7.1 Samples and sample vials
Note the following points:
￭ The following types of racks or micro titer plates are supported:
– 12 samples
– 48 samples
– 96 samples (low form, low)
– 96 samples (high form, high)
– 384 samples (low form, low)
￭ Fill the standard vials with a pipette in order to ensure that any air bub-
bles that may appear can escape during filling.
￭ Do not fill sample vessels up to the edge. Doing so would cause the
sample liquid to be pressed into the air needle. This could cause a
cross-contamination of the samples and a contamination of the nee-
dle.
￭ It is important that the sealing caps and septa be air-tight in order to
prevent the formation of air bubbles and the evaporation of volatile
samples.
We recommend the following types of seals:
– For standard micro titer plates (low) sealing tape
– For deep well plates (high): pierceable sealing mats (pre-slit or
made of silicone) or sealing tape
– For vials: thin standard septa; no vials with hard caps which are
not designed for being punctured by an injection needle.
￭ If you use unsealed vials or micro titer plates, the precision of the injec-
tion will not be in accordance with the specifications.
7.2 I/O interface
Caution
The manufacturer assumes no liability for damage which is either
directly or indirectly caused by connections between the 889 IC Sample
Center and devices which do not meet the relevant safety standards.
