Needles
The needles need to be replaced regularly (i.e. at least
after every 6 months) to reduce the risk of clogging
by particles of the septa or when they are bent. To
do so, remove the covers a and b. Unscrew the
needles with the wrench P/N 053204 and pull them
out from the bottom. Needles are available as sets of
12, P/N 053675. Clogged needles can be cleaned with
thin wire.
NOTE
Make sure that the sloped sides of the two needles of
one position always point away from each other.
7.2.4
Septum

lines, replace the septa of the collection vials regularly,
i.e. at least after every 5 runs.
