Editing Microplate (section)

====Corner notch====
Although a corner notch (aka chamfer) is shown at the A1 (top-left) corner in the ANSI SLAS drawings, and many microplates do implement this A1 corner notch, in actuality the "quantity and location of chamfers(s) is optional",<ref name="ANSI SLAS 3-2004 link highlight" /><ref name="ANSI SLAS 3-2004 direct" /> so in practice the presence or absence of corner notches at additional corners (i.e. the bottom-left) is a proprietary implementation which causes difficulties with accessory cross-compatibility such as with [[microplate lids]] that may also implement the matching corner notch.
