PROBLEM TO BE SOLVED: To provide a storage device, storage rack, and storage shelf of sheet-like biological specimens, when storing/transporting frozen sheet-like biological specimens, suppressing degradation thereof due to an unintended thawing and easily storing and transporting the plurality of sheet-like biological specimens at a time.SOLUTION: A storage device 1 of sheet-like biological specimens according to the present invention, stores sheet-like biological specimens 50 for preservation and/or transportation. The storage device includes: a box body 3 having an opening at a peripheral wall a liquid-nitrogen absorber 5 disposed in the box body 3 for absorbing the liquid nitrogen and a storage part 7 for storing the sheet-like biological specimens 50 so as to be kept cold by the liquid nitrogen absorber 5 in which the liquid nitrogen is absorbed.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】凍結したシート状生体試料を保存/輸送するにあたり、意図しない解凍による品質低下を抑制し、一度に複数のシート状生体試料を保存・輸送することが容易なシート状生体試料の収納具、収納ラック及び収納棚を提供する。【解決手段】本発明に係るシート状生体試料の収納具1は、シート状生体試料50を収納して保存及び/又は輸送するものであって、周壁に開口を有する箱体3と、箱体3内に配設されて液体窒素を吸収する液体窒素吸収材5と、液体窒素が吸収された液体窒素吸収材5によってシート状生体試料50を保冷可能に収納する収納部7とを備えたものである。【選択図】 図1
