Plate De-Lidding: How It Works
BioStack 4 Only.
Here is an overview of how the BioStack 4 handles plates with lids. Like all
BioStack processing, plates are pulled from the bottom of the input stack, i.e., the
bottom plate is the first one transferred, and returned to the bottom of the output
stack.
Important: Beware of condensation forming on lids. Do not process plates with lids when
the application causes condensation on the lids: the condensate may drip and contaminate
the plate, which could lead to false results. Review these guidelines: Prevent
Condensation on Plate Lids on the facing page.
n 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.
