Maintenance

After maintenance work, perform a leak test to ascertain correct functioning of
PIPETBOY acu 2: liquid should not leak out of a filled pipette before the dispensing button
is pressed.
5.1 Cleaning and servicing
PIPETBOY acu 2 can be cleaned with a cloth moistened with soapy water or with a 70 %
ethanol.
Disassembly of the nose piece:
It is recommended to change the hydrophobic filter (7d) every three months. Should the
filter get wetted or soiled, it has to be changed immediately. The filter must be oriented
with the blue (0.45 µl) / red (0.2 µl) side facing upwards towards PIPETBOY acu 2.
Annual inspection: If you operate the battery beyond the recommended 3 year period,
visually check the battery for signs of damage, e.g. discoloration, unexpected stains,
shrinking of the tube wrapping.
5.2 Decontamination
The nose piece housing (7b, 7f), the pipette mount (7e) and the filter rubber (7c) can be
autoclaved at 121 °C, 1 bar overpressure for 20 minutes. Silicone may become brittle after
extensive autoclaving. Replace the pipette mount and filter rubber if they are damaged.
If the housing of the PIPETBOY acu 2 have been in contact with biohazardous material,
it must be decontaminated in accordance to good laboratory practice. Do not spray directly
on the instrument but use a lint-free cloth, lightly soaked with a disinfectant and wipe dry
directly after decontamination. Never use acetone or other solvents! Follow the
instructions provided by the disinfectant manufacturer.
The device may be decontaminated with H
minutes.
