular examinations required by DIN EN ISO 9001, DIN
EN ISO 10012, DIN EN ISO/IEC 17025 and the GLP Guidelines,
BRAND (see chapter 7) additionally provides a calibration service.
Your instrument will be returned within a few days together with
a test report. For more detailed information, please contact your
labware supplier.

    4. Gravimetric test For Transferpettor with nominal volume > 50 µl 1. Set the nominal volume. ⇒ Enter temperature into Test Record (). 2. Determine temperature of the deionized water for testing. 3. Pre-rinse the cap / capillary once. ⇒ Take in testing liquid once, and release again, the cap/ capillary must be bubble-free.
  • Page 6 Therefore, the testing of pipettes of this size requires a test procedure which largely prevents evaporation. For this purpose, BRAND has specially developed the following test procedure. The weighing vessel used is a disposable micropipette which virtually eliminates evaporation.
  • Page 7 Observe the suggestions under "Troubleshooting" in the Operating Manual. n Calibrate the Transferpettor as described in the Operating Manual (recalibration is only possible with recent models). If these measures are not successful, we recommend to use the BRAND calibration service (see page 11).
