Abstract: A method for processing demineralized bone fibers, comprising a centrifuging step, and following the centrifuging step hydrated in sterile water to create a slurry; providing a tray to receive said fiber slurry; freezing the tray and fiber slurry; and lyophilizing the fiber slurry to create dried fibers.

Abstract: A cryogenic cooling manifold and methods incorporating a cryogenic cooling manifold for managing the gas layer(s) above a liquid cryogen to control cooling temperature-time profiles and ice formation for microliter and smaller samples that are plunged through the gas and into the liquid cryogen.

Abstract: A method and a cryogenic sample positioning system are provided which include: a sample holder cassette that is vertically coupled to a carousel gear through a first shaft. Each sample holder cassette has a first degree of rotation about the first shaft. A first planet drive gear underlies and is vertically coupled to the carousel gear through a second shaft that extends from the carousel gear through the first planet drive gear. The carousel gear has a second degree of rotation about the second shaft that is different from the first degree of rotation. A planet gear that is laterally connected to a second planet drive gear is interposed between each of the carousel gear and the first planet drive gear. Each of the planet gear and the second planet drive gear selectively define the first degree of rotation, without affecting the second degree of rotation of the carousel gear.
