6.1 Cleaning and Decontamination
WARNING
Always turn off power and disconnect the VIAFLO 96/384 from the mains
when carrying out maintenance work.
6.1.1 Base unit
If the external components get soiled, clean them with a lint-free cloth lightly soaked with
mild soap solution in distilled water or with a 70 % dilution of Isopropyl or Ethanol. Never
use acetone or other solvents. Ensure that the guide rails of the base unit are clean,
greasing is not required.
If the surfaces of the VIAFLO 96/384 have been in contact with biohazardous material,
they must be decontaminated in accordance to good laboratory practice. Wipe the clean
surface with a lint-free cloth, lightly soaked with a disinfectant. For example:
• Ethanol 70 %
• Microcide SQ 1:64
• Glutaraldehyde solution 4%
• Virkon solution 1-3%
Follow the instructions provided with the reagents.
6.1.2 Pipetting heads
Remove the pipetting head from the device. Regularly clean the pipetting head surface
and the tip fittings with a moist lint-free cloth lightly soaked in distilled water or Ethanol/
Isopropyl 70 %. Alternatively, just spray Ethanol 70% or Isopropyl 70% on the tip fittings
and let them dry. Do not spray into the tip fittings.
W
ARNING
Spraying Ethanol 70% or Isopropyl 70% on the tip fittings may not be
sufficient to completely decontaminate the pipetting heads because it does
not reach the inner parts. Only gas sterilization or autoclaving inactivates
harmful micro-organisms on the inner parts of the pipetting heads.
6.2 Prolonged period of non-use
Pipetting heads of VIAFLO 96/384 should not be left inside the device if not used for
extended periods (>1 week). Remove the pipetting head from the device and store it
wrapped in a plastic bag in the appropriate casing.
