4.5.4 Special beakers
Special beakers are reserved positions in a sample rack. 0 to 8 special
beakers can be defined per rack. They can be placed under the needle
during method processing for particular operations without interrupting
or hindering the sample series run. Special beakers can be used in a
sample sequence for rinsing the needle.
Special beakers are placed under the needle with
'MOVE 1 : spec.1' .
Reserved special beaker positions, that can be individually defined for
each rack, are recognized as such in a sample series and are omitted
during processing of the individual sample beakers.
For the 6.2041.430 sample rack, the two positions 128 and 129 are al-
ready defined as special positions for the 6.1608.080 PE bottles
(300 mL).
Sample method for the use of special beakers
With this method 'PCRinse' , modified from the standard method 'PC' ,
the needle and the tubing leading to the sample loop is rinsed with
rinsing solution during 60 s after each sample. For this method, a
6.1608.080 PE bottle filled with rinsing solution must be set as special
beaker 2 on position 129 of the sample rack.
