Pipette tip handling devices and methods

摘要

Discussed herein are methods and devices for storing, handling, loading or dispensing of pipette tips. Some embodiments allow repetitive loading of an array of multiple pipette tips that are stored in a nested configuration.

主权项

1. A plate through which pipette tips are ejected in a pipette tip dispensing device, comprising:
a substantially flat top surface, a substantially flat bottom surface and channels; which channels comprise a first subset of channels and a second subset of channels for retaining an array of the pipette tips; which channels comprise one or more channel features in or around each of the channels in the first subset of channels and one or more channel features in or around each of the channels in the second subset of channels, the one or more channel features confer a first frictional force to the pipette tips in the array ejected through the first subset of channels and a second frictional force to the pipette tips in the array ejected through the second subset of channels, and the second frictional force is different than the first frictional force.
