Cleaning
The most important cleaning procedure for this instrument is to rinse the wash
system before the instrument is left to stand or switched off at the end of each
day.
Caution
If the manifold is not rinsed, the needles will become blocked.
This will result in the manifold either needing expensive repairs
or it could become completely ruined.
The manifold can be cleaned using:
•
The supplied cleaning needles (accessory box)
Carefully push the cleaning needles into the aspirating and dispensing
needles.
The small cleaning needle is for the dispensing needles and the large
cleaning needle is for the aspirating needles.
Rinse the manifold block with distilled water to ensure that all particles have
been removed.
•
A gentle ultrasonic bath of warm distilled water for 15 minutes.
•
Autoclaving
(max. 130 °C , max. five times)
Note:
Autoclaving is only intended for use with a manifold that is not fitted with
the Fill Verification option. Manifolds with the Fill Verification option
should only be cleaned in an ultrasonic bath. If additional cleaning is
required, use a small brush. Do not use autoclaving.
