Abstract
A plate stacker is described for use in the field of sample analysis. The plate stacker increases the rate and ease with which sample carriers such as microwell plates may be interfaced with an automated system and includes a removable rack attached to a base to allow plates to be transported to and from an automated system. The stacker rack includes a door which allows for a compact stacker thus allowing manipulation of the microwell plates in a compact area. Generally, the plate stacker provides a means to allow a user to interface with an automated system. The rack portion of the stacker allows the user to load and unload microwell plates into the system in batches by loading or unloading multiple individual plates into or out of the rack. The base portion allows the automated system to load and unload individual microwell plates from the stacker.
