Maintenance
In order to ensure proper functioning, the Transferpette® S -8/-12 should
be serviced at regular intervals and cleaned as necessary.
What must be checked?
a. Check the pipette shafts, pistons and seals for damage and contami-
nation.
b. Check the device for leaks. We recommend using BRAND's leak detec-
tor, the BRAND PLT unit. As an alternative to this, aspirate a sample
and hold the device vertically for approx. 10 s. If drops form on the
pipette tips, refer to "Troubleshooting" Troubleshooting, p. 66 .
