What Opentrons tip racks look like

Here's what a standard tip rack supplied by Opentrons looks like:

Opentrons tip racks might also come with a sticker that looks like this (the product number and listed volume may differ):

GEB manufactures the tips used in Opentrons tip racks. Though the sticker says "GEB", Opentrons tip racks should not be confused with GEB tip racks:

GEB 1000uL

GEB 10uL


Opentrons tip racks labware definitions

Opentrons Python API

When loading labware definitions with the Opentrons Python API, Opentrons tip rack definitions will start with "opentrons".

For example, here are some Opentrons tip rack definitions:

opentrons_96_tiprack_10ul
opentrons_96_tiprack_20ul
opentrons_96_tiprack_300ul
opentrons_96_tiprack_1000ul

Opentrons tip racks have different labware definitions than GEB tip racks and can't be used interchangeably.

GEB tip rack definitions will start with "geb":

geb_96_tiprack_10ul
geb_96_tiprack_1000ul

Protocol Designer

As with the Opentrons Python API, Opentrons tip racks and GEB tip racks can't be used interchangeably when using the Protocol Designer.

GEB tip racks are no longer sold by Opentrons. This is why the GEB labware definitions are listed as "Retired" in the Protocol Designer:

Even though GEB tip racks are no longer sold by Opentrons, the labware definition for these tip racks are still available (both in the Opentrons Python API and the Protocol Designer) for users who still have GEB tip racks.

Note: GEB tip rack definitions may be removed from both the Opentrons Python API and the Protocol Designer in the future
