16 - Device Commands
Commands for the Hettich Centrifuge
16.5.2 Hettich Centrifuge - Open Command
The Open command opens the door of the centrifuge.
This command has no execution parameters or objects, pre-actions or postactions.
16.5.3 Hettich Centrifuge - Close Command
The Close command closes the door of the centrifuge.
This command has no execution parameters or objects, pre-actions or postactions.
16.5.4 Hettich Centrifuge - ExecuteN Command
The ExecuteN command carries out centrifuging with N rotor positions of the
device occupied by labware (N = 1, 2, 3 or 4). After the microplates have been
placed into the device and the door closed, the centrifuge will start rotating with
the specified parameters.
To avoid mechanical imbalance, microplates must be put into the centrifuge in
pairs. For example, if you only want to centrifuge one microplate (Execute1
command), you must put a second microplate in the opposite rotor position of the
centrifuge. You can do this by specifying appropriate RoMa MoveObject
commands in the custom pre-actions and post-actions. However, if you always
want to centrifuge just one microplate, it is easier and more efficient to put a
second microplate into the centrifuge by hand.
The Execute1 command puts the microplate in rotor position 1 – to avoid
imbalance you must put another microplate in rotor position 3. The Execute2
command puts microplates in rotor positions 1 and 3 (a balancing microplate is
not necessary). The Execute3 command puts microplates in rotor positions 1, 2
and 3 – to avoid imbalance you must put another microplate in rotor position 4.
The Execute4 command puts microplates in rotor positions 1, 2, 3 and 4 (a
balancing microplate is not necessary).
Execution parameters
You are prompted to specify the following execution parameters when you add
this command to your script or process:
