3.2.2 Pipettor head
The pipettor head is mounted above the worktable and
moves in the Z direction (i.e., up and down) in order to reach
the samples and reagents on the worktable. The worktable
itself moves in the Y direction (i.e., front to back) in order to
present different samples and reagents under the pipettor
head.
The pipettor head contains 6 high-precision syringe pumps
that are connected to tip adapters that can be attached to
filter-tips. The syringe pumps operate simultaneously to allow
aspiration or dispensing of small volumes of liquid
(50–1000 μl) via the filter-tips.
The pipettor head also contains a magnet whose distance
from the attached filter-tips can be varied. This feature allows
the capture of magnetic particles that are present in the
liquid aspirated into the filter-tips.
Located behind the tip adapters is the piercing unit, a row of
6 metal spikes for puncturing the foil that covers the reagent
cartridges.
