Introducing the BioStack | 5
and lid type and manufacturer. Another limiting factor is the total weight of the filled
plates in the stack cannot exceed 7.0 lbs (3.2 kg).
l When processing plates with lids the BioStack 4 performs several extra error-checking
movements, using its fingers to determine if the expected labware, i.e., a plate, lid, or
combination, is present. You'll observe several extra finger movements during
processing.
l
Except in Stay-On Lid Mode, lids are always
removed from the plates during processing even when the option to "Keep lids on
during read" is selected. In this case, the lid is removed briefly and replaced almost
immediately. Lid integrity is maintained: the lid removed from a plate is always the
same lid restored to the plate.
l A Plate Lid Definition file is required to process plates with lids.
n Gen5: Lid dimensions are stored in the Plate Type Database record. BioTek
updated the most commonly used plate type records with lid dimensions and
users can add more, as needed.
n LHC and touch screen liquid handlers: Several plate lid definition files are
provided to support the most common types of plates and new files can be
created. Important: A copy of the Plate Lid Definition file is attached to the
protocol for processing. The protocol no longer references the original lid
definition file, only its copy. If the original plate-lid definition file is modified,
those changes are not applied to the copies of the file attached to protocols.
n Keypad Liquid Handlers: Must use LHC to process plates with lids. Keypad
instruments can control the BioStack 4 when not processing plates with lids,
identical to BioStack 3 behavior.
l Certain plate types are not compatible with the de-lidding operation. Measure your
plate and lid type before use to verify they meet the minimum requirements:

plate type.
