BioStack 4 needs these dimensions to process microplates
with lids:
l Measure the height of the skirt on both long and short
sides of the plate. SLAS calls the skirt "flange."
l
Lid Grip Width: short side width measurement (see
image above).
l
Plate Grip Width: short side width measurement;
the plate is narrower at its top, where the gripper grabs
it, than its bottom, where the skirt widens.
l
Stacked Plate-with-Lid Height: the span from
the bottom of the plate to the bottom of the plate above
it when stacked with lids, excluding the protrusions on
top of the lid.
l
Plate-on-Lid Height: during processing the
BioStack moves an empty lid and the next plate to be
processed together. See below.
Measurements are recorded in
µm: microns or micrometers. Add
three decimal places to your mm
measurements.
Lid Dimensions
l Long side skirt height: Height of the plate skirt (or flange) on the long side of the plate
(from plate base to top of skirt) at its highest point.
l Short side skirt height: Same as above, on the short side.
l Lid grip width: The short-side width of the lid; tells the gripper how far to close when
gripping a lid.
l Plate on lid height: With a plate on top of a lid, the distance from the bottom of the lid
to the top of the plate. One step in the process moves the current plate's lid and the
next plate together to the carrier.
l Plate grip width: width (narrow side) of the plate, measured above the skirt (or
flange); tells the gripper how far to close when gripping a plate (as opposed to the
under plate grip) a plate.
l Stacked plate with lid height: Hold together a stack of plate/lid/plate. Measure base of
one plate to the base of the next plate.
Plate Lid Advanced Dimensions
Typically, the BioStack 4 will smoothly process plates with lids using the default
values for these parameters. However, if you experience processing problems, like
dropped lids, minor adjustments to these values may restore expected performance.
