2-4 Product Overview
The 7900HT instrument contains the hardware used for thermal cycling and detection
of fluorescent chemistries (see page 2-2). The figure below illustrates the major
subcomponents of the instrument described in further detail below.
! CAUTION Do not remove the cover to the ABI PRISM 7900HT Sequence Detection
System. Only a qualified Applied Biosystems service engineer may repair or adjust the internal
components of the 7900HT instrument. Failure to comply can result in serious injury and/or
damage to the instrument.
! WARNING PHYSICAL HAZARD. Keep hands and loose clothing away from the instrument
tray and door at all times during instrument operation. The 7900HT instrument contains several
internal components that can cause serious physical injury.
The 7900HT instrument features an automated plate handling system to provide easy
loading and removal of plates from the instrument. In combination with the automation
module, the plate handling system allows unattended operation of the instrument.
!
WARNING PHYSICAL INJURY HAZARD. Hot Surface. Use care when working around this
area to avoid being burned by hot components.
The 7900HT instrument features a heated clamp that provides optimal heat transfer
and uniform heating during thermal cycling. When the instrument tray loads a plate,
the clamp applies a downward pressure of 70 lbs (31.8 kg) onto the consumable.
During the run, the clamp maintains a constant temperature of 105 °C (±3°C) to
prevent condensation within the consumable wells.
