Disclosed is a method for enabling the contents of a first chamber to be moved into a second chamber without exposing either chamber to elements making particulate-producing sliding contact. In one aspect of the invention, the method includes providing a carrier for a vertically spaced array of articles such as semiconductor wafers and having a clamping device for clampingly holding each of the articles; locating the carrier within the second chamber; opening the carrier by moving a first portion of the carrier upwardly from a second portion or,he carrier without producing sliding contact within the second chamber; and releasing the a clamping device without producing sliding contact within the second chamber, whereby the articles are accessible within the second chamber.
