Freezing storage device

Abstract

A freezing storage device has a container body for storing a low-temperature liquefied gas, a cap for closing a mouth section of the container body and having insertion holes vertically penetrating through the cap, and ampoule receiving devices movably received in the insertion holes in the cap. The ampoule receiving devices each have a support pillar and ampoule receiving sections mounted vertically next to each other on the support pillar.

Description

technical field [0001] The present invention relates to a glove box (that is, a cryopreservation device) for accommodating cryopreservation containers, which can prevent frosting of ampoules when taking out ampoules stored in cryopreservation containers. [0002] This application claims priority based on Patent Application No. 2008-009393 filed in Japan on January 18, 2008 and Patent Application No. 2008-268768 filed in Japan on October 17, 2008, the contents of which are incorporated herein. Background technique [0003] Cryopreservation is generally used as a method for conveniently preserving biological samples such as sperm, fertilized eggs, and cells of experimental animals used in new drug development or basic medical research. In particular, the cryopreservation method using liquefied nitrogen is widely used because it enables stable storage for the longest period of time. [0004] In this cryopreservation method, the biological sample is stored in an ampule, and the...

Problems solved by technology

When frost adheres to the ampoule, the management code recorded on the surface of the ampoule becomes difficult to read, which becomes a cause of misoperation of the reading sensor

[0006] Moreover, when the frost adheres to the ampoule, the dust in the atmosphere also adheres at the same time, causing the ampoule to be contaminated
