Plates#

Microplates are modelled by the Plate class consisting of equally spaced wells. Wells are children of the Plate and are modelled by the Well class. The relative positioning of a Well is what determines its location. Plate is a subclass of ItemizedResource, allowing convenient integer and string indexing.

There is some standardization on plate dimensions by SLAS, which you can read more about in the ANSI SLAS 1-2004 (R2012): Footprint Dimensions doc. Note that PLR fully supports all plate dimensions, sizes, relative well spacings, etc.

Special Plate Tutorials#

Plate#

PLR is not actively enforcing a specific plate naming standard but recommends the following:

PLR plate naming standards

This standard is similar to the Opentrons API labware naming standard but:

  1. Further sub-categorizes “wellplates” to facilitate communication with day-to-day users, and

  2. Adds information about the well-bottom geometry.

(WIP)

Lids#

Plates can optionally have a lid, which will also be a child of the Plate class. The lid is modelled by the Lid class.

Measuring nesting_z_height#

The nesting_z_height is the overlap between the lid and the plate when the lid is placed on the plate. This property can be measured using a caliper.
